Abstract
In real-time phase measurement profilometry (PMP) systems, finding point correspondence between phase-maps of cameras or camera and projector is the key technology for 3D reconstruction. A novel method based on trifocal tensor constrain, which can be directly implemented on wrapped phase-map and speed up by parallel computing technology, is present. But fringe number, images noise and system non-linear response will lead to false correspondence. The influence of these factors is deeply analyzed, and a feasible way is proposed to reject error candidate points. Finally, this method indicated a satisfactory performance in the experiment.
