A new flexible acquisition system of ray-space data for arbitrary objects

Conventional ray-space acquisition systems require very precise mechanisms to control the small movement of cameras or objects. Most of them adopt camera with a gantry or a turntable. Although they are good for acquiring the ray-space of small objects, they are not suitable for ray-space acquisition of very large structures, such as a building, tower, etc. This paper proposes a new ray-space acquisition system which consists of a camera and a 3-D position and orientation sensor. It is not only a compact and easy-to-handle system, but is also free from limitations of size or shape, in principle. It can obtain any ray-space data as far as the camera is located within the coverage of the 3-D sensor. This paper describes our system and its specifications. Experimental results are also presented
