摘　　要：提出一种新的基于彩色光栅投影的三维面形测量方法.将相移量为2π/3的RGB调制的正弦光栅复合成彩色光栅投影到被测物体表面,利用相移算法求解出相位,最终获得物体的三维数据.该方法只需一幅投影条纹图就可以完成三维测量,同时给出了理论分析和计算机模拟.We proposed a 3D shape measurement technique based on color-encoded fringe projection. A col- or-encoded grating was obtained by synthesizing three grating in order to get the absolute shape of an object. We can get the 3D shape of an object by only one frame of color image. Theory and computer simulations are presented.
