摘　　要：本文介绍了投影栅线相位法测量三维相貌的的基本原理,讨论了栅线周期数对三维形貌测量结果的影响。通过对石膏人脸像的测量结果发现,并不是栅线周期数越大,测量结果越精确。为了保证测量质量,同时提高效率,对于石膏人脸像,选择周期为20像素进行测量比较合适。The projected grating phase method to measure the 3-D appearance of basic principle is introduced in this paper.The influence of 3-D shape measurement result with grating cycles is discussed.The measurement result of the plaster face shows that it is not the grating cycles increasing,the measurement results is more accurate.In order to guarantee the quality,while improving the efficiency,as the plaster face,the cycle of 20 pixel is the best choice.
