Summary:The present invention relates to a camera rig method for acquiring 3D data, which includes the steps of: (a) aligning a plurality of cameras based on a feature point matching rate for images acquired from a plurality of cameras; (b) acquiring images simultaneously captured by the plurality of cameras according to trigger signals provided to the plurality of cameras at the same time; (c) generating a mesh by calculating a position of each point of a point cloud through parameters for converting the images into the 3D data; and (d) generating 3D modeling data by projecting a material matched with the coordinates of the mesh. Accordingly, the present invention can perform an efficient photographing operation according to the size of a subject. 본 발명은 3차원 데이터를 획득하기 위한 카메라 리그 방법에 관한 것으로서, (a) 복수의 카메라들로부터 획득된 이미지들에 대한 특징점 매칭율을 기초로 상기 복수의 카메라들을 정렬하는 단계; (b) 상기 복수의 카메라들에 동시에 제공된 트리거 신호에 따라 상기 복수의 카메라들에 의하여 동시에 촬영된 이미지들을 획득하는 단계; (c) 상기 이미지들을 3차원 데이터로 변환하기 위한 파라미터들을 통해 포인트 클라우드의 각 점의 위치를 계산하여 메쉬를 생성하는 단계; 및 (d) 상기 메쉬의 좌표와 매칭되는 재질을 투영하여 3차원 모델링 데이터를 생성하는 단계를 포함한다.
