光载波条纹自动化图像处理

本文提出一种全自动的光载波条纹处理方法，只需要一幅光载波调制的条纹图就能提取出完整的信息。先用ＦＦＴ滤波求出带有光载波的初始位相，接着用反复平均法提高位相信息的质量，然后用是小二乘法构造光载波的位相，两位相相减得出信息的位相。

Automated Image Processing for Analysis of Carrier Cided Fringe Pattern

A novel algorithm of image processing for the analysis of carrier fringe pattern isproposed. Only one fringe Pattern that is carrier ceded is need for extracting unambiguousinformation.The coded fringe pattern is first FFF filtered to get an initial phase with carrierphase in it. Several times of phase shift iteration are carried out to improve the phase.Thenthe carrier is removed by subtracting the pure barrier phase from the cede phase.Thealgorithm offer higher precision over the FFT-transform technique in literature.
