Simultaneous three-dimensional geometry and color texture acquisition using a single color camera

Abstract

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 phaseshifted 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.

High-speed measurement of foot shape based on multiple-laser-plane triangulation

“…The simultaneous 3-D and color texture acquisition at high speed by combining color-coded and phase-shifting techniques is described in Ref. 7. The second approach, which is especially fit for dynamic measurement, uses a single image to recover the shape information.…”
