Abstract

We have developed a video-rate stereo machine that has the capability of generating a dense depth map at the video rate. The performance bench marks of the CMU video-rate stereo machine are: 1) multi image input of up to 6 cameras; 2) throughput of 30 million point-disparity measurements per second; 3) frame rate of 30 frame/sec; 4) a dense depth map of up to 256 x 240 pixels; 5) disparity search range of up to 60 pixels; 6) high precision of depth output up to 8 bi ts (with interpolation). The capability of passively producing such a dense depth map (3D representation) of a scene at the video rate can open up a new class of applications of 3D vision:merging real and virtual worlds in real time.
