In this paper, we describe high-speed 3D position and normal measurement of a specified point of interest using a high-speed projector-camera systems. A special cross line pattern is adaptively projected onto the point of interest and the reflected pattern on an object surface is captured by the camera and analyzed to obtain the position and normal information. The experimental results show that the estimated normal directions were apparently correct and stable except for occasional large errors due to instantaneous detection failures. Based on this measurement system, we describe a game system by which real-time interaction with non-structured 3D real environment is achieved.
