Abstract	Phase shifting is a widely used method for accurate and dense 3D reconstruction. However, at least three images of the same scene are required for each reconstruction, so measurement errors are inevitable in dynamic scenes, even with high-speed hardware. In this paper, we propose a Fourier transform assisted phase shifting method to overcome the motion vulnerability in phase shifting. A new model with motion-related phase shifts is formulated, and the coarse phase measurements obtained by Fourier transform profilemetry are used to estimate the unknown phase shifts. The phase errors caused by motion are greatly reduced in this way. Experimental results show that the proposed method can obtain accurate and dense 3D reconstruction of dynamic scenes, with regard to different kinds of motion.
