본 논문에서는 2 대의 카메라로부터 입력된 스테레오 영상을 이용하여 가상캐릭터의 동작을 실시간으로 생성하는 방법에 대해 기술한다. 이 시스템은 동작자의 움직임을 캡쳐하기 위해 동작자의 좌, 우 전방에 동기화된 2 대의 컬러 CCD 카메라를 위치시킨다. 카메라로부터 입력된 스테레오 영상을 분석하여 신체의 중심이 되는 루트와 머리, 손, 발과 같은 end-effector의 2차원 특징점을 추출하고, 추출된 특징점들은 카메라의 사영행렬과 추적 알고리즘을 통해 3차원 위치를 생성한다. 생성된 루트와 end-effector 의 3 차원 위치정보는 노이즈 제거를 위한 필터링을 거친 후 역운동학 알고리듬에 적용하고, 인체 관절의 해부학적인 제약조건과 관절간의 상호 연관성 및 전 후 프레임간의 부드러운 연결 동작 생성을 고려하여 중간관절의 위치를 정밀하게 계산한다. 중간관절의 위치를 생성하므로 서 임의 동작자의 움직임에 대한 모든 관절의 정보를 획득할 수 있으며, 획득된 동작 데이터를 가상 캐릭터에 적용하므로 서 캐릭터의 움직임을 실시간으로 생성할 수 있다.
