This paper proposes a new method for foot pose estimation using a node of shoes and the planar ground in order to estimate diverse foot shapes from image sequences. We demonstrate foot motion tracking a scenario using the proposed algorithm for pose tracking of the human foot.
An objective of natural Human-Robot Interaction (HRI) is to enable humans to communicate with robots in the same manner humans do between themselves. This includes the use of natural gestures to support and expand the information that is exchanged in the spoken language. To achieve that, robots need robust gesture recognition systems to detect the non-verbal information that is sent to them by the...
An animated human model to be used in an electromagnetic simulation software, XFdtd, has been created using a 3D scanned surface of a real person combined with body movement data captured from a motion capture system. Investigations are carried out to verify the accuracy of the human body simulation for different mesh sizes. A study of the effect of body position over an on-body radio channel is also...
Displaying an agent-based simulation on an immersive virtual environment called CAVE (Cave Automatic Virtual Environment), a human expert is enabled to evaluate the simulation's dynamics from the same point of view as in real life — from a within perspective instead of a birds eye view. As this form of face validation is useful for many multiagent simulations, it should be possible to setup such a...
Advances in technology continue to make both hardware and software affordable and accessible; we have seen a rapid growth in computer vision and image processing applications. One area of interest in vision and image processing is automated identification of objects in real-time or recorded video streams and analysis of these identified objects. An important topic of research in this context is identification...
A parametric mannequin modeling technology based on feature is presented. Differing from traditional human modeling methods, this one involves a feature-based parametric design ideas, feature parameters are determined according to anthropometry; Additionally, a parametric deformation algorithm based on free-form deformation also have been introduced. The remarkable advantages of this technology are...
In recent years, virtual reality has emerged as a key technology for improving and streamlining design, programming, manufacturing and training processes. Based on experiences in the fields of space robotics, industrial manufacturing, multi-physics and virtual prototyping, "virtual testbeds" are currently being designed and implemented. Building on experiences gained in space robotics applications,...
Game system of treadmill based on video capture combines somatosensory technique which is hot now and professional exercise and body fitness together, providing a barrierless, ease experience of entertainment for people. This set of system captures running or jumping movement by a single camera, analyses the motion information to control the treadmill speed as well as the game role in the game engine...
Understanding of airflow in human airways is beneficial to medical field. Through the understanding, assessment on severity of airway disease and efficiency of medical inhalation drugs delivery can be assessed. For this purpose, an accurate and realistic human lung model is needed. With the variability in the outcomes based on both models notified, the reliability of the simplified models is questionable...
This paper proposes a particle filter based marker-less upper body motion capture system, capable of running in realtime. This system is designed for a humanoid robot application, and thus a monocular image sequence is used as input. We first set up a model of the human body, a sub-model which includes 11 Degrees of Freedom is used for the upper body tracking. Considering the realtime processing requirements,...
Digitization of real objects into 3D models is a rapidly expanding field, with ever increasing range of applications. The most interesting area of its application is in the creation of realistic 3D scenes, i.e. virtual reality. It can be used in the entertainment industry, design, architecture and scientific research. This paper provides a brief summary of current 3D scanning technologies, deals with...
In recent years, virtual assembly has become an effective technique for large equipment's maintainability analysis and verification. As an indispensable part in maintenance process simulation, motion control for virtual human still remains on low level based on key-frame or inverse kinematics, which in turn leads to an over complicated modeling process. Therefore, we propose an instruction-level motion...
At present, the sailorman have a little measure and time to do maintains training in real equipment and its failure effect is not very good. In allusion to this problem, this text founded virtual maintenance exploitation flat for sailormen in the need of maintenance training. The exploitation flat adopted the Aligned Axis Bounding Box and geometrical restriction method to solve the problems of collision...
It is a very challenging task to interactively build a realistic character model. In this paper, by introducing the stretching model and the vector differential adjustor, a character modeling method based on vector difference is proposed. With this method, firstly, a reference model, a vertical stretching model and a horizontal stretching model are constructed in accordance with the model structure...
Ergonomics is a systematic approach to study the relationship between the individuals, their tools and the work environment. While studying ergonomic considerations for dentists, it is observed that they suffer from musculoskeletal disorders (back pain) due to repetitive and awkward or stressful motions during their operation. This paper involves the literature survey on ergonomic design of dentist...
This paper analyses the characters of collected data from motion capture system. Afterwards, according to the movement principle of virtual human model in motion capture system and DELMIA, we provide a method to make it feasible for data reuse in virtual reality environment, and furthermore, some depiction will be given to show the application in different areas in brief.
Haptic perception and display of softness are important parts of the haptic display technique, which is currently the frontier in teleoperation systems and human-computer interaction. A portable softness display device is developed for this study. The device can quickly change the displayed stiffness by controlling the deformable length of the elastic element. Ideally, when a human operator's fingertip...
