Paper Abstract

A new geometrical model and mathematical method for three-dimensional surface reconstruction with phase- shifting structured light technique is proposed. First, with the proposed method, there will be no restriction to camera and projector's relative alignment on parallelism and perpendicularity. Furthermore, the depth map can be directly derived from the phase map by a simple function. The x and y coordinates are inferred from the depth z coordinate. Second, no special calibration hardware is needed; a simple two-step plane-based calibration procedure is adopted to acquire the system intrinsic and extrinsic parameters. Third, a look-up-table compensation method is presented to avoid the accumulation of errors introduced in the structured light system. The experimental results demonstrate the e®ectiveness and accuracy of the proposed methods.
