近年，構造物の検査や管理において様々な局面で3次元点群計測が取り入れられているが，レーザスキャナが比較的大規模な構造物を対象としており，点群データを用いた検査手法が確立していない，狭隘なパイプラインの内壁検査への適用には課題がある．本研究では小型で安価なRGB-Dカメラを用いて，パイプラインの管内形状を計測しその変形量を算出する技術を提案する．通常パイプライン管内の断面形状やその変形量はゲージを当てた局所でしか計測しない．本研究では3次元計測により得られた管内形状の点群データを直接処理し，点群分布の粗密に関わらず自動的に断面データを抽出し，たわみ量を算出する．600mmφのパイプを用いた実験により，直ちに補修・交換が必要とされる5%程度のたわみを網羅的に安定して検出可能であることを確認した．

レーザスキャナは詳細で広範囲の3次元情報を取得できる一方，現実的な作業量で実用的なデータを得るには計測位置の選択が難しく，専門作業者の経験に頼るところが大きい．我々は，現地で撮影した写真からSFM（Structure from Motion）を使って復元した3次元情報をもとに各地点での見通しを考慮し，数理計画法によりスキャン計画を最適化する手法を開発している．SFMの出力が疎な3次元データであることから，これまでは手動でのデータ補間とモデリング作業を要していたのに対し，本稿ではMVS（multi-view stereo）により系統的で数理計画法に適した3次元モデル化プロセスを実現する．さらに，スキャンの追加や，局所部分の重点的な計測など，現場で発生する運用ニーズに対応できる最適なスキャン計画の立案方法を示し，奈良県大和郡山市の郡山城での石垣調査における計測にて，その有効性を検証した．

Previously we proposed an eccentric figure-eight coil that can cause threshold stimulation in the brain at lower driving currents. In this study, we performed numerical simulations and magnetic stimulations to healthy subjects for evaluating the advantages of the eccentric coil. The simulations were performed using a simplified spherical brain model and a realistic human brain model. We found that the eccentric coil required a driving current intensity of approximately 18% less than that required by the concentric coil to cause comparable eddy current densities within the brain. The eddy current localization of the eccentric coil was slightly higher than that of the concentric coil. A prototype eccentric coil was designed and fabricated. Instead of winding a wire around a bobbin, we cut eccentric-spiral slits on the insulator cases, and a wire was woven through the slits. The coils were used to deliver magnetic stimulation to healthy subjects; among our results, we found that the current slew rate corresponding to motor threshold values for the concentric and eccentric coils were 86 and 78A/mu s, respectively. The results indicate that the eccentric coil consistently requires a lower driving current to reach the motor threshold than the concentric coil. Future development of compact magnetic stimulators will enable the treatment of some intractable neurological diseases at home. Bioelectromagnetics. 35:55-65, 2015. (c) 2014 Wiley Periodicals, Inc.

This paper proposes an AR (augmented reality) interface for on-site use in an archaeological project. We have already been developing a web-based 3D archiving system for supporting the diverse specialties and nationalities needed for carrying out the survey and restoration work of the archaeological project. Our 3D archiving system is designed for the spontaneous updating and sharing of information on findings in order to better enable frequent discussions, through a 3D virtual copy of the field site that a user can visit, explore, and embed information into, over the Internet. Here we present an AR user interface to enhance access from mobile devices at the actual site to the archiving system. Using SFM (structure from motion) and solving the Perspective-n-Point (PnP) problem, a photo taken at the site can be stably matched to the pre-registered photo sets in the archiving system and the archived information is automatically overlaid on the photo, just in the same manner as exploring the virtual version of the site on desktop PCs. Our implementation effectively works on an on-going project in Saqqara, Egypt.

This paper addresses management issues in a multifaceted archaeological project, using a web-based archive system with a 3D user interface. The diverse specialties needed for driving the surveys and restoration work at the archaeological project and the fact that the team is composed of people of different nations means work may progress asynchronously, which can result in a failure to maintain the communications needed to ensure that everyone and everything is kept up to date. A mechanism is desirable for the spontaneous updating, accumulating and sharing of information on findings to better enable frequent discussions. The proposed system generates a 3D virtual copy of the field site that a user may explore and embed information by making an association with a physical object at a site over the Internet. Here we present the implementation scheme of the proposed system based on an on-going project at Mastaba Idout in Saqqara, Egypt.

Studies on the great pyramid of King Khufu (2509-2483 BCE ±25) in Egypt are numerous, but only a few surveys, which are the basis of any hypotheses on the construction of a pyramid, have been conducted. In particular, since no observation of the core of the pyramid has been made, theories about the structure are still hypothetical. In 2013, a Japanese TV production company had the opportunity to climb the northeast corner of the pyramid to shoot a crevice that led to an open space (named 'cave') inside the pyramid, located about 80m from the ground. The authors are fortunate to be allowed to use this video footage for academic research. We employed a 'structure from motion' (SfM) technique using Microsoft Photosynth to reconstruct the 3D point cloud of the surface of the cave. Twenty minutes of footage was split into thirty thousand image frames, out of which we selected three hundred images shot using several smooth motions of the camera and used these for the SfM process. SfM tracks the 'feature points' in the image sequence to estimate the camera motion and then triangulates these feature points to produce the point clouds. As a result, the static feature points from the overall surface of the cave were effectively collected and reconstructed as point clouds, whereas inconsistent points from a moving person are automatically eliminated through the SfM process. Thus we have produced, albeit in a small area, the first record of the actual structure of the great pyramid's core. The production of a 3D model from existing video footage is a rather new methodology in the field of archaeology. This set of techniques can be applied to not only academic investigation but also to the restoration and conservation of damaged heritage and artifacts. © 2013 IEEE.

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive method for treating various neurological and psychiatric disorders. With the growing demands of neuropathic pain patients and their increasing numbers, rTMS treatment tools are becoming more necessary. rTMS uses electromagnetic induction to induce weak electric currents by rapidly changing the magnetic field. Targeting the electric current to a specific part of the brain is one treatment for pain relief. This paper focuses on treatment for neuropathic pain caused by a lesion or disease of the central or peripheral nervous system, including stroke, trauma, or surgery. However, the current style of rTMS treatment is still developing and is so technically specialized that only a limited number of hospitals and only a handful of specialists can provide this therapy. The existing rTMS systems use an optical markerbased 3D sensing technique that positions the stimulation coil to target the small region of interest in the brain through coregistration with pre-scanned MRI data. This system requires the patient to be immobilized on a bed. The optical markers for 3D sensing are placed on the patient's head to maintain accurate positioning. We propose a constraints-free, markerless rTMS system, which employs ego-motion, a computation technique to estimate relative 3D motion of a camera to what the camera sees. We use a ToF sensor as a camera, which is capble of capturing shape information from a single viewpoint instantly. The markerless target spot is based on the shape features of the patient's face. This paper shows the process of a prototype system and its potential for achieving an easy-to-handle system framework. © 2013 IEEE.

難治性疼痛は，薬物治療で効果を認められない場合が多く，糖尿病や脳卒中など，その原因も多岐にわたる．脳や脊髄に直接電気刺激を送る方法は侵襲的で敬遠されがちである一方，経頭蓋磁気刺激は，体外から磁気刺激を行うため，非侵襲的処置で除痛効果が得られ，期待されている．この治療には，大脳一次運動野の最適刺激位置を患者ごとに特定し，これに磁場が当たるようにコイルを位置合わせする必要があり，専門医が頭部MRIを参照しながら治療を行う．現行の位置合わせには，反射マーカを使った汎用の3次元位置計測システムが多用されることから，診察のたびに，医師はマーカの付設と初期位置合わせの煩雑な作業を強いられ，患者は身動きが許されない．本研究では，反射マーカの代わりに，画像情報を積極的に利用した単一のステレオカメラで，異なる3次元計測法を併用することにより，患者，MRI，コイルの三者の実時間位置合わせを行う手法を提案する．提案手法により，初期位置合わせを自動化し，患者に対して非拘束な状態で磁気刺激治療に必要な位置決めが可能であることを，実装と実験に基づいて確認した．

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive method for treating various neurological and psychiatric disorders. This paper focuses on a technical as-pect of this treatment method for neuropathic pain that can be caused by a lesion or disease of the central or peripheral nervous system, including stroke, trauma or surgical operation. rTMS uses electromagnetic induction to induce weak electric currents by rapidly changing the magnetic field. Targeting a specific part of the brain to locate the magnetic field works as a treatment for pain relief. This is the reason why the current style of rTMS treatment is still developing and is so technically specialized that only a limited number of hospitals and only a handful of special-ists can provide this therapy. The existing systems of rTMS are based on an optical maker-based 3-dimensional (3D) sensing technique for positioning the stimulation coil to target the small spot in the region of interest in the brain, and for referring pre-scanned MRI data to check the target position. Furthermore, the existing systems require the patient to be fixed on a bed in which optical markers for 3D sensing are placed during the treatment to maintain positioning precision. With the growing demands of neuropathic pain patients and their increasing numbers, new approaches and systems to achieve more supportive and easy-to-handle navigation have been proposed lately for rTMS treat-ment. This paper proposes a quantitative index for localization precision, considering an uncertainty measure. Uncertainty is technically defined as a parameter, associated with the result of a measurement that characterizes the dispersion of the values that could reasonably be attributed to the measurement. This paper shows a detailed example of the uncertainty derivation for rTMS treatment, based on trial tasks for searching the spots on the brain that cause muscle twitch. © 2012 IEEE.

We are developing stimulation coil navigation systems for home use of repetitive transcranial magnetic stimulation (rTMS). rTMS is effective for intractable diseases of the nervous system. However, the effects of rTMS last only for several hours, requiring a continuing daily rTMS therapies in a nearby clinic. A magnetic navigation system, the present system for fulfilling such needs, uses downsized, lightweight, low-cost magnetic sensors with datasets relating the magnetic field to the 3D position of the stimulation coil instead of the complicated handling and operation of large-scale and expensive devices or systems like a 3D position-measurement device. This system has been modified for home use and is easily available to non-medical staff. However, in a hospital, a large number of datasets, at least 500, is required, so collecting datasets might be a burden for the physician. To solve this problem, this paper proposes a method for extracting the necessary datasets for navigation. In the proposed method, many more datasets, which can handle any shape of a patient's head, are prepared in advance. The physician then collects only a few samples in the hospital. The system extracts the remaining datasets necessary for navigation by applying geometric model approximations like Delaunay triangulation or the ellipsoid model to the data for these samples. We evaluate the efficiency of the proposed method by a simulation of extracting datasets and navigating using a head model. The proposed method reduces the number of datasets collected by physicians from 500 to 10, thus reducing physicians' burdens. © 2012 IEEE.

Hospital information systems (HIS) have turned a hospital into a gigantic computer with huge computational power, huge storage, and wired/wireless local area network. On the other hand, a modern medical device, such as echograph, is a computer system with several functional units connected by an internal network named a bus. Therefore, we can embed such a medical device into the HIS by simply replacing the bus with the local area network. This paper designed and developed two embedded systems, a ubiquitous echograph system, and a networked digital camera. Evaluations of the developed systems clearly show that the proposed approach, embedding existing clinical systems into HIS, drastically changes productivity in the clinical field. Once a clinical system becomes a pluggable unit for a gigantic computer system, HIS, the combination of multiple embedded systems with application software designed under deep consideration about clinical processes may lead to the emergence of disruptive innovation in the clinical field. © 1997-2012 IEEE.

Repetitive Transcranial Magnetic Stimulation (rTMS) is effective for intractable diseases of the nervous system. As the effects of rTMS last only several hours, rTMS therapies need to be continued daily. Under present circumstances, it is difficult to use rTMS in patients' home, because only experienced physicians in limited hospitals can use the expensive and complicated rTMS system. Therefore, we developed a magnetic navigation system for home use of rTMS. The proposed system uses inexpensive and small magnetic sensors; hence it is suitable for home use. By using the proposed method, even people who have no medical knowledge and technique can easily navigate the coil to the optimal position preliminarily specified by expert physicians. Our system needs to collect some dataset which consists of magnetic field and the corresponding position of the coil at the patients' initial visit. Since it is bothersome to collect a large number of dataset, we reduced the dataset by approximation using multi-regression analysis.

Augmented Reality (AR) is a technique that synthesizes and displays virtual objects such as CG in images of real environments. It is important to harmonize real environment with CG and to render the harmonized scene. In this research, we propose a method for rendering virtual objects by using Image-based Lighting (IBL) that uses polyhedral subdivision in AR. We confirmed that hierarchical light source map constructed by polyhedral subdivision reduces the computation cost and maintains the effect of IBL.

Structured light is used for measuring 3D shape efficiently by active stereo methods. The measurement resolution of this method depends on not only the interval of structured light but also the pattern direction. In this paper, we propose a method for acquiring homogeneous data by structured light measurements. The method uses multiple structured lights with different directions and then registers the data based on measurement density over the object surface. Our experimental results showed that the proposed method is capable of reproducing 3D shape of measurement objects more precisely.

Ultrasonic diagnosis requires substantial experiences for both acquiring and reading echography. This paper describes a novel method for synthesizing ultrasound image with artifacts according to user's probe manipulation. The proposed method is a sample-based approach that stores pre-captured real echo images as a volume data set in which each voxel has multi-directional values. Output echography is synthesized by interpolating voxel values, considering spatial arrangement and directivity of the voxel values. Experimental results demonstrated spatially seamless echography synthesis and characteristic artifacts with various probe postures.

Colors in nature can be classified into two categories: pigment colors and structural colors. Structural colors, which are caused by optical path differences of reflected rays in microstructures, change depending on viewing angle and lighting conditions. In the present paper, we propose a generic approach for rendering structural colors in real-time. The proposed method uses optical path differences as common parameters to allow unified treatment of various types of microstructures, such as thin films, multilayer films, and diffraction gratings. To achieve real-time rendering, we store pre-computed information related to specific microstructure and lighting conditions on several kinds of textures. The textures are used as a look-up table in the rendering process. The proposed method can be applied to objects that have arbitrary shape and enables rendering from any viewing direction and under any lighting conditions.

The motion capture technique is gathering more and more attention because of its powerful potential for providing life-like motions in computer graphics (CG) animation via sample-based motion creating techniques. Since motion data is multi-dimensional and spatio-temporal data that is difficult to edit as desired, an effective scheme for reusing captured motion sets to create new motion is advantageous. Reusing a motion data set requires effective browsing and extraction techniques that enable the user to look up and capture the relations among the motion contents in the motion data set. We propose a new framework for a motion editing tool by focusing on the connectivity between motions and utilizing it as a filter to extract the desired motion contents from a motion database. The proposed system uses a tree structure for expressing possible connective motion paths in the motion database. The motion connective tree can be a useful user interface to browse and select a motion scenario by exploring the existing motion data sets in the database. Our prototype system demonstrates an easy-tounderstand interface to explore and quickly edit a motion data set by selecting icons of the motion tree nodes. © 2008 IEEE.

This paper describes a fabrication scheme for integrating an optical fiber-delivered catheter for ultrasound (US) imaging. In this catheter, pulsed laser is focused and guided into a tapered optical fiber. The laser passes through the fiber and is refocused to generate laser-induced breakdown (LIB), which emits spherical pulsed US wave. The reflected US waves are received with a hydrophone array to reconstruct 3D images with synthetic aperture method. We examined the probability of LIB generation relative to pulsed energy level for stably producing US pulses and clarified a suitable specification for a laser delivering fiber. Proto-type catheter demonstrated real-time 3D imaging, in which LIB is continuously generated on the tip of the catheter and frontal situation is captured in 3D images in realtime process.

本論文では，VR 空間における作業対象物体と操作者間の円滑な相互作用を実現するために，操作者の姿勢に基づき指示方向を推定する手法について提案する．提案手法では，指示方向を，操作者の複数の身体部位と人差し指の先端を結ぶ方向の重み付け平均として表現する．この重みを収束計算で求めることにより，個人・方向・距離によって生じる差を吸収し，指差し方向を推定することを可能にする．実験から，提案手法が操作者の意図している指示方向を約3 度の精度で推定でき，VR 空間での対象物体の直接操作に有効であることが示された．We propose the estimation method for pointing direction from users' posture to establish smooth interaction between users and virtual objects in virtual reality space. We describe the pointing direction as weighted average of reference directions which connect between some parts of user's body and the fingertip of index finger. The weights, which depend on individuals, direction and distance, are estimated through repetitive calculation. The experiments reveal that the proposed method can estimate the direction which users intend to point accurately.

In manufacturing factories, it is important to reduce costs and to ensure product quality in suffer market competition. With the massive retirement of expert engineers in aging society, an effective training/education scheme for new workers is desired. However, cell production system is widely used lately and each worker is supposed to do every step of the process and thus the worker should learn more and more kinds of manufacturing skills and process. It is also desired that fresh workers can learn the skills by themselves, however, transferring skills is a very difficult issue. Learning by print-based manuals is not effective, because it is not easy to understand how to operate 3D objects and how the process transition goes from 2D documents. Besides, flipping the pages to find the information during the work is troublesome. In this research, a new training system is built with a movable head-up display, which can be adapted to actual workspaces and allows the user to access the digitized guidance contents with semitransparent touch-sensitive screen. The effectiveness is experimentally shown by applying the proposed system for some tasks to make "origami", a kind of skillful paper craft works. © 2007 IEEE.

The proposed method's use of optical path differences as common parameters enables unified treatment of various types of microscopic structures and representation by textures that store optical path differences, which can speed up rendering. The proposed method can be applied to object of arbitrary shapes and enables rendering from random viewing angles and lighting conditions in real time.

The proposed system consists of a camera with a fish-eye lens and a cylinder whose inside is coated by a silver reflective layer. A target object is placed inside the cylinder and an image is captured by the camera from right above. The captured image includes sets of points that are observed from multiple viewpoints: one is observed directly, and the other is observed via the mirror. Therefore, the whole shape of the object can be measured using stereo vision in a single shot. An actual experimental situation was simulated and the three-dimensional shape of the target object was measured using the simulated image. In addition, a prototype system was implemented and the shape of the real objects were measured. The results have demonstrated that the proposed method is effective for measuring the whole three-dimensional shape.

The documents become more legible by doing the annotation. There are some systems that support annotating or reading digital document, but they cannot be applied to physically printed-paper documents. Moreover we are not allowed to write notes in vintage books or books of a library. This paper proposes the system of "Digital Bookrest", which adds the electronic property to the physically printed-papers. The components of the proposed system are a digital camera, a video projector and a pen-shape device with LED. The system estimates positions of paper documents and annotated points in the captured image, and overlays annotations onto the real paper document using a video projector. The prototype system was implemented, and experiments are performed to confirm the availability.

This paper presents a new scheme for synthesizing hand motion to grasp various objects. Hand motion has a variety of expression with its high degrees of freedom and the functional motions are especially complex and difficult to synthesize. This paper focuses on a fact that actual grasp motion varies depending on the features of the object including its size and shape, which give important clues for reproducing a proper hand motion to manipulate them. Based on this idea, we propose a scheme to sample grasp motions and synthesize the whole hand motion including approach to the object, preparation of the hand shape and grab motion. Synthesized animation demonstrated a potential for easily designing functional motions for hand animation.

Paracentesis is a common operation for pain clinics and spinal anesthetics administration and requires empirical training and flexible skills to cope with the various cases of individual patients. We propose a method of measuring and visualizing three-dimensional vertebra shapes for assisting anesthesiologists, by an ultrasound imaging technique that is prevalent in many hospitals and has no harmful risks to the human body. The proposed system enables anesthesiologists to investigate vertebra shapes by freehand probing. Three-dimensional reconstruction and graphical rendering can be performed by monitoring the motion of the ultrasound probe and registering the scanned echography into the identical three-dimensional space. Considering the echography imaging features, volume rendering of hard tissue surfaces is achieved and interactive measurement is possible. This paper describes the practicability of the proposed method based on experimental measurement of both phantom and real lumbar vertebre and sacra.

This paper describes an ultrasound (US) catheter using laser induced breakdown (LIB) phenomenon and 3D imaging with the catheter. In this catheter, laser focused with an optical lens is introduced into a tapered optical fiber. The laser passed through the fiber is refocused with lenses to generate LIB inside of a small balloon filled with D2O and spherical and pulsed US transmitted from LIB. The reflected wave was received at hydrophones and 3D images were reconstructed with synthetic aperture method. Using this catheter, we made the experiments of the imaging of an object in motion. We succeeded in presenting 3D dynamic image with the frame rate of about 5 frame/sec. © 2004, The Institute of Electrical Engineers of Japan. All rights reserved.

This paper presents a new framework for interactive Augmented Reality(1) (AR) and Mixed Reality(2) (MR) representation using both visible and invisible projection onto physical target objects. Projection-based approach for constructing AR/MR uses physical objects such as walls, books, plaster ornaments and whatever the computer generated contents can be optically projected onto, namely, projection makes it possible to use real objects as displays. What we demonstrate in this study is to employ near-infrared pattern projection for triangulation so that scanning and updating the geometry data of the object is automatically performed in background process; thus parallel processing to provide AR/MR representation can be achieved according to dynamic physical geometry changes.

Real-time rendering of realistic motion of fluids is a method that immerses a player into an interactive application such as computer games. Interaction of fluids with rigid bodies is important because fluids and rigid bodies move influencing each other. Fluid simulation based on Computational Fluid Dynamics (CFD) is useful for rendering a visually plausible behaviour of fluids. However, due to the high computational cost of CFD, real-time rendering of fluids needs a fast simulation. This paper describes the particle-based fluid simulation based on Smoothed Particle Hydrodynamics which includes interactions between fluids and rigid bodies, its fast implementation, and the manner of rendering a realistic water surface with optical phenomena such as reflection, refraction, and the Fresnel effect. The proposed method enables real-time animation of water with rigid body interaction.

This paper proposes a method of synthesis of lighting environment based on the atmospheric conditions for creating highly realistic outdoor scenes. The optical atmospheric model takes into account the effects of Rayleigh and of Mie scattering as a part of the physical model. Clouds, which enhance the reality effect of rendered images, are extracted and composed onto the spherical light image. A CIE XYZV color model is used as a visual modelto create scotopic vision. A comparison of a calculated and a measured spherical light image showed that using the proposed method can reproduce a proper lighting environment under any atmospheric conditions.

A new approach for enhancing the resolution capability of an ultrasound transducer in both axial and lateral directions is presented. A functionally graded piezoelectric composite of 1–3 connectivity is newly devised and applied to a weighted conical transducer. In this piezocomposite material, an electric field for wave excitation is effectively graded in the thickness direction, and this makes it possible to launch an almost single-pulse ultrasonic wave. Because of flexibility, this composite material can be formed easily into a conical shape and enhances the time resolution of the conical transducer that possesses good lateral resolution over a large depth. The experimental results obtained for the fabricated transducer show the capability of launching a short ultrasonic pulse and creating a focused field over a large depth.

We have proposed the visual and haptic interface for the tele-echo system where ultrasound (US) probing can be instructed from a diagnostic to measurement site via network. In the measurement site, the surface of a patient body was captured with a CCD camera and the shape of patient was measured using the triangulation. In the diagnostic site, three dimensional image of a patient was reconstructed and a medical doctor could touch the virtual patient body with a haptic device. The position, orientation and tilt of a US probe was transmitted from the diagnostic to the measurement site with our previous proposed mark, called 'Web-Mark' and the mark was projected on the patient directly. The experimental results demonstrated that the proposed system enables to obtain US images, long axis and apex image in the shorter time as compared with the system using two dimensional information of the patient only.

The Blind cannot detect some obstacles with a cane that is the most successful and widely used travel aid. This paper describes E-cane designed for the Blind to support their traveling by detecting such obstacles. Foregoing electric travel aids do not tell surroundings or obstacles, but just convert obtained data into certain signals such as vibration. E-cane presumes surroundings from obtained data and notify interpretation. This situation presumption mechanism understands surroundings as combinations of walls and floors. This wall/floor-strategy is designed for fast and robust processing. Experiment results show that the proposed system detects and notifies surroundings properly, therefore the Blind can walk more safely.

This paper describes fundamental investigations for an ultrasound catheter using laser-induced breakdown (LIB). Laser energy was transmitted through an optical fiber and lenses and focused to generate LIB in a water bath. In order to reduce laser energy for LIB generation, heavy water (D2O) was used to fill in the water bath instead of H2O. In the experiments, the ultrasound signal generated from LIB was detected with a needle hydrophone. After amplification and digitization, the signal was transferred to a personal computer (PC) and then off-line filtered. The filtered signal shows that the ultrasound signals have several peaks. The first peak is the signal directly detected with the hydrophone, while the rest of the peaks are those reflected at the water front or bath walls, indicating that the ultrasound has low directivity. We concluded that the proposed catheter is feasible for obtaining the frontal image of a blood vessel.

Recently, ITS (Intelligent Transport Systems) for pedestrians is paid much attention and there are many related researches, out of which, Human-Navigation System is the most actively studied. However, pedestrian traffic information is not really utilized. When walking in town, for instance, we often want to avoid pedestrians’ congestion, particularly for handicapped and higher age people. If the pedestrian traffic information is available as a real-time map for each pedestrian, it can provide variety of effective services for ITS. Storing the statistics data is also useful not only for individuals’ scheduling but the marketing business. This paper proposes the system architecture that allows to monitor the pedestrian traffic by distributed camera terminals and to map the gathered information onto a display server via network. We also propose an effective method to detect traffic information using image processing with wide-angle camera and show some experimental results.

In this paper, we propose a new framework of ultrasonic (US) three-dimensional (3D) imaging, introducing laser-induced breakdown (LIB) as an acoustic source. LIB is a phenomenon in which a substance is transformed to a plasma by a pulsed laser beam. LIB explosively emits a variety of energies such as heat, light and sound which also includes pulsed ultrasound. Emitted US waves have suitable characteristics for US 3D imaging in terms of low directivity, enabling a wide view and sharply pulsed waves. Utilizing these characteristics, we attempt to apply the synthetic aperture method for frontal 3D imaging in a real-time process. Experimental results show that even sparsely arrayed sensors allow a wider frontal view than that allowed in the case using existing transducers.

This paper describes a new approach for modeling the human hand by considering the dynamics and the natural constraints of the motion and the shape of hands. This hand model consists of a dynamic model and a surface model. The dynamic model is used to generate the posture of a hand. We show that the natural hand posture can be generated even when only a few hand parameters are available. The surface model is used to generate the hand shape based on the posture given by the dynamic model. The surface model is built based on the digitized three-dimensional shape of a real hand.

The proposed system consists of a camera with a fish-eye lens and a cylinder whose inside is coated by a silver reflective layer. A target object is placed inside the cylinder and an image is captured by the camera from right above. The captured image includes sets of points that are observed from multiple viewpoints: one is observed directly, and the other is observed via the mirror. Therefore, the whole shape of the object can be measured using stereo vision in a single shot. An actual experimental situation was simulated and the three-dimensional shape of the target object was measured using the simulated image. In addition, a prototype system was implemented and the shape of the real objects were measured. The results have demonstrated that the proposed method is effective for measuring the whole three-dimensional shape.

This paper proposes a suitable technique for capturing sports motions. Optical motion capture systems have an advantage of less interference to moving targets, and therefore, it is often used for digitizing human actions. However, how to arrange and attach the markers on the body surface are a key issue. We pointed out two problems of conventional marker alignment. One is that the joint surface where a marker attached on is quite flexible and it might cause a large gap between the marker and the joint position during motion. The other is that measuring each joint as a point position does not provide precise axial rotation. The rotation around major axis is important for all sports forms including throwing, kicking and so forth. In this paper we propose a new method for measuring each joint point as a cross point of major axes of adjacent segments and the rotation around major axis, using optical circular-ring markers. Circular-ring marker has painted stripes along the body segment and can be used by wrapping it around a segment. The orientation of major axis and the rotation around it can be measured by extracting the stripes. The proposed approach is free from interference to the body motion and expected to be effective for sports motion capturing.

自然界の色は色素色と構造色に大別することができる。色素色は色素による発色であるのに対し、構造色は波長以下の微細構造に起因する光学現象による発色であり、視点位置や照明条件により見え方が大きく変化するという特徴をもつ。本研究では構造色を生み出す光路差に着目し、汎用的な構造色のレンダリング手法を提案する。本手法では微細構造を光路差や反射強度などを格納したテクスチャ表現によりモデル化することで、リアルタイムでのレンダリングを実現している。Colors in nature can be divided in two categories: colors which originate in pigments (coloring matter) and structural colors caused by optical phenomena at the level of microscopic structures. The structural colors have a unique characteristic that the color changes according to viewing directions and lighting conditions. This research focuses on optical path differences and proposes a generic rendering method for structural colors. This method models the microscopic structure by using textures storing physical parameters. The proposed model can be applied to various types of structural colors and is suitable for real time rendering.

ボールスポーツの本質はボールの行方を観察することである．戦術分析においても，従来から，競技の様子をビデオカメラで撮影し，その映像から計測した時系列のボールの3次元位置データを利用することが行なわれている．一般にボールの3次元位置計測はステレオ法が用いられるが，ボールは高速移動するため，ブレの無い（シャッタースピードが速い）同期の取れた高速レートの多視点映像が必要である．そこで，逆にシャッタースピードを遅くして映像にボールの軌跡を故意に残し，多視点から撮影された軌跡を空間に投影して共通部分を計算することで，3次元軌跡を求める手法を提案する．本手法によりカメラ間の同期を取らなくてもボールの3次元位置が計測可能となるだけでなく，フレーム間のボールの3次元軌跡も決定可能になる．つまりステレオ法では時間的に離散な3次元位置しか計測できなかったが，本手法では連続な3次元軌跡が計測可能である．このようにして求めたボールの3次元軌跡には時間情報が付加されていないが，映像のフレームが切り替わる瞬間のボールの位置から，時間情報を付加することもできる．本稿では，本手法の詳細を説明した後，実際に本手法を卓球に適用した結果を示し，その考察を行なう．This paper proposes a new method of measuring a 3D trajectory of ball. Our proposed method does not need high-speed video cameras and synchronized video cameras to measure the 3D ball trajectory, and it enables to measure a continuous trajectory between shutter timings.

The estimated 3D trajectory does not- have time stamp information. The time stamp information is given according to a correspondence between 3D trajectory and the position of ball in images when video frames are switched.

This research especially focuses on indoor circumstances such as shopping moles and station buildings where the passage traffic changes dynamically and the physical space is limited. Our approach requires limited number of wide-angle cameras that are capable of covering large viewing area even from the ceiling of the narrow passage. Experimental results showed effective performance for grabbing the situation of the pedestrians over time.

In this paper, we propose new measurement technique of whole three dimensional shape for small moving objects. The proposed measurement system is very simple structure with the use of a CCD camera that installed a fish-eye lens and a cylinder that coating mirror inside. The CCD camera is set on the top side of the cylinder, and its optical axis is set to the center of cylinder. A captured image includes two types information. One is direct view of the target, the other is reflected view. These two information are used for measuring the shape of target by means of stereo matching. This proposed method can acquire the shape of target using only single image so we can obtaine the three dimensional shape with the moving with the use of image sequence.

We propose a novel method for measuring a whole three-dimensional shape of an object with a simple structured system. The proposed system consists of a single CCD camera and a cylindrical mirror. A target object is placed inside the cylindrical mirror and an image is captured by the camera from above. There are two or more points that have the same origin in the captured image: one is observed directly, and the other is observed via the mirror. This situation means that a point is observed by a real camera and virtual cameras at the same time. Therefore, the three-dimensional shape of the object can be obtained using stereo vision. We simulated an actual experimental situation and measured the three-dimensional shape of the object from the simulated image, and the results have demonstrated that the proposed method is useful for measuring the whole three-dimensional shape.

We propose a new filtering method to achieve realtime computer graphics of precise 3D shapes. By recent 3D scanning systems, it becomes possible to measure 3D shape of objects with high precision. Normally these scanners sample 3D positions of points (point clouds) on the surface of objects so that we must build polygon model before synthesizing surface-rendered computer graphics. Increase of measurement data by progress of recent 3D scanning systems, however, makes cost of creation of polygon model higher. Thus non-surface rendering including point rendering techniques are focused on. To achieve high-quality point rendering of objects scanned by such 3D scanners, we must perform some kind of filtering on obtained data since point data obtained by 3D scanner is often irregularly formed and also has non-uniform density. We have achieved one of such filtering by applying resampling and frequency analysis on point clouds.

建築物やインテリアのデザインにおいては,対象となるオブジェクトの設計のみならず、周囲の環境を含めた概観のシミュレーションの道具として3次元CGが利用されている。しかし、実在するシーンや屋内環境にCGのオブジェクトを配置して、レイアウトや色調などを確かめるには、実在環境のモデリングが重要であり、また難点となる。本研究では,実在する環境シーンの上にレイアウト対象となるCGオブジェクトとを視覚的に融合するMixed Realityの技術を積極的に利用することで,周囲環境のモデリングを行なうことなく対話的にレンダリングを可能にするフレームワークを提案する.鏡面球と2次元コードとを有する立体マーカを対象となる実環境に配置することにより,現場での空間配置や光源環境を、ユーザのカメラ視点から読み取り、実時間処理によってMRシーンとして提示するものである。実験では、室内でマーカを並べてゆくことにより対話的シーンの色合いや空間配置を確認しながらCGオブジェクトをレイアウトすることができ,有効性が確認された。

For presenting virtual objects in a real space, mixed reality (MR) technique is very effective to simulate an overview of a scenery. In interior design, for instance, the coordinates of the arrangements and the colours of the items need to be determined based on various layout plans. We propose a new framework for interactively arranging and rendering virtual objects in real space by manipulating physical 3D markers. A 3D marker consists of 2D codes and a spherical mirror for acquiring both geometric and photometric conditions by single camera instantaneously. Experimental results showed that the proposed approach is effective for providing appropriate geometry and local lighting conditions to present each virtual object in a simple system. The proposed system allows the user to experiment arranging of virtual furniture and verify the created scene which is visually consistent with the physical space.

Modulation of JSL (Japanese Sign Language) is represented with many components such as the hand motion, the facial expression, and so on. To communicate the proper meaning of sentences, modulation is one of the integral elements for JSL. Current Japanese-to-JSL translation systems use CG (Computer Graphics) animation, called sign animation, to represent Sign Language. Sign animation without modulation is mere mechanical expression for the hearing-impaired person. This report focuses on modulation represented by hand motion and creates more human-like animations by means of analyzing captured Sign Language. A preliminary survey showed that modulation by adjectives divides hand movements into three patterns. Extracting the adjective from sentences and changing hand movements by use of three patterns produce animations including modulation. Experimental results suggest that animations produced by the proposed method are a more natural and understandable expression for the hearing-impaired person.

近年,三次元形状計測装置により物体の形状を高精度に計測することが可能となった.これらから三次元点群の状態で物体表面の形状を得ることができ,従来は主にポリゴンモデルを用いたサーフェスレンダリングによって可視化が行われて来た.しかし,点の数が多くなるとポリゴンモデルの生成が高コストとなるため,ポイントレンダリングなどの非サーフェスレンダリングが注目されている.ポイントレンダリングを行う際には,点密度が一様であることが望ましいが,三次元形状計測装置から得られる点群データは,物体の形状や計測位置によっては,一般に得られる点の並びが不規則であり,また計測ノイズが混入することがあるために,単純なポイントレンダリングには適さない.さらに,異なる計測装置での計測結果を統合した異なる解像度の点群が混在するデータもポイントレンダリングには適さない.そこで本研究では,これらの点群データに対し,リサンプリングと周波数解析を施すことによって,ノイズに強く形状操作も可能な新たな点群モデルを構築する.

遠隔医療において、病理組織画像や細胞画像など、顕微鏡画像の伝送はその代表的なもののひとつであり、特に病理学、細胞診断学などの専門医の常勤しない一般病院においてその急務が問われると考えられる。本報告では、低コスト高速バス(∼400 Mbps)を備えたIEEE1394をデジタルビデオカメラ(DV)のインタフェースとして積極的に用いた遠隔病理診断システムを提案する。本システムはクライアント側がネットワークを介して直接カメラを制御することにより、対話的に伝送画像の解像度を切り替えなからホスト側の顕微鏡を操作し、病理診断を円滑に行うものである。低解像度画像(160×120/320×240)を高フレームレート(10∼24fps)で伝送することにより、顕微鏡操作をスムーズに行いROI (Region of Interest)を探しながら、高解像度画像(640×480)に切り替えて診断を行う。今後の、DVの解像度向上が本システムの実効性の増大に直結するものと期待される。

我々は、これまでヒトの手の形状と運動を自然に再現できる手の3次元モデルを試みてきた。このモデルは指などの関節の角度の設定によって手の基本的な姿勢を作り、手の骨格の形状と関節間の角度の情報を用いて皮膚表面の形状を決定するものである。しかしながら、手の姿勢を記述するための骨格モデル自由度に関しては、経験的なデザインに頼る部分が大きい。解剖学的見地からも十分連続的な運動学的データを用いた解析例はない。そこで、実際の手の指の3次元的な運動軌跡を得るために光学的なモーションキャプチャ技術を採用する。接触型デバイスとは異なり、手の動きに対して運動学的な仮定をおくこと無く、骨格モデルの自由度や運動をデザインするための手の運動データの獲得を試みた。Many articulated skeletal models for the hand have been proposed to create CG images. We also modeled a system that can generate natural hand postures automatically. But such skeletal models are described by a very simple way using just connections of rigid sticks and rotation joints. We introduce an optical motion capture technique to obtain motions of a real hand to model the basic skeletal model. We can design the degrees of freedom of the articulated structure of the hand and analyze the lifelike hand motion if we can obtain free motions of the hand without any kinematical constraints.
