  English, This research aims to develop a disaster medical tele-support system that can rapidly provide a telemedicine team with a digital twin reflecting the situation of a victim buried under rubble at a disaster site, such as an earthquake. For this purpose, we are developing a method to fit the size, pose, and joint positions of a standard 3D human mesh model to images of victims in the rubble taken by smartphones and 3D measurement point clouds and to transmit this information to a telemedicine team. In this report, as the first step, we experimentally evaluate the method's effectiveness by extending the training dataset so that the conventional 3D human body pose estimation and mesh restoration method based on deep learning can work stably even under high occlusion conditions such as debris.

  Japanese, A nurseʼs accurate, prompt physical assessment ability is connected directly with “quality of care”, such as an appropriate provision of the care method and the patient satisfaction. Lectures, audiovisual materials, simulated patients, and clinical practicum were mainstream skill acquisition methods for nursing students; the conventional devel opment of information science diversified it. Particularly, the development of the AR simulator expecting a high learn ing effect is aimed anatomical and clinical fidelity, and “Authenticity of the simulation education” before clinical prac tice is reobtained consensus. We have been developing a nursing AR simulator called Endotracheal Suctioning Training Environment Simulator (ESTE-SIM). We report our multi-disciplinary research progress, focusing on “devel opment of the respiratory tract model with the sensor”, “feedback mechanism of measurement data”, and “development of the facial expression and cyanosis model”.

  English, Scientific journal, Adolescent idiopathic scoliosis (AIS), the most common pediatric musculoskeletal disorder, causes a three-dimensional spine deformity. Lenke type 5 AIS is defined as a structural thoracolumbar/lumbar curve with nonstructural thoracic curves. Although a rod curvature will affect clinical outcomes, intraoperative contouring of the straight rod depends on the surgeon's knowledge and experience. This study aimed to determine the optimum rod geometries to provide a pre-bent rod system for posterior spinal surgery in patients with Lenke type 5 AIS. These pre-bent rods will be beneficial for achieving proper postoperative outcomes without rod contouring based on surgeon experience. We investigated 20 rod geometries traced in posterior spinal reconstruction in patients with Lenke type 5 AIS. The differences between the center point clouds in each cluster were evaluated using the iterative closest point (ICP) method with modification. Before the evaluation using the ICP method, the point clouds were divided into four clusters based on the rod length using a hierarchical cluster analysis. Because the differences in the values derived from the ICP method were <5 mm for each length-based cluster, four representative rod shapes were generated from the length-based clusters. We identified four optimized rod shapes that will reduce operation time, leading to a decreased patient and surgeon burden.

  English, International conference proceedings, Abstract. 3D point clouds from terrestrial laser scanners (TLS) are used in a variety of fields and applications. To acquire high-quality point clouds that have enough point density, small scanning errors, and no lack of points in important regions, appropriate scan planning, including determination of scanner positions and scan conditions, is required. Currently, planning is supported by knowledge and experience of skilled workers, and it is difficult to ensure the quality of acquired point clouds. In this study, we propose a system for visualization of point clouds to support the acquisition of high-quality point clouds using TLS. The system allows the user to see and check the quality of scanned TLS point clouds and unscanned regions intuitively by superimposing the point clouds onto the real world using a mixed reality (MR) device. In addition, the system supports finding the next best scanner position for additional laser scans based on predicted scan quality visualization to acquire higher-quality points or fill the unscanned regions.

  English, Scientific journal, OBJECTIVE: Accurate analysis to quantify cartilage morphology is critical for evaluating degenerative conditions in osteoarthritis (OA). Three-dimensional (3D) optical scanning provides 3D data for the entire cartilage surface; however, there is no consensus on how to quantify it. Our purpose was to validate a 3D method for evaluating spatiotemporal alterations in degenerative cartilages in a rabbit OA model by analyzing their curvatures at various stages of progression. DESIGN: Twelve rabbits underwent anterior cruciate ligament transection (ACLT) unilaterally and were divided into 4 groups: 4 weeks control, 4 weeks OA, 8 weeks control, and 8 weeks OA. 3D scanning, India ink staining, and histological assessments were performed in all groups. In 3D curvature visualization, the surfaces of the condyles were divided into 8 areas. The standard deviations (SD) of mean curvatures from all vertices of condylar surfaces and subareas were calculated. RESULTS: Regarding the site of OA change, curvature analysis was consistent with India ink scoring. The SD of mean curvature correlated strongly with the India ink Osteoarthritis Research Society International (OARSI) score. In curvature histograms, the curvature distribution in OA was more scattered than in control. Of the 8 areas, significant OA progression in the posterolateral part of the lateral condyle (L-PL) was observed at 4 weeks. The histology result was consistent with the 3D evaluation in terms of representative section. CONCLUSIONS: This study demonstrated that 3D scanning with curvature analysis can quantify the severity of cartilage degeneration objectively. Furthermore, the L-PL was found to be the initial area where OA degeneration occurred in the rabbit ACLT model.

  English, Scientific journal, BACKGROUND CONTEXT: Timely intervention in growing individuals, such as brace treatment, relies on early detection of adolescent idiopathic scoliosis (AIS). To this end, several screening methods have been implemented. However, these methods have limitations in predicting the Cobb angle. PURPOSE: This study aimed to evaluate the performance of a three-dimensional depth sensor imaging system with a deep learning algorithm, in predicting the Cobb angle in AIS. STUDY DESIGN: Retrospective analysis of prospectively collected, consecutive, nonrandomized series of patients at five scoliosis centers in Japan. PATIENT SAMPLE: One hundred and-sixty human subjects suspected to have AIS were included. OUTCOME MEASURES: Patient demographics, radiographic measurements, and predicted Cobb angle derived from the deep learning algorithm were the outcome measures for this study. METHODS: One hundred and sixty data files were shuffled into five datasets with 32 data files at random (dataset 1, 2, 3, 4, and 5) and five-fold cross validation was performed. The relationships between the actual and predicted Cobb angles were calculated using Pearson's correlation coefficient analyses. The prediction performances of the network models were evaluated using mean absolute error and root mean square error between the actual and predicted Cobb angles. The shuffling into five datasets and five-fold cross validation was conducted ten times. There were no study-specific biases related to conflicts of interest. RESULTS: The correlation between the actual and the mean predicted Cobb angles was 0.91. The mean absolute error and root mean square error were 4.0° and 5.4°, respectively. The accuracy of the mean predicted Cobb angle was 94% for identifying a Cobb angle of ≥10° and 89% for that of ≥20°. CONCLUSIONS: The three-dimensional depth sensor imaging system with its newly innovated convolutional neural network for regression is objective and has significant ability to predict the Cobb angle in children and adolescents. This system is expected to be used for screening scoliosis in clinics or physical examination at schools.

• EXTRACTION OF ROAD EDGES FROM MLS POINT CLOUDS USING BEND ANGLE OF SCANLINES

  ISPRS - International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, XLIII-B2-2020, 1091, 1097, Copernicus GmbH, 14 Aug. 2020, [Peer-reviewed]
  English, Scientific journal, Abstract. Efficient road edge extraction from point clouds acquired by Mobile Laser Scanning (MLS) is an important task because the road edge is one of the main elements of high definition maps. In this paper, we present a scanline-based road edge extraction method using a bend angle of scanlines from MLS point clouds. Scanline-based methods have advantages in that computational cost is low, it is easy to extract accurate road edges, and they are independent of driving speed of MLS compared to methods using unorganized points. In contrast, there are some problems with these methods where the extraction accuracy becomes low at curb cuts and intersections. The extraction accuracy becomes low caused by the scanning noise and small occlusion from weeds and fallen leaves. In addition, some parameters should be adjusted according to the mounting angle of the laser scanner on the vehicle. Therefore, we present a scanline-based road edge extraction method which can solve these problems. First, the points of the scanline are projected to a plane in order to reduce the influence of the mounting angle of the laser scanner on the vehicle. Next, the bend angle of each point is calculated by using filtered point clouds which are not vulnerable to small occlusions around the curb such as weeds. Then, points with a local maximum of bend angle and close to trajectories are extracted as seed points. Finally, road edges are generated by tracking based on bend angle of scanlines and smoothness of road edges from the seed points. In the experiments, our proposed methods achieved a completeness of over 95.3%, a correctness of over 95.0%, a quality of over 90.7%, and RMS difference less than 18.7 mm in total.

  English, Scientific journal, Abstract. Structure-from-Motion (SfM) and Multi-View Stereo (MVS) are widely used methods in three dimensional (3D) model reconstruction for an infrastructure maintenance purpose. However, if a set of images is not captured from well-placed positions, the final dense model can contain low-quality regions. Since MVS requires a much longer processing time than SfM as larger amounts of images are provided, it is impossible for surveyors to wait for the SfM–MVS process to complete and evaluate the geometric quality of a final dense model on-site. This challenge results in response inefficiency and the deterioration of dense models in 3D model reconstruction. If the quality of the final dense model can be predicted immediately after SfM, it will be possible to revalidate the images much earlier and to obtain the dense model with better quality than the existing SfM–MVS process. Therefore, we propose a method for reconstructing a more plausible 3D mesh model that accurately approximates the geometry of the final dense model only from sparse point clouds generated from SfM. This approximated mesh model can be generated using Delaunay triangulation for the sparse point clouds and triangle as well as tetrahedron filtering. The approximated model can be used to predict the geometric quality of the final dense model and for an optimization-based view planning. Some experimental results showed that our method is effective in predicting the quality of the final dense model and finding the potentially degraded regions. Moreover, it was confirmed that the average reconstruction errors of the dense model generated by the optimization-based view planning went below tens of millimeters and falls within an acceptable range for an infrastructure maintenance purpose.

  English, Scientific journal, Abstract. Laser scanning technology is useful to create accurate three-dimensional models of indoor environments for applications such as maintenance, inspection, renovation, and simulations. In this paper, a detection method of indoor attached equipment such as windows, lightings, and fire alarms, from TLS point clouds, is proposed. In order to make the method robust against to the lack of points of equipment surface, a footprint of the equipment is used for detection, because the entire or a part of the footprint boundary shapes explicitly appear as the boundary of base surfaces, i.e. walls for windows, and ceilings for lightings and fire alarms. In the method, first, base surface regions are extracted from given TLS point clouds of indoor environments. Then, footprint boundary points are detected from the region boundary points. Finally, target equipment is detected by fitting or voting using given target footprint shapes. The features of our method are footprint boundary point extraction considering occlusions, shape fitting with adaptive parameters based on point intervals, and robust shape detection by voting from multiple footprint boundary candidates. The effectiveness of the proposed method is evaluated using TLS point clouds.

• Generating facial expressions of pain with projection mapping for the nurse training simulator (1st report): Effect on the tracheal aspiration time for a patient with cerebral palsy

  Proceedings of JSPE Semestrial Meeting, 2019S, 860, 861, The Japan Society for Precision Engineering, 01 Mar. 2019
  English, Patients with cerebral palsy suffer from permanent movement disorder, and a nurse usually performs their tracheal aspiration where a tube must be inserted into the patient’s trachea. The tube insertion procedure must be performed quickly and carefully in order for the patient not to experience significant pain, anxiety, and even tracheal bleeding that would cause fear for the patient. To master such skill, many training opportunities should be provided for the novice nurses. Therefore, a training simulator is needed that could mimic the real situation of the procedure to provide an accurate and realistic feedback to the novice nurses. To realize that goal, we have developed a simulator that provides a head mannequin with the pain sensor attached and can project computer-generated patient’s facial expressions onto the mannequin face using projection mapping. The expression can change in conjunction with pain intensity the patient would receive due to the sputum blockage in the trachea and due to the hard contact of the tube tip with the trachea. The effectiveness of the projection mapping in the simulator is evaluated by comparing how fast trained and novice nurses finish the procedure when the facial expression of the pain is simulated or not.

  Japanese, Scientific journal, 3D laser scanners have recently been introduced for efficient as-built modeling in the heating, ventilating and air conditioning (HVAC) industry. Given their highly complex installation, when scanning the piping objects in HVAC systems using a terrestrial laser scanner (TLS), it is difficult to manually determine feasible scanner placement to capture the object areas required for renovation work at high accuracy and quality without occlusion. We propose an algorithm for a model-based optimum scan planning method for a TLS. This method uses a coarse 3D model generated by structure-from-motion, and finds optimal scanner placement that satisfies visibility, scan range, incident angle, and scan quality constraints. In this study, the optimal scanner placement problem is formulated as a 0-1 integer programming problem that is solved using the branch and bound method. In addition, a GPU significantly increases the speed of the precomputation of visibility constraints. In an evaluation, the proposed algorithm outperformed our previously proposed greedy method in terms of the number of scans and scan coverage ratio, and it shows performance equal to the greedy method in terms of modeling quality.</p>

  Introduction: Due to the advancement of the home-based healthcare, increasing the number of professionals who are able to administer homebased treatments, such as endotracheal suctioning, is an urgent issue.Methods: By measuring the ocular movement of nurses, nursing students and previous researches, an endotracheal suctioning ontology was visualized. It included a multiplex task structure, recognition, and judgment, as well as identifying procedures used during endotracheal suctioning that could contribute to a discussion on educational feasibility.Results: From the hierarchical structure of the constructed endotracheal suctioning ontology, not only the procedural knowledge but also knowledge about medical devices, knowing what options exist when endotracheal suctioning is ineffective, and a wide range of other expertise is needed to perform endotracheal suctioning safely.Discussion: An endotracheal suctioning ontology was created from the ocular movement of nurses. Ontologies are a potential tool for defining minimum requirements and the scope of ability that must be evaluated before clinical practicum.

• Variational digital hand modeling using image-based 3D model reconstruction
  Xie Yulai; Kanai Satoshi; Date Hiroaki
  Proceedings of JSPE Semestrial Meeting, 2013, 827, 828, The Japan Society for Precision Engineering, 2013
  English, A method for variational modeling of individual hands from a template hand model is described. The marked individual hand is reconstructed based on image-based multi-view 3D model reconstruction technique. According to hand joint anatomical knowledge, a single axis rotation assumption is proposed for estimating the joint axes and joint centers by the positions of dot markers at the backside of the hand skin in different hand postures. On the other hand, the skin surface of the template hand model is hierarchically partitioned into segments according to the hand surface anatomy by main creases on palmar side. The segments of the template hand model are scaled according to the feature dimensions of the reconstructed individual hand model. Finally, the template hand model scaled in segment-wise way is registered to the reconstructed hand model by a rough alignment process where the gravity center of the point sets on the creases of both models are matched and a fine alignment process where the segments of both models are matched based on ICP algorithm. Compared with previous works, the method is more subject-friendly, inexpensive, and efficient.

  Japanese, Scientific journal, Recently, changes of plant equipments become more frequent, and the construction of as-built models of the existing plant from laser scan data is expected to make the reconstruction processes more efficient. The purpose of this research is to propose an algorithm which can recognize a piping system from terrestrial laser scan data of plant equipments. The straight portion of pipes, connecting relationship of the piping system can be recognized in this algorithm. Eigenvalue analyses of the point clouds and of the normal vectors enable the recognition. Using only point clouds, the recognition algorithm can be applied to registered point clouds and can be performed in a fully automatic way. The recognition results of real plants have shown the effectiveness of the algorithm.

  Xie Yulai; Kanai Satoshi; Date Hiroaki
  Proceedings of JSPE Semestrial Meeting, 2012, 271, 272, The Japan Society for Precision Engineering, 2012
  English, Hand skin deformation is a significant role in the virtual ergonomic assessment of handheld products. In this paper, a nonlinear elasticity model is used to simulate the skin contact deformation, and quasi volume preserving property of skin is considered for more realistic simulation. An efficient contact solving method is developed for simulating the physical contact with product surfaces. The hand surface skin is partitioned anatomically into different regions for being able to specify different physical properties in them and for efficient simulation for the ergonomic assessment of grasp ability. The realistic contact deformation effect was efficiently realized, and was experimentally verified. The verification results show that the proposed skin deformable model is effective, in the acceptable range for virtual ergonomic assessment.

• Implementing Deformable Property of Skin in Contact of Digital Hand
  Xie Yulai; Kanai Satoshi; Date Hiroaki
  Proceedings of JSPE Semestrial Meeting, 2011, 273, 274, The Japan Society for Precision Engineering, 2011
  English, The virtual ergonomic assessment based on Digital Hand which estimates grasp posture and evaluates the quality of grasp is valuable for hand-held product design, because it can save the cost of test subjects, time, fabricating physical mockups, and it also enables objective evaluation. In this paper, we propose the method to implement deformable property caused by a contact between Digital Hand and the product surface by modeling the fingers as ″quasi-rigid″ objects, by constructing a physical model based on Boussinesq formula which approximates skin contact deformation mechanism, by detecting collision between Digital Hand and a product surface and enlarging the collision area, and then by finally solving Linear Complementarity Problem to resolve the contact and to produce the visible skin surface deformation. The plausible skin deformation could be obtained, because the method preserved the volume of Digital Hand before and after the skin deformation. In addition, utilizing the locality property of the deformation, the method can be easily used by the existing Digital Hand model and do not affect its original scheme of skin deformation caused by bending the finger.

• Approximative generation of springback compensation surface in stamping die design:generation of correspondence between reference geometry mesh and mesh the measured from real form product

  Proceedings of JSPE Semestrial Meeting, 2010, 95, 96, The Japan Society for Precision Engineering, 2010
  Recently, high strength steel sheets are rapidly introduced to automotive parts and amount of springback of these parts increases extremely. It is required to prevent the amount. However, mesh based on the measured from real formed sheets after springback does not have the same topology as the one of reference geometry mesh. However, different topology disables the user to use the proposed compensation estimation method. In this study, we propose a method where the correspondences can be found between the reference mesh and the measured mesh which has the different topology from the reference one, and which has the deformation relationship with it, under the preserving property.

• Euclidean Symmetry Detection from Scanned Meshes of Mechanical Objects based on a Combination of ICP and Region Growing Algorithms
  MIZOGUCHI Tomohiro; KANAI Satoshi
  Journal of the Japan Society for Precision Engineering, 75, 4, 554, 560, The Japan Society for Precision Engineering, Apr. 2009, [Peer-reviewed]
  Japanese, Scientific journal, Recently scanned meshes from mechanical objects can be easily acquired using high-energy industrial X-ray CT scanning technologies, and these meshes are widely used in various fields of product developments. Mechanical objects often exhibit symmetries for their functionality. They are originally defined by creating a copy of the solid and then by placing it with a certain transformation including an arbitrary set of translations, rotations, and reflections. Therefore it is desired to detect such symmetries from the scanned meshes for their effective use in mesh applications, such as reconstruction of CAD models with compact data representations or CAE mesh enhancement using the symmetries. In this paper, we propose a method that can detects multiple Euclidean symmetries from scanned meshes of mechanical objects based on a combination of ICP and region growing algorithms. We define Euclidean symmetries detection as to detect both pairs of regions that match under certain transformations and their transformations including arbitrary sets of translations, rotations, and reflections. We also propose a method that derives all possible sequences for reconstructing an entire model from the original mesh using planar-reflective symmetries among all the detected symmetries, and represents them in an AND/OR graph in order to compactly represent the mesh. Our proposed method contains several advantages. It can robustly detect symmetries from noisy scanned meshes that include many planar regions. Our method also can detect both global and local Euclidean symmetries from meshes. Moreover it can detect maximally large pairs of regions under user specified tolerances. We demonstrate the effectiveness of the proposed method from various experiments using X-ray CT scanned meshes of mechanical objects.

• Object-oriented Design Patterns for Parallel Discrete Event Simulation of Distributed Control Systems
  TOMURA Toyoaki; KANAI Satoshi
  Journal of the Japan Society for Precision Engineering, 74, 3, 306, 312, The Japan Society for Precision Engineering, 2008
  Japanese, Distributed control systems(DCS) consist of many sensors/actuators and a network interconnecting them, and are being introduced in various automation areas. For assuring the control performance of a DCS under heavy communication traffic, the precise simulation of the DCS is strongly needed. For this purpose, we propose a uniform, efficient and systematic method based on object-oriented design patterns for modeling and simulating DCSs. In this paper, two design patterns are newly proposed; Time-Warp pattern and Protocol pattern. Time-Warp pattern describes classes and interaction for executing the DCS simulation by communicating events having send/receive times, using Time Warp mechanism. Protocol pattern describes classes and interaction for uniformly structuring various communication protocol models used in DCSs, which are composed of the interactions among several layers and the state transition of each layer in a communication protocol. Finally, the effectiveness of the DCS simulator which is developed using these patterns was proved by comparing simulation results with the experiment results using the real DCS consisting of four CAN-based control nodes.

  MIZOGUCHI Tomohiro; DATE Hiroaki; KANAI Satoshi
  Journal of The Japan Society for Precision Engineering, 74, 7, 752, 759, The Japan Society for Precision Engineering, 2008
  Japanese, To effectively use scanned meshes obtained by 3D laser scanner or X-ray CT scanning systems in engineering applications, such as inspection and CAD model reconstruction, we need to segment meshes and extract desirable regions and their approximating surfaces. Surfaces of engineering objects are commonly represented by a set of analytic surfaces, such as planes, cylinders, spheres, cones. Therefore, the mesh surface of them needs to be approximated by a set of analytic surfaces. In this paper we propose an efficient mesh segmentation algorithm based on region growing and region merging. Our algorithm first robustly and accurately estimates mesh principal curvatures using the two-pass estimation method. Then it fast extracts regions and their approximating analytic surfaces based on region growing even if regions are smoothly blended. Finally it efficiently merges initial set of regions of large and complex scanned meshes under the user specified tolerances using region merging. We demonstrate the efficiency and accuracy of our algorithm with scanned meshes acquired from real engineering objects by X-ray CT scanning systems.

  Japanese, Scientific journal, In this paper, we present a parametric deformation method for mesh models based on barycentric coordinates for convex polytope. First, we propose a FFD (free-form deformation)based on barycentric coordinates. Arbitrary convex polytope can be used for the deformation handle of the FFD. Next, we propose an automatic handle construction method for the FFD based on definition and classification of deformation types. Deformation handles suitable for user intended deformation types can be automatically constructed by selecting the deformation type and model portions to be deformed. Finally, we propose a parametric handle deformation method driven by the affine transformation. In our method, user can deform the model by selecting deformation type, portions to be deformed, and by manipulating one or two deformation parameters. Moreover, we propose a method for preserving approximated geometric continuity at the boundary between deformed portions and non-deformed portions of the models. For this purpose, we impose geometric constrains derived from analysis of derivatives of barycentric coordinates on the deformation handle for each deformation type.

  Connecting some meshes is required for realizing mesh-based efficient CAE, for example, generating assembly models or setting analysis conditions. This paper proposes a new mesh combining method for triangular and tetrahedral meshes. First, the connectors which connect given two meshes are inserted, and then they are removed by the edge collapse simplification. As a result, a connected mesh that has coincident elements on the shared portions can be obtained. Our method is applicable to the meshes that have no-coincident elements and geometries on the portion to be connected, and it supports several types of mesh connections, i.e. curve-curve, curve-surface, and surface-surface connections.

  Japanese, Scientific journal, Recently, mesh models are easily obtained from several resources such as reverse engineering and searching 3D database. These mesh models are often used at the style design stage in product development. But at the detail design stage, solid models are necessary, therefore the technique which automatically generates solid models from mesh models is required for more efficient product development. In this paper, we propose a new method of feature edges extraction of triangular mesh models based on wide range normal evaluation and segmentation using modified Watershed method for generating solid models from mesh models automatically. We define feature edges as boundary edges of the region consisting of a set of triangles which should be recognized as a face. Our method is robust for scanning noise and differences of mesh connectivity, and it allows us to recognize the region bounded by extracted feature edges as a face. Our method also enables the extraction of boundary edges of fillet surface as feature edges, which was difficult by previous methods. Moreover we implemented the functions for selecting and collecting required feature edges which are extracted at different parameter settings for extractions by user interactions, and importing resulting feature edges into 3D CAD system.

  Japanese, Scientific journal, This paper proposes a new algorithm for fitting a Loop subdivision surface to dense sample points. Our fitting algorithm uses marching cubes and shrink-wrapping to fit the initial control mesh to the points measured from objects. It uses quasi-interpolation to quickly calculate the positions of initial control points from subdivision limit points and uses QEM- and curvature-based mesh simplification to preserve feature boundaries of the minute fillet regions so as to accurately fit to the feature edges. The effectiveness of our fitting algorithm was verified in reverse engineering of broad range of engineering mock-ups such as housings of a handheld wireless communicator, a cellphone, and a turbine blade. The resulting initial control mesh of the subdivision surface that was fit to over 10^6-point cloud had about several thousand of vertices with approximately 10^<-3> mean normalized fitting error.

  Japanese, Symposium, In this paper, we introduce a design system of textured shapes with small bumps using mesh-modeling techniques. Our system consists of three functions: 1) texture mesh data acquisition based on 3D scanning of sample texture material and texture extraction from existing textured models, 2) digital data processing of the texture mesh, and 3) textured shape modeling by combining meshes according to the user-specified region or direction of texture. These functions allow us to achieve effective textured shape design and prototyping.

  Japanese, Symposium, In this paper, we propose a mesh smoothing method with feature edge identification for mesh models including the measurement noise obtained from 3D scanner. First, by doing the eigen analysis of normal voting tensor, mesh edge groups that compose the feature edges can be extracted. Second, a bilateral filtering is applied to the extracted mesh edge groups in order to generate smooth edges along feature edge directions. Finally, by applying modified bilateral filtering to the overall mesh, the mesh model is obtained where the feature edges are smoothed along their directions and measurement noise included in faces surrounded by feature edges are removed.

For assuring the control performance of DCS under the heavy communication traffic, the simulation of DCS is strongly needed. For this purpose, we propose a uniform, efficient and systematic method based on object-oriented design patterns for modeling and simulating DCSs. In this paper, two design patterns are newly proposed. Statechart pattern describes classes and interaction for uniformly executing the state transitions in a finite state machine (FSM). Event-Chain pattern describes classes and interaction for uniformly dispatching the events among FSMs. The systematic procedures of implementation from the patterns to the Java code of the DCS model, are also discussed. Finally, effectiveness of proposed method was proved by developing a Java-based DCS simulator for distributed HVAC system.

  Japanese, Scientific journal, Low-quality triangular meshes with extremely distorted triangles are generated from several mesh generation approaches, including reverse engineering and solid model tessellations. However, such meshes have a negative effect on mesh applications such as digital geometry processing and finite element analysis. Therefore, a robust and fast algorithm for mesh quality improvement is strongly required. In this paper, we propose a new mesh quality improvement method based on mesh subdivision and simplification. In our method, we first subdivide the input mesh until the resulting mesh has a sufficient degree of freedom for topology modification. Then by simplifying the subdivided mesh based on the edge collapse according to the measure of mesh quality improvement, we are able to obtain the high-quality mesh. Our approach also generates the multiresolution hierarchy of a high-quality triangular mesh, which is also useful for several mesh applications. Finally, we show the effectiveness of our approach through applications with geometric models of industrial products and quantitative evaluations.

Our approach also generates the multiresolution hierarchy of a high-quality triangular mesh, which is also useful for several mesh applications. Finally, we show the effectiveness of our approach through applications with geometric models of industrial products and quantitative evaluations.

  Japanese, Distributed control systems (DCS) consist of many distributed sensors and actuators and a network interconnecting them, and are being introduced in various automation areas. For assuring the control performance of DCS under the heavy communication traffic, the simulation of DCS is strongly needed. For this purpose, we propose a uniform, efficient and systematic method based on object-oriented design patterns for modeling and simulating DCSs. In this paper, two design patterns are newly proposed. Statechart pattern describes classes and interaction for uniformly executing the state transitions in a finite state machine (FSM). Event-Chain pattern describes classes and interaction for uniformly dispatching the events among FSMs. The systematic procedures of implementation from the patterns to the Java code of the DCS model, are also discussed. Finally, effectiveness of proposed method was proved by developing a Java-based DCS simulator for distributed HVAC system.

  Japanese, Recently distributed control systems (DCS), which consist of many devices and a network interconnecting them, are introduced in various automation systems. For assuring the control performance under the heavy communication traffic, the simulation of DCS is strongly needed. For this purpose, we propose a uniform, efficient and systematic method based on object-oriented design patterns for modeling and simulating DCS. Two design patterns are newly proposed. Device-Constructor and Composite-Device-Constructor patterns describe classes and mechanisms for uniformly structuring device models composed of sensor and actuator models, and for uniformly structuring composite device models composed of device models. The systematic procedures of implementation from the patterns to Java code of the DCS model are also discussed. Finally, effectiveness of proposed method was proved in developing a Java-based DCS modeler and simulator for building automation area.

• Synthesizing Dynamic Facial Expressions of the Patient Model with Projection Mapping for the Nurse Training Simulator

  Tube insertion through trachea is a procedure performed by nurses to suck the sputum out of the patient's trachea. If the procedure is not performed carefully, it causes inconvenience and damages patient's trachea. To train novice nurses to practice the procedure in a safer environment, we developed a projection mapping-based nurse training simulator, and its effectiveness was evaluated. From the evaluations, it was found that more facial expressions, including choking, coughing, and patient's relaxed states, still must be integrated into the patient model so the nurse could be more immersed into the simulator. To achieve that, a Facial Action Coding System (FACS)-based video analysis tool is first used to identify the activated facial action units (AU) in those states and they are applied to the synthetic deformations on a 3D face of the patient model. The degree of naturalness, reality and effectiveness are evaluated.

  Introduction: Due to the advancement of the home-based healthcare, increasing the number of professionals who are able to administer homebased treatments, such as endotracheal suctioning, is an urgent issue.Methods: By measuring the ocular movement of nurses, nursing students and previous researches, an endotracheal suctioning ontology was visualized. It included a multiplex task structure, recognition, and judgment, as well as identifying procedures used during endotracheal suctioning that could contribute to a discussion on educational feasibility.Results: From the hierarchical structure of the constructed endotracheal suctioning ontology, not only the procedural knowledge but also knowledge about medical devices, knowing what options exist when endotracheal suctioning is ineffective, and a wide range of other expertise is needed to perform endotracheal suctioning safely.Discussion: An endotracheal suctioning ontology was created from the ocular movement of nurses. Ontologies are a potential tool for defining minimum requirements and the scope of ability that must be evaluated before clinical practicum.

• A Study on Rapid Reverse Engineering of Castings -A Separation of the Casting and Machining Surfaces from Scanned Triangular Meshes-
  浦田昇尚; 伊達宏昭; 金井理; 後藤孝行; 安田星季, 精密工学会誌(Web), 83, 5, 474‐480(J‐STAGE), 480, 2017
  Recently, it has become necessary to develop a more advanced reverse engineering (RE) technique that can generate CAD models of complex shapes from scanned mesh more efficiently. In this study, we propose a new efficient reverse engineering method of castings. In the method, machining and casting surfaces of the scanned mesh are separated, and precise surface fitting is applied only to the machining surfaces. The method can realizes an efficient RE process since different geometric processing and modeling techniques can be applicable to machining and casting surfaces individually. In addition, suitable geometric processes in the applications of the CAD models, such as machining margin addition and machining planning for machining surfaces in the duplication, can be automatically applied to each machining and casting surfaces, because they are recognized in our method. In this paper, we develop two methods. First, the surfaces are classified into the casting and machining surfaces based on triangle roughness. Second, boundaries of the casting surfaces are smoothed and modified so as to intersect machining surfaces for generation of the CAD models. We show some experimental results using some scanned meshes of castings., The Japan Society for Precision Engineering, Japanese
• 3D Monte Carlo localization using a depth camera and terrestrial laser scanner
  金井理; 畠山龍; 伊達宏昭, 写真測量とリモートセンシング, 55, 4, 235‐239,234, 239, 12 Sep. 2016
  

  The purpose of this study is to improve an accuracy and efficiency of 6DOF motion estimation in 3D MCL for indoor localization. Firstly, a terrestrial laser scanner is used for creating a precise 3D mesh model as an environment map, and a professional-level depth camera is installed as an outer sensor. GPU scene simulation is also introduced to upgrade the speed of prediction phase in MCL. Moreover, for further improvement, GPGPU programming is implemented to realize further speed up of the likelihood estimation phase, and anisotropic particle propagation is introduced into MCL based on the observations from an inertia sensor. Improvements in the localization accuracy and efficiency are verified by the comparison with a previous MCL method. The results showed that our proposed 3D MCL method outperforms the previous one in accuracy and efficiency.

  KITAHARA Tomonao; KANAI Satoshi, The Proceedings of Manufacturing Systems Division Conference, 2010, 0, 103, 104, 2010
  This paper proposes new 3D process planning system for MEMS device manufacturing. The process planning system can derive fabrication process from 3D MEMS device models based on the deposition precedence relationships between fabrication features. The basic of the method for the process planning was proposed by previous papers. The system can derive the fabrication process and the device model estimated to be fabricated by the fabrication process. And the shape of the device model which is difficult to fabricate is modified to fabricate shape, but it is likely to become the shape without satisfying the design specifications. To solve the problem, this paper proposes a redesign function which enables the designer to redesign the modified device model which has a manufacturable shape and satisfy the design specification based on the association of the device shape with the fabrication process., 一般社団法人 日本機械学会, Japanese

  We propose the method that detects Euclidean symmetries from scanned meshes of mechanical objects based on a combination of ICP and Region Growing algorithms. Our method can robustly detect Euclidean symmetries, including translation, rotation, and planar reflection, from noisy scanned meshes. Our method also can detect maximally large symmetries under the user specified tolerances from scanned meshes that contain many planar regions. The effectiveness of the method is verified by using various scanned meshes of mechanical objects., 一般社団法人 日本機械学会, Japanese

  A large amount of mechatoronic equipments for the material handling of vegetables and fruits have been introduced into the agriculture and the food manufactures in Hokkaido. However, the individual differences among the size, shape, and the mass of these products of are very large, and the verification of the mechanisms and the control systems is still verified in the try-and-error way using physical prototypes. This makes the development of the equipments time-consuming and expensive. In this research, a virtual prototyping tool was developed intended for the design of "automatic potato grader". First, 3D grader mechanism model with 3D "potato geometry model" was built, and the operation of the grader part was simulated in cooperation with the control program mounted on the real PLC., 一般社団法人 日本機械学会, Japanese

• 2305 Fast Calculation of the Yield Prediction for Semiconductor Manufacturing
  KANAI Satoshi; FUJIWARA Yoshitaka, The Proceedings of Manufacturing Systems Division Conference, 2008, 0, 75, 76, 2008
  With the higher density of semiconductor devices, the yield prediction simulations such as the CAA (Critical Area Analysis) generally have to take a few days. Therefore, faster calculation is needed to reduce the elapsed time of the prediction. This study aims to propose a management structure of the design layout data which enable the elapsed time of CAA simulation to be considerably faster than the current one while still keeping the simulation accuracy unchanged. A management structure of the layout data using the range tree and interval tree and a prediction method of the query range size were developed to make the 2-dimensional range query in the CAA faster. The CAA calculation which is 10 times to 500 times faster than the current one was achieved., 一般社団法人 日本機械学会, Japanese

In this paper, we introduce our multiresolution mesh modeling system that can satisfy above requirements. Our system includes the functions that allow us to use several kinds of meshes in the CAE ; mesh properties control, mesh density control, feature suppression, and mesh combining. The effective use of them in the CAE is also described., 一般社団法人 日本機械学会, Japanese

  Recently, concerns on CSR (Corporate Social Responsibility) have been raised and legal regulations for the environment have spread. Companies are required to disclose how the production activities give influences on the environment. Under this situation, information management systems that can manage chemical substances included not only in the final product, but also intermediate products, byproducts and consumed energy, are required. Such systems must be able to trace each lot from products up to composing materials and vice versa for risk management. The purposes of this research are to design a process and product model for batch production, and to develop a prototype of a batch production information management system that can accommodate environmental CSR. We first designed a model as a set of process elements that contain substance and energy information that is required for accommodating environmental CSR. Then, we developed a system on Object-Relational database management system, and verified traceability that specifies material lot number from product lot number., 一般社団法人 日本機械学会, Japanese

  ENDO Yui; DATE Hiroaki; Kanai Satoshi; Kishinami Takeshi, The proceedings of the JSME annual meeting, 2004, 0, 59, 60, 2004
  In terms of smooth surface generation over arbitrary topological mesh, simplicity of geometric calculation, and easiness of LOD, subdivision surface has the attractive features as a surface to be fit in reverse engineering (RE). Recently, several fitting algorithms have been proposed for RE using subdivision surfaces. However, these are not suitable for RE in the industrial design process where the physical mock-up models have very complex product geometries. To solve this problem, we propose a new method for fitting a Loop subdivision surface to a given high resolution point cloud by using a quasi-interpolation and a non-uniform subdivision algorithm. The resulting initial control mesh that was fit to about 1,000,000 points had 12,000 faces with 10^<-6>6 normalized fitting error., 一般社団法人 日本機械学会, Japanese
• Feature Edge Extraction on Triangular Mesh Models based on Wide Range Normal Evaluation and Segmentation
  Mizoguchi Tomohiro; Date Hiroaki; Kanai Satoshi; Kishinami Takeshi, The proceedings of the JSME annual meeting, 2004, 0, 61, 62, 2004
  Recently, triangular mesh models are widely used in product design and manufacturing. However, too many triangular patches are required for representing complex shapes accurately and it is also difficult to handle a meaningful set of triangular faces. To solve these problems, we propose a feature edge extraction method of triangular meshes based on segmentation using modified Watershed method and wide range normal evaluation. The proposed method robustly extracts feature edges from noisy mesh models, and enable to handle mesh models efficiently., 一般社団法人 日本機械学会, Japanese

  The coordination of exterior style design and interactive design of GUI (Graphical User Interface) greatly influences the market competitiveness of numerous IT products, such as cellular phones, PDAs and digital appliances, and therefore must be reviewed early in the design stage. For efficient design review, a unified 3D virtual prototyping tool is needed for designers where both the styling of a product's exterior and GUI's.dynamic behaviour can be evaluated simultaneously. We developed a geometry-behaviour collaborative prototyping tool based on STEP (ISO10303) standards. This tool can be associated with the STEP AP203file of a 3D geometric model from 3DCAD, then the behaviour of the GUI can be defined according to the 'STEP behaviour schema' using EXPRESS language. Finally, in our prototyping, the behaviour model can be mapped into the animation script of a particular Web3D format. The designers can fully examine the usability and functionality of the GUI using the working prototype on Web3D browser., 一般社団法人 日本機械学会, Japanese

  Date Hiroaki; Kanai Satoshi; Kishinami Takeshi; Iwakoshi Mutsuro; Kobayashi Masayoshi, The proceedings of the JSME annual meeting, 2004, 0, 249, 250, 2004
  The surface of many industrial products can be considered to have geometries consisting of a base shape and surface textures, such as detailed geometrical patterns, logotypes and symbols. In this paper, we propose a textured shape design method based on mesh-based texture integration, and introduce an efficient prototyping system of the textured shapes using proposed method and stereo lithography. In this system, we can simply generate the mesh model with texture, and the resulting mesh model can be directly applicable to stereo lithography. Therefore, prototypes of textured shapes can be produced efficiently., 一般社団法人 日本機械学会, Japanese

  DCSs (distributed control systems) consisting of many devices and an open network are used in factory automation and building automation areas. Before making the actual DCS, we must accurately estimate the control characteristics of network in the DCS. In this paper, we propose two object-oriented design patterns which specify the structure and behavior of the communication protocol of devices, and synchronize the clocks of components in the DCS model. Finally, we evaluate the correlation between the result of DCS simulation using the CAN protocol model and the network communication of the actual CAN-based DCS., 一般社団法人 日本機械学会, Japanese

  We have developed an appearance-design-CAD-coupled simulation framework that will enable engineers to perform analysis simulations during the appearance design process. This is not only a prototype process, but also the most innovative product design process to date. We applied multi-resolution representation technology to an automatic mesh generation system, in order to obtain low-resolution analysis meshes from high-resolution appearance design meshes. Because engineers are able to design appearance and function all at once, we can eliminate redesigns caused by design defects in the original function design process., 一般社団法人 日本機械学会, Japanese

• Triangular Mesh Modeling of Surface-detail-integrated Shape using Parameterization
  DATE Hiroaki; KANAI Satoshi; KISHITANI Takeshi, Journal of the Japan Society of Precision Engineering, 69, 4, 581, 585, 05 Apr. 2003
  The surface of many industrial products may have geometries composed both of base shape and surface detail. From the design point of view, it is efficient to design the base shape and surface detail independently, and then to integrate the surface detail with the base shape surface for obtaining the surface-detail-integrated shape. In this paper, to realize a flexible and efficient mesh modeling for the surface-detail-integrated shape, we propose a method that integrates the surface detail with the base shape using parameterization. In our method, the user can simply design the surface-detail-integrated shape by specifying the references of integration for the base shape and surface detail, which makc positional and directional correspondence between both shapes. Surface detail integration is automatically done so as to satisfy the geometric constraints of the surface detail on the integrated shape based on successive expansion and local modification of parameterization. Finally, we demonstrate our method with several examples and evaluate the accuracy of integration, and discuss the approach which can improve the precision of surface detail integration., The Japan Society for Precision Engineering, Japanese
• A Verification of Graphical Behavior of Distributed Control Systems Using Java 3D and Object-oriented Design Patterns
  TOMURA Toyoaki; KANAI Satoshi; KISHINAMI Takeshi, 旭川工業高等専門学校研究報文, 40, 40, 21, 30, Mar. 2003
  Distributed control systems (DCSs), which consist of a plant, a controller composed of many devices, and an open network interconnecting devices, are now used in many automation areas. For assuring the control performance under the heavy traffic on the network, the simulation of DCS is strongly needed. In the case of DCSs for controlling an mechanical plant, the graphical and cooperative simulation between the controller model and the plant model becomes important to verify the sequence of motions of the plant. For this purpose, we propose a systematic object-oriented-based DSC modeling procedure to efficiently and uniformly develop the DCS simulation model. From this procedure, we can describe the formal description of DCS simulation model based on five object-oriented design patterns which describe the structure and behavior of the DCS. We also propose an event chain mechanism between the statechart-based controller medel and the graphical plant model. Finally, a cooperative DCS simulation software is developed by using the Java 3D API., 旭川工業高等専門学校, Japanese

These behaviors can be expressed as Statecharts : a finite state machine with hierarchical states and with guards of transitions. In this research, Statechart-based automated testing method on software for FA is proposed. Generation of test sequence for testing on state-transitions and of test data for testing on guard conditions could be fully automated from Statecharts, and critical error in implementation could be tested systematically.

  In the operation planning of 3-D free-form machining for die and cavity shapes, a series of intermediate shape models must be designed as the references of NC programming. In this paper, we apply a new wavelet-based multi-resolution analysis to the representation of a series of intermediate shape models for free-form surface machining. The proposed wavelet-based approach enables very compact data representation for these models, and enables the geometric relations between each resolution model to be designed so as to avoid overcut and to level the cutting loads. The effectiveness of the approach was verified through the simulation for practical free-form shape models., The Japan Society of Mechanical Engineers, Japanese

  A multi-resolution representation and its LOD control become necessary for efficiently processing a texture-mapped polygonal model with huge faces and high-resolution texture images.For this purpose, first we propose a re-meshing algorithm where the texture-mapped polygonal model with arbitrary topology can be converted into the one with semi-regular topology suitable for wavelet transform.Then, we discuss how to compose the multi-resolution representation of the texture-mapped polygonal model where the resolutions of the polygon geometry and the texture image can be individually controlled by respectively applying the 3D and 2D wavelet transforms to the polygonal model and to the texture images of the re-meshed model., 一般社団法人情報処理学会, Japanese

• Deigital Watermarking for 3D Polygons Based on Wavelet Transform
  DATE Hiroaki; KANAI Satoshi; KISHINAMI Takeshi, Journal of the Japan Society of Precision Engineering, 65, 9, 1275, 1279, 05 Sep. 1999
  Recently, muchi, interest is being taken in method to protect the copyright of digital data and preventing illegal duplication of it. However, in the area of CAD/CAM and CG, there are no effective ways to protect the copyright of the 3D geometric models. As a first step to solve the problem, a new digital watermarking method for 3D polygonal models is introduced in this paper. Watermarking is one of the copyright protection methods where an invisible watermark is secretly embedded into the original data. The proposed watermarking method is based on the wavelet transform (WT) for the polygonal model. The watermark can be embedded in the large wavelet coefficient vectors at various resolution levels of the transformed model. The method makes the embedded watermark imperceptible and invariant to the affine transformation. And also makes the control of the geometric error caused by the watermarking reliable. Finally, the effectiveness of the proposed watermarking method is shown through several simulation results., 公益社団法人精密工学会, Japanese

• A Study on Virtual Reality of NC Programming for Free-Form Surfaces
  TAKAHASHI Hidetomo; KANAI Satoshi, Journal of the Japan Society of Precision Engineering, 62, 1, 70, 74, 05 Jan. 1996
  When we generate the cutter path for free-form surfaces by a CAM system, we have to minimize the aircut of it and to ensure the accuracy of the machined products. But it is very difficult for the conventional CAM system to set the adequate cutting condition and to generate the path only for the part to be cut. On the other hand, a profiling machine has been commonly used by die-manufacturers, because it enables the workers to directly generate the cutter path during monitoring the cutting situation. However a profiling machine needs the master-model of product and the accuracy of the cutter path is not high. Therefore we introduce the virtual reality into NC programming system for free-form surfaces. And an accurate virtual profiling system without master-models was realized. The worker can manually profile the model in the computer and can generate NC data for free-form surfaces by using the proposed system. In this paper, the construction of the virtual profiling system is described. The virtual profiling system consists of a bilateral master-slave system which has a 3DOF orthogonal direct drive manipulator, a profiling simulation software, and a cutting simulation software. The virtual profiling system can generate the cutter path for free-form surface models in real time with the accuracy of ±0.1μm., 公益社団法人精密工学会, Japanese

  This paper presents the system which enables a style designer to generate 3 dimensional free-form curve models in a computer easily as if he draws rough sketches on paper. The system consists of three modules; the user-interface module which enables a designer to draw rough sketches in the form of perspective projection directly on the display, the module to automatically recognize geometric and topological constraints on the rough sketches, and the module to calculate 3 dimensional points and free-form curves based on these constraints. The process of these modules can be quickly executed during the interaction of the designer with the computer. Finally some examples of the processing are shown, and efficiency of the system is evaluated., 公益社団法人精密工学会, Japanese

  This paper deals with an automatic marking system for large castings and forgings. The developed automatic marking system consists of three subsystems ; that is the 5-directional 3-D object (or form) measuring system to obtain the entire workpiece shape, the automatic matching software to determine the relative position of product model in the measured workpiece model space, and the automatic mark scribing system to scribe marks on the workpiece for indicating the determined position. Satisfactory results have been confirmed by some experimental tests., 公益社団法人精密工学会, Japanese

  This paper describes the software structure of the proposed automatic marking system to shorten the set-up time for large castings and forgings. The system mainly consists of two modules ; the first one is to determine the relative position of the required shape into the workpiece, and the second one is to calculate the NC data for the scribing lines. The proposed software system accepts both the workpiece shape data from the developed measuring system and the geometric model of the required shape from the CAD system. Also it adjusts the position and orientation of the geometric model in the workpiece space, makes the stock removal uniform around the workpiece, and generates NC data for the scriber based on these models. Satisfactory results have been confirmed by some tests., 公益社団法人精密工学会, Japanese

In order to realize a high level computer controlled machining system, it is necessary to develop the machining simulation technique which is able to forecast machining phenomena such as removal shape and cutting force, cutter collision and so on. Voxel representation is introduced into the machining simulator, which makes it easy to do a logical set operation between objects, and the conversion process from modeling space to voxel space is proposed. Some experimental results of the simulator are also demonstrated., 公益社団法人精密工学会, Japanese
• A Study on an Automatic Marking System for Large Castings and Forgings (1st Report) : Development of Non-contact Distance Measuring Sensor and 5-Directional Measuring System for Recognition of Workpiece Shape
  YOKOUCHI Hirotaka; HAYAKAWA Tamotsu; KIKUCHI Kazuyuki; KANAI Satoshi; KISHINAMI Takeshi, Journal of the Japan Society of Precision Engineering, 54, 12, 2353, 2358, 05 Dec. 1988
  The paper proposes a computer-aided 3-dimensional shape measuring system which consists of 5-directional measuring machine installed with a newly developed non-contact distance sensor, and processors provided to transform the measured distance data to coordinates then also to construct entire mesh point data of the object workpiece. The distance sensor is based on an astronomical telescope typed optical system, equipped with laser tube and one dimensional CCD set horizontally on the optical axis. The device has following features : (1) wide range of measuring distance, (2) high measuring rate, (3) linear measuring characteristics, (4) less hidden effect and (5) compact size. The system is one of the sub-systems in a more comprehensively computer-aided marking system which, also having been realized in the same period, executes automatically all processes concerning to marking operation for large sized workpiece produced by casting and/or forging. Some test results of the measurement are presented constructing mesh point data model of the entire surface for a few typical workpieces., 公益社団法人精密工学会, Japanese

• Cell-Constructed-geometric-Model (CCM) and Its Modelling System
  KANAI Satoshi; TANAKA Fumiki; KISHINAMI Takeshi; SAITO Katsumasa, Journal of the Japan Society of Precision Engineering, 52, 10, 1808, 1814, 05 Oct. 1986
  The Cell-Constructed-geometric-Model (CCM) is proposed as a new conception for the data representation of geometric model. The CCM consists of three-dimensional array of some finite Cells. The Cell means a unit volumetric solid bounded by six curved surfaces, and is regarded as an extended idea of bi-cubic parametric surface interpolation to a tri-cubic one. The interpolative method of the CCM is a rational cubic Bézier's. Therefore, with the CCM, it is possible to represent a closed volumetric solid bounded by some analytic surfaces and sculptured surfaces using the same data structure. This paper describes the mathematical formulation and the internal data structure of the CCM. Then the application of the CCM to the geometric model for CAM system, Finite-Element-Analysis, and calculation of weight and volume of a solid, are considered. Finally, developed geometric modelling system and methods of modelling to make the CCM interactively are described, and a modelling example of the CCM is shown., 公益社団法人精密工学会, Japanese

  研究者らは今まで、ダイナミックプロジェクションマッピング技術を用いた気管内吸引シミュレータ（ESTE-SIM）を共同開発し、吸引カテーテル操作の巧緻による表情や顔色の変化などの生体反応を呈示するシミュレータとして開発と評価を継続してきた。また、シミュレータを用いた教育における学習効果の客観的指標として、看護師群と学生群の視線と動作解析により学習効果を検証してきた。そこで本研究の目的は、①医療事故の体験も可能な在宅人工呼吸器の複合現実シミュレータを開発し、②機械学習を用いた特徴量抽出による学習評価アルゴリズムの構築の2つを目的としている。
  
  
  2023年度までに、①については、人工呼吸器測定値モニタの波形変化を体験可能なアプリ（Simmar：二宮研究室開発）をESTE-SIMを統合し、「人工呼吸器装着中の気管内吸引」がトレーニング可能なシミュレータ（Simmar+ESTE-SIM）を開発した。本シミュレータは、管見の限り「世界初」の人工呼吸器XRシミュレータであり、「手技に応じた生体反応を呈する看護シミュレータESTE-SIMと人工呼吸器シミュレータSimmarの統合」としてSI2023にて発表した（小水内ら，2023)。専門分野を問わず反響が大きく、日本ロボット学会誌、Precision Medicineより原稿執筆依頼があった。2023年12月には基幹技術の特許を取得しており、現在、論文を投稿中である。②に関しては、The 5th International Conference on Activity and Behavior Computing(ABC2023)，Best Paper Awardを獲得した。

  本研究では、①医療事故の体験も可能な人工呼吸器複合現実シミュレータの開発と、②機械学習を用いた特徴量抽出による学習評価アルゴリズムの構築を目的としている。
  
  
  ①に関しては、広島国際大学の二宮教授ラボにおいて人工呼吸器の操作パネルと測定値グラフの表示が可能な人工呼吸器トレーニングアプリSimmarを開発いただき、関東圏の2大学において大学院生約40名を対象としたユーザテストとアンケート調査を実施した。その結果、卒後1年目から人工呼吸器に携わったと回答した者が30名(71.4%)、学部レベルでSIMMAN-ALS5000を使用した経験のある12名のうち、8名が満足したと回答し、4名が不満と回答した。大学院レベルでSIMMAN-ALS5000を使用した17名のうち、12名が満足したと回答した。まともに習ったことがないという自由記載も認められた。同時に、特別支援学校における人工呼吸器装着児への看護師のかかわりについて360度動画教材を開発し、アンケートを実施したところ、教材の難易度について、学部3年次の学習内容として適切と回答した者が約8割、学部4年次として適切と回答した者が同じく約8割であった。2023年度はこれらの結果と学会発表後のディスカッションを踏まえ、教材の難易度を設定する。
  
  
  ②に関しては、九州工業大学の井上教授と共に機械学習において抽出すべきタスクについて検討し、先行研究に基づき、手袋着用から手袋廃棄までの気管内吸引の一連の流れを1回の気管内吸引とし、吸引前の判断指標となる「肺音聴診」、吸引後の看護介入である「体位ドレナージ」を含めた行動認識のためのアノテーションを進めている。翌年度は、習熟度を判定する分類器の開発を進める。

We developed methods for estimating the scan quality of 3D scan data (point clouds), methods for supporting 3D scan data acquisition to efficiently acquire high quality 3D scan data, and basic processing methods of 3D scan data based on the scan quality. The effectiveness of the methods were evaluated through experiments using real scan data of some environments and structures.

  To provide safe and effective tracheal suctioning, prompt and multiangle decision and delicate catheter operation must be acquired. We developed a Projection Mapping simulator which shows biological reactions of an adult patient by 3D Computer Graphics to train above mentioned skills. Several scenarios which frequently clinically occur, e.g. the drop of the arterial oxygen saturation by the prolonged suctioning time, was created. Using such scenario, experienced nurse's and nursing students' eye movement and motion was inspected to quantify the learning curve to obtain judgment skill and delicate suctioning catheter control. Particular results were shown about the difference of eye movement and motion between the nursing student group and the nurse group.

  This study aims at development of an evaluation method of road surface from the viewpoint of road users and the establishment of a high-level PMS.
  
  
  Firstly, we designed the traveling scenario of driving simulator (DS) collecting point cloud data at real roads acquired by Mobile Mapping System (MMS) device and meteorological data so as to show drivers sequence of images of road and its surroundings super-realistically. Then we carried out the experiment using the DS to evaluate road surface based on subjective rating and physiological response of the drivers. The result suggests that heart-rate variability correlates well with the subject rating. Furthermore, we conducted physiological response analysis by the DS in consideration of driving situations.The analysis result enables identification of Kansei expression corresponding to road surface characteristics and it represents a way of modeling road surface evaluation for the road maintenance and serviceability in terms of road users.

  In this research, some methods for combining several 3D scan data from various 3D scanning systems and optimized scanning in order to obtain high quality 3D scan data of large-scale environments and structures. For combining several 3D scan data, efficient automatic registration methods for 3D scan data acquired from terrestrial laser scanner, mobile laser scanner, handy scanner, and structure from motion are developed. For optimized scanning, methods to estimate best laser-scanner positions which allow us to acquire high quality point clouds with a smaller number of scanning, considering scanning importance of the objects and laser-scanning properties, are developed.

  The goal of this research is to realize the accessibility evaluation of "as-built" environments based on the detailed human behavior simulation. To this end, we propose a method where as-built 3D environment models can be constructed in a fully automatic way from laser-scanned 3D point clouds measured from as-built environments. Additionally, we propose an advanced walking simulation function of the digital human model (DHM) in the as-built environment models. The proposed simulation enabled a DHM to automatically walk utilizing the functions of the global path findings, the walking path location control, the local collision avoidance and the walking motion generation. Moreover, we applied our modeling and simulation algorithms to the complex as-built environments such as a two-storey indoor environment, and an outdoor environment which includes slopes. The efficiency and effectiveness of the modeling and simulation were confirmed.

  The purpose of this research is to develop software where legacy mesh models for analysis can be retrieved using a query of a hand written sketch or sampled point data from physical model, where a new mesh model for analysis for a new design idea can be obtained quickly by deforming the legacy models so as to fit to the sketch or sampled points.

• Research on Digital semantic product model for product life cycle support

  The manufacturing industry is increasingly dependent on digital tools, such as CAD, CAE, CAM, product data management (PDM) systems CNC machines to design and manufacture products. Moreover, the movement toward concurrent engineering drives the need for frequent transformation of the product data between different digital tools. In order to realize the articulate link between design and manufacturing and the traceable manufacturing system, it is necessary to realize interoperable digital tools which represent the semantics of information independently of any implementations. Interoperability characterizes the ability of product model data to accurately represent objects in all collaborative engineering environments. Today, all engineering data, such as geometry representation data, tolerance data, etc., are not used throughout product development processes. An interoperability error makes product model data unusable when applying digital tools. If an interoperability error arises in collaborative engineering applications, tracking the error back to its source is expensive (if not impossible) and requires a significant amount of time. Moreover, the quality of data that represent information should be ensured during the product life cycle. In this research, the Digital Semantic Model that fulfills the above requirements was proposed.
  The digital semantic product model consisted of the quality assurance of the product model data, the semantic modeling for humans (such as designer and worker), understandable and computer readable data, and the functional modeling for supporting the product life cycle. In order to ensure the product model data, the Product Data Quality Checking method for the ISO Standard product model was proposed. In order to support all of the product lifecycle activities, the functional model for each activity was developed based on the related ISO Standard. In order to represent the semantics of the data, the EXPRESS language for data modeling and XML for representing the data, was adopted.

  The purpose of this research is to develop a virtual functional evaluation system for designing automatic machinery where multi-disciplinary simulators for workpiece deformation, machine kinematics and control software can be coordinated and collaborated each other, and where the realistic behavior of the machine can be simulated.The results of the research were summarized as follows :(1)A methodology and a developing environment were proposed where commercial off-the-shelf kinematic simulator and control software simulator could be communicated real-time using RTI middleware compatible with the distributed simulation standard HLA. The environment was applied to verify the dynamic behavior of a CD drive mechanism under control, and it was confirmed that several kinds of hidden mechanical and control design mistakes could be easily found by using this environment.(2)To realize the efficient simulation time advancement in the collaborative simulation among different simulators, the Time Warp mechanism was developed where the time step could vary in each federate. This mechanism was implemented in federates of the collaborative simulation, and it was confirmed that the simulation efficiency of the automatic machinery controlled by the FieldBus was greatly improved.(3)To predict the workpiece deformation by FEA for verifying the automatic packaging machine, a multi-resolution FEA mesh generation method was developed where the number of elements and geometric qualities of the elements can be controlled flexibly. And a deformation simulation algorithm of thin packaging film based on discrete shell model was implemented, and the defects of the packaging process caused by the fine creases could be predicted to some extent.

  A significant amount of research for machining process planning and machining feature extraction has been carried out for realizing an integrated CAD/CAPP/CAM system. The Standard for the Exchange of Product model data (STEP) has also emerged as a viable method for product model data exchange among design activities. However, a consistent STEP/AP set for integrating design, process planning and machining for mechanical components has not completely been developed thus far, because process planning is very complicated for analyzing a process and making a support data model, and STEP is intended to concentrate data communication on the area of design and management process. To solve this problem in this project, we perform the following items:
  1. Establishing a information modeling technology that enable us to archiving and sharing the machining knowledge and information of machining resources in a manufacturing system
  2. Implementing the integrated manufacturing design system based on the proposed information modeling technology of the machining knowledge and machining resources.
  3. Making a process plan for a mechanical part using the proposed integrated manufacturing design system.

  The purpose of this research is to develop the new digital watermarking methods for 3D geometric models in the area of CAD, CAM, CAE and CG.Watermarking is one of the copyright protection methods where an invisible watermark is secretly embedded into the original data. The proposed watermarking method is based on wavelet transform and multi-resolution representation of the 3D geometric models.In this research, large-scale polygon, solid and surface models were firstly designed using commercial 3-D CAD systems. Then the series of operations consisting watermark embedding on these models, coordinate transformation and modification of models, and watermark extraction were executed in order to evaluate the performance of proposed watermarking method.The robustness of the watermark for external attacks, capacity of embeddable watermark and the geometric error caused by watermark embedding were evaluated quantitatively. The following results were obtained ;(1) The embedded watermarks were completely kept under the affine transformation.(2) The geometric error of the models caused by the embedding could be easily kept within the specified tolerances.(3) The embedded watermarks were robust to the several attacks such as noise superposition and vertex modification on the models.(4) The embedded watermarks were not robust to the cropping operation for the models.Furthermore, the developed watermarking method was improved so as to be applied to the watermarking for 2D vector data such as digital map. As a result of the experiment, it was verified that the visual quality of the data could be kept, the capacity of the watermark was large enough to store the copyright data, and the watermark was very robust to the noise superposition on the vertex coordinates.In the future, the modification of the algorithm will be necessary so that the embedded watermark becomes more robust to the cropping operation for the 2-D or 3-D geometric models.

  1998 - 1999
  KISHINAMI Takeshi; TANAKA Fumiki; KANAI Satoshi
  This research deals with feature models of a machining operation and machined shapes for single cutting edge machining, which correspond directly to the machining process model. The feature model of the machining operation is proposed from the viewpoint of the dimension of a macro cutting tool, the dimension of feed motion, and the number of enveloping constraints. The feature model of the machined shape is also proposed from the viewpoint of the removal volume, the machined surface, and the surface texture. The linkage between both feature models is accomplished by the concept of a working tool. The working tool consists of the swept macro tool, the envelope of the swept macro tool, and the working edge. We proposed the abstract model of the machining process and the abstract model of operation planning which may represent the linear equations. We also pointed out that there are only 15 types of machining operations.

  (1) As the essential device of the flexible adjustment, the micro-impact hummers (MIHs) made by the piezoelectric actuators were newly developed, and were installed into the 2 dimensional NC positioning table. By using this device, the experiments on the automatic micro adjustment of the positional and orientational deviation for the bolt-fastened component were done. The results of the experiments showed that the developed device could stably adjust the position and orientation of the jig-component with the initial deviation of 30 mum and 0.001 rad into the allowable deviation zone of 5 mum and 0.0002 rad.(2) For the purpose on the optimal tolerances synthesis of the mechanical assembly, a computer aided system for the 3D tolerance synthesis system was developed. The assembly was represented by solid model, and dimensional and geometrical tolerances were formulated as a set of inequalities. Differential coordinate transformation and linear programming were used to analyze the dimensional and geometrical tolerance stack-up. The cost data base descried the relation among form featured, tolerance range, machining and set-up costs. Tolerance synthesis was formulated as the combinational optimization problem under the stack-up conditions. Genetic Algorithm was applied to solve these problems. The coding method and genetic operators were discussed. The algorithm was evaluated through the tolerance synthesis for the gear box. It was confirmed that the proposed GA based tolerance synthesis method could find the optimum tolerance allocation plan for a rational period.

  The results obtained are summarized as follows: (1) The surface roughness(R) is exponentially decreased with the increase of the number of polishing operation(N) and can be obtained quantitatively according to the following equation: R = (R_0-Re)exp(-aN) + Re where R_0 is surface roughness before polishing, Re is final surface roughness and a is exponential constant factor. (2) The curve of the stock removal vs the polishing times is expressed approximately with two lines and the intersection of the two lines corresponds to the critical polishing times in which the surface can be almost finished. (3) The developed automated polishing tool which is attached to the spindle of NC machine tool makes it possible to finish the surface like a skilled machinist by handwork. (4) Using new polishing parameter(N/(f/n)) consisting of the three factors of wheel revolution(n), feed rate(f) and polishing times(N), the surface roughness and the stock removal can be dealt with quantitatively regardless of polishing conditions.

  The machining simulation technique is very important for computer aided manufacturing system and NC data verification. If we can forecast the machining phenomena, for example, cutter collision, cutter removal shape, removed volume and cutting force by using simulation techniques, a more high level computer controlled machining system can be realized. Some research on machining simulation based on conventional geometric modeling techniques such as CSG or Breps have already been done.
  However, these approaches were time consuming and complex because of the massive set operations between workpiece and cutting tool. Difficulty in defining cutter swept volume, and restricted within their specific application. To solve these problems, we introduce the voxel representation of geometric model and logical set operation on voxel space. The machining simulation technique based on the voxel representation of geometric models makes it possible to recognize not only cutter collision but also various status among cutting tool, workpiece and fixturing device, by the uniform data representation and simple logical bitwise operations.
