초록

본 논문에서는 증강현실 환경에서 등장하는 3차원 공간상의 객체를 카메라와 손을 사용하여 조작할 수 있는 인터페이스를 제안한다. 일반적으로 3차원 움직임을 검출하기 위해서 마커를 사용하지만, 이러한 경우에는 객체를 등록하기 위해서 마커가 영상 내에 있어야 하며 추가적인 장비를 사용함으로서 몰입감의 저하를 초래한다. 이것을 극복하기 위해서 본 연구에서는 손을 하나의 평면으로 변환하고 손 모양의 변화를 검출하여 마커를 대체하는 방법을 제안한다. 또한 조명으로 인한 손의 색상 변화에 따른 객체의 등록 위치 변화를 칼만 필터를 적용하여 추적하였다. 실험결과, 제안한 알고리즘은 손의 원활한 움직임에 의한 객체의 3차원 조작이 가능함을 보였다.

In this paper, we propose a hand gesture interface for the manipulation of augmented objects in 3D space using a camera. Generally a marker is used for the detection of 3D movement in 2D images. However marker based system has obvious defects since markers are always to be included in the image or we need additional equipments for controling objects, which results in reduced immersion. To overcome this problem, we replace marker by planar hand shape by estimating the hand pose. Kalman filter is for robust tracking of the hand shape. The experimental result indicates the feasibility of the proposed algorithm for hand based AR interfaces.
