Abstract

This paper describes a range imaging system being developed based on a high-speed space encoding projector. Space encoding allows the identity of 2 to the B projected light stripes to be unambiguously determined by the projection of B + 2 coding patterns. Range to each projected stripe element can then be determined by triangulation and a range image of the illuminated scene generated. The projector makes it possible for the coding patterns to be projected at camera frame rates. The complete system, consisting of the projector, a 60 Hz frame rate charge-coupled device (CCD) camera, and processing electronics, will be able to acquire an 8 bit, 256 by 256 pixel range image in 1/6 second.
