Title: 높이 및 깊이 정보를 포함하는 이차원 평면상의 면적을 삼차원 구 표면에 투사하는 기법을 이용하여 동작 가능 영역을 설정한 3 자유도 이하 회전형 관절 설계 기법
IPC: A61F5/00
Filed: 1998-09-04
Abstract: 본 발명은 동작 영역 제약을 가진 관절 표현 기법에 관한 것이다. 먼저 삼차원 관절의 생성에 관하여 고려하자. 3자유도 회전형 관절의 동작은 구의 구조를 통하여 설명할 수 있는데, 구를 하나의 완전한 3 자유도를 갖는 물체로 간주할 수 있고, 이러한 3 자유도 물체를 다음과 같이 구성할 수 있다. 구의 중심에 막대가 연결되어 있으며, 이 막대는 구의 중심이 시작이고 구의 표면이 끝인 벡터로서, 이 벡터는 구의 표면의 접면에 수직이다. 이 경우, 구 표면상에서의 막대기 끝의 움직임은 2 자유도를 가지며, 만약  이 벡터가 자기자신이 나아가는 방향을 기준으로 회전할 수 있으면 자유도가 하나 더 추가되어 완전한 3 자유도 관절을 이루게 된다.(제 1도 참조) 
     본 발명은 관절에 있어서 동작 영역 제약을 가진 관절을 설계하는 기법에 관한 것이다. 2 자유도 관절에 대한 동작 영역에 있어서 보다 쉽게 제약을 설정하기 위하여, 2 차원 평면상에 폐곡선 혹은 다각형으로 표현되는 영역을 설정하고 이 영역을 동작 가능한 영역으로 간주할 수 있으며,(제 2도 참고) 이 2 차원 평면상의 영역을 삼차원 공간상의 구의 표면에 투사(projection)하면 구 표면에 영역을 설정할 수 있다. 이렇게 하여 우리가 원하는 부위가 동작 가능한 영역으로 설정되었는지를 확인하여 원래의 2 차원 평면상의 영역을 수정하면 된다. 관절의 움직임은 구의 표면에 설정된 영역 내에서만 움직이도록 제약을 받게한다. 이 기법을 적용하는데 있어서 3 자유도 관절 뿐만 아니라 1 자유도 혹은 2 자유도 관절에 대하여도 적용할 수 있다. 
     3 자유도 관절의 경우, 벡터가 나아가는 방향으로 회전할 수 있는데, 이 회전 범위에 대하여 제약을 가할 수 있어야 한다. 제약을 가하기 위하여 2 차원 평면상에 설정한 영역에 깊이 및 높이 정보를 추가하는데,(제 3 도 참고) 평면을 기준으로  높이 정보는 양의 방향으로 벡터를 최대한 회전 가능한 각도를 지정하고, 깊이 정보는 음의  방향으로 벡터를 최대한 회전 가능한 각도를 지정한다. 물론 구의 표면상의 동작 가능 영역을 지정하는  2 자유도 이하의 관절을 설계할 경우, 이 정보는 투사되지 않는다. 즉 높이와 깊이 정보를 포함하는 2 차원 평면을 구의 표면에 투사 시키는데 있어서, 설계하는 회전형 관절이 2 자유도 이하일 경우, 높이와 깊이 정보는 의미가 없으며, 단순히 0으로 표현된다.
