This paper presents a novel method that leverages the stereo geometric relationship between projector and camera for absolute phase unwrapping on a standard one-projector and one-camera structured light system. Specifically, we use only one additional binary random image and the epipolar geometric constraint to generate a coarse correspondence map between projector and camera images. The coarse correspondence map is further refined by using the wrapped phase as a constraint. We then use the… 

Absolute three-dimensional shape measurement combining digital image correlation and phase-shifting methods

Phase-shifting methods have been extensively employed in high-resolution and high-speed absolute three-dimensional (3D) measurements. In the process of 3D reconstruction, one of the important tasks
