미래의 정보전의 환경 하에서 병사들은 전투 상황 중에 각종 정보를 획득하고 이에 신속히 대응하는 하나의 체계(system)로서 전투 임무를 담당하게 될 것이며, 미래의 병사들은 각종 첨단 장비들을 신체에 부착하고 전투에 임하게 될 것이다. 첨단 디지털 기기들을 추가로 휴대하고도 기동성과 움직임에 저해 받지 않고, 오히려 정보력 상승으로 더 나은 전투력을 갖추기 위해 장치 구성품들을 의복에 내장시킨 '스마트 전투복'을 입을 것으로 생각된다. 본 연구는 정확한 모션 캡쳐 솔루션을 지원하는 VICON사의 Motion Capture System을 이용하여 동작에 따른 체표변화를 측정하고 해석하여 적절한 신체 부위에 기기를 배치함으로써 미래 전장에 적합한 스마트 전투복 디자인을 개발하는 것을 목표로 한다.

In this paper, we propose a new method of reconstructing the hand models for individuals, which include the link structure models, the homologous skin surface models and the homologous tetrahedral mesh models in a reference posture. As for the link structure model, the local coordinate system related to each link consists of the joint rotation center and the axes of joint rotation, which can be estimated based on the trajectories of optimal markers on the relative skin surface region of the subject obtained from the motion capture system. The skin surface model is defined as a three-dimensional triangular mesh, obtained by deforming a template mesh so as to fit the landmark vertices to the relative marker positions obtained motion capture system. In this process, anatomical dimensions for the subject, manually measured by a caliper, are also used as the deformation constraints.

This paper describes the implementation of wearable AHRS for an electromagnetic motion capture system that can trace and analyze human motion on the principal nine axes of inertial sensors. The module provides a three-dimensional (3D) attitude and heading angles combining MEMS gyroscopes, accelerometers, and magnetometers based on the extended Kalman filter, and transmits the motion data to the 3D simulation via Wi-Fi to realize the unrestrained movement in open spaces. In particular, the accelerometer in AHRS is supposed to measure only the acceleration of gravity, but when a sensor moves with an external linear acceleration, the estimated linear acceleration could compensate the accelerometer data in order to improve the precision of measuring gravity direction. In addition, when an AHRS is attached in an arbitrary position of the human body, the compensation of the axis of rotation could improve the accuracy of the motion capture system.

Practical use degree of Motion Capture technology is low in korea game market which did growth of MMORPG putting first. However, that is dance game or FPS, sports game genre is magnified. Therefore, practical use degree of Motion Capture technology is increasing. And, need various research to take advantage of Motion Capture technology effectively. Studied 3D game character animation manufacture pipe line for it. Characteristic of this manufacture pipe line is work classification, correction of two times, Biped format all-in-one to progress Motion Capture technology and keyframe-animation work at the same time. Also, manufacture pipe line that is consisted of this constituent has economic performance, extensity, systemicity.

Recently, motion capture has become one of the most promising technologies in animation. Realistic motion data can be captured by recording the movement of a real actor with an optical or magnetic motion capture system. This paper deals with motion editing by a geometric mean filter. Since the captured motion has some noises that cause a jerky motion, it needs a smoothing process to make it natural. A geometric mean filter is proposed to produce natural motions without jerky motions. Experimental results show that the geometric mean filter can effectively remove noises that cause a jerky motion and it can guarantee the most natural motions among various spatial filters. This method could be applied to the various fields such as real time animation, virtual reality applications, 3D applications, and etc.

We developed a motion capture system to get angle data of human joints in the walking mode. The motion capture system is a pair of leg-shape device, which is composed of three links with ankle, knee and pelvis joints. The sensors for measurement of the joint angle are potentiometers. We used an A/D converter to get digital data from joint angles, and which are used to simulate and coordinate the biped-walking robot developed in our laboratory. To simulate and analyze walking motion, animation based on three-dimension motion is performed using the open inventor software.
