The binary defocusing technique is widely used for high-speed three-dimension (3D) reconstruction. However, the system distortion directly influences the reconstruction quality, and most of the previous works are only for the traditional digital fringe projection (DFP) technique. Based on the problems above, this paper first analyzes the distortion for the input-output response of the system and the influence of space luminance distribution uniformity of the projector, in the binary defocusing technique. Then, a novel method combining initial correction and iterative correction is proposed to obtain accurate sinusoidal fringe patterns. Finally, the experimental results show that the proposed method can correct sinusoidal fringe phase error in binary defocusing technique significantly and improve the quality of 3D reconstruction effectively.
