title: A correspondence finding method based on space conversion in 3D shape measurement using fringe projection.
abstract: Phase correlation is an effective method used for 3D shape measurement. It has a defect in the step of finding corresponding points. This work analyses the complexity of phase maps and the problems caused by it in real applications, proposes a correspondence finding method based on space conversion. Applying space conversion, two sets of phase maps from two cameras are integrated to a unique phase space. Accordingly, searching corresponding point between two images can be carried out in the same image coordinate system of the projector. As a supplementary, two algorithms are given for CC method and VR method. Experimental results show that proposed algorithms are successful and effective.
