Abstract
We have developed a video-rate stereo machine which has the capability of generating a dense range map at video rate. The CMU video-rate stereo machine has the following performance: 1) multi image input of up to 6 cameras; 2) throughput of 30 million point × disparity measurements per second; 3) frame rate of 30 frames/sec; 4) a dense depth map of 256 × 240 pixels; 5) disparity search range of up to 60 pixels; and 6) high precision of up to 8 bits (with interpolation). The capability of producing such a high resolution depth map (3D representation) at video rate opens up a new class of applications for 3D vision. We report one such application: z keying, which merges the real and virtual worlds in real time.
