摘要：

概述了基于相位测量的光学三维面型测量原理和移相法相位测量技术。针对移相法相位测量过程中的移相误差,结合优化的方法研究了传统五步移相算法的误差估计。根据相位展开原理,提出了加权最小二乘相位展开方法,并分别用两种不同的优化方法进行二维相位展开,对结果比较分析,验证了其性能与效率。

Abstract:

The relative principle of optical threedimensional measurement based on phaseshift technique is introduced. Combining with the optimization method for the first time, error estimation of the traditional fivesample phase shifting algorithm is studied. According to the phase unwrapping principle, a weighted least square phase unwrapping algorithm is proposed. For the object problem, the Matlab program of two different optimization methods is designed on the 2D phase unwrapping. Comparing and analyzing its result, the function and efficiency are verified.

Key words: shift phase; phase unwrapping; leastsquare method; genetic algorithm
