This Letter presents a multiview phase shifting (MPS) framework for full-resolution and high-speed reconstruction of arbitrary shape dynamic objects. Unlike conventional methods, this framework can directly find the corresponding points from the wrapped phase-maps. Therefore, only a minimum number of images are required for phase shifting to measure arbitrary shape objects, including discontinuous surfaces. Benefit from phase shifting MPS can achieve full spatial resolution and high, accurate 3D reconstruction. Benefit from multiview constraint MPS is also robust to discontinuities. Experimental results are presented to verify the performance of the proposed technique.
