英文摘要	In this paper a 3D shape measurement system based on the grating method was developed. The system consists of two CCD cameras and a DLP projector. The multi-frequency heterodyne principle was presented to overcome the unwrapping problem of phase functions, and a phase-to-coordinates conversion algorithm was proposed to reconstruct the 3D geometry from the unwrapped phase map. To demonstrate the performance of this 3D measurement system, a face model was measured, and the reconstructed 3D geometric surface is very smooth with details. Additionally, a ladder with one step was measured. The result shows the system can measure the discontinuous object and get high measurement precision.
