这是在MATLAB下编写的基于彩色条纹的相位测量轮廓术的源码,很实用.,在光学三维测量中

function [R2G,R2B,G2R,G2B,B2R,B2G] = CalculateCouplingEffects(RFringe1,RFringe2,RFringe3,GFringe1,GFringe2,GFringe3,BFringe1,BFringe2,BFringe3)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%此函数用来计算彩色条纹在各个通道上的影响。输入九个条纹，红，绿，蓝个三个，其中
%每种颜色相互间差2*pi/3，输出为相互影响的系数,其中R2G表示在红通道上绿通道对它的
%影响，其余类推。。。
