Abstract

Recently due to the increasing attention paid to personal education, medical welfare, leisure sports and other leisure activities, various self-coaching systems are being developed for education, rehabilitation exercises and sports for self-learning without external help. In this paper, we explain the human motion capturing system for realization of a self-coaching system, and present the results of the captured human motions using this system. The human body model based motion capture system comprises 15 inertial sensors, a 3-channel receiver, a human body model based 3-dimensional simulation program, and a personal computer. We experiments of subject's motion data obtaining using the commercial motion capture system for verification of construction motion capture system. As a result, the expert and user takes action was appear equally on three-dimensional simulation.

최근에는 의료복지, 레포츠, 기타 여가 생활 등에 대한 관심이 높아짐에 따라 재활운동, 스포츠 등을 별도의 도움 없이 스스로 학습할 수 있는 다양한 셀프-코칭 시스템이 개발되고 있다. 본 논문에서는 셀프-코칭 시스템 구현을 위한 인체모션 캡쳐 시스템에 대하여 설명하고, 구축한 시스템을 이용한 인체모션 취득 결과를 보인다. 구축된 시스템은 인체모션 취득을 위한 MEMS 기반 관성센서 15개와 3채널의 수신기, 실시간 모션캡쳐 및 시뮬레이션이 가능한 인체모델 기반 3차원 시뮬레이션 프로그램과 PC, 그리고 데이터베이스 구축을 위한 서버로 구성된다. 구축한 시스템의 검증을 위해 상용 모션캡쳐 시스템을 이용하여 대상자의 모션 데이터를 취득하는 실험을 진행하였다. 실험결과, 전문가와 사용자가 취하는 실제 동작이 구축한 인체모션 캡쳐 시스템에 동일하게 나타나는 것을 확인하였다.
