S Zhang and S-T Yau, "Simultaneous three-dimensional geometry and color texture acquisition using a single-chip color camera," Opt. Eng. 47(12), 123604, 2008; doi: 10.1117/1.3046715
A novel technique that uses a single color camera to capture high-resolution three-dimensional 3-D geometry and the perfectly aligned color texture simultaneously is discussed. A projector projects three phase-shifted black-and-white fringe patterns onto the object, and a color camera captures the fringe images reflected by the object. From these three fringe images, both 3-D shape and the color texture are obtained. Moreover, since only three fringe images are required, this proposed technique permits real-time 3-D shape measurement. Experiments are presented to demonstrate the success of this technique.
