3,000-fps 3-D shape measurement using a high-speed camera-projector system

This paper proposes a high frame rate 3-D shape measurement system based on structured light projection using temporally-coded binary patterns. This system consists of a DMD (digital micromirror device) projector and a high-speed camera, both of which operate at over 6,000 fps. Introducing an image processing algorithm of detecting and tracking the projected light patterns enables frame-by-frame 3-D image measurement. Experimental results show that the proposed algorithms worked effectively, and the system achieved 3-D imaging at 3,350 fps.
