A phase correction method that utilizes fringe color-coding in phase-measuring profilometry is proposed. Original and additional fringes are encoded into the R and B channels, respectively. The R + B channel patterns are projected onto an object, captured using a camera, where the R and B channels are extracted. Then, phase shifts obtained from the R and B channels are utilized for absolute phase calculation and correction. Simulations and experiments demonstrate that this method can correct edge order errors and avoid increasing the fringe number. Experiments performed using the R + G, G + B, and R + B channels demonstrate that R + B exhibits the least color crosstalk.

基于颜色编码条纹的相位测量轮廓图的绝对相位校正

提出了一种在相位测量轮廓测量中利用条纹颜色编码的相位校正方法。原始和附加条纹分别被编码到R和B通道中。将R + B通道模式投影到使用相机捕获的对象上，然后提取R和B通道。然后，将从R和B通道获得的相移用于绝对相位计算和校正。仿真和实验表明，该方法可以校正边缘顺序误差，并避免增加条纹数。使用R + G，G + B和R + B通道进行的实验表明，R + B表现出最少的颜色串扰。
