Abstract

In this paper, we propose a novel 3-D measurement system, which consists of 1) spatially phase-modulated light for encoding the projection angle, and 2) the three-phase correlation image sensor (3PCIS) for decoding amplitude and phase of time-varying intensity of light. The projection angle map is obtained based on spatio-temporal phase unwrapping method we propose. We implemented this system using our CMOS 00 times 200$ -pixel 3PCIS, and successfully reconstructed the range map in real time.
