摘要

摘要: 针对条纹投影术提取物体高度信息的问题，提出了一种新的基于彩色光栅投影的三维测量方法。对选取G分量为255，R，B分量各取0或255而组成的青、白、黄、绿四色遵循格雷码原理进行编码，然后将G分量作正弦调制形成投影光栅投向被测物体。提取采集到的光栅变形图中G分量，利用傅里叶变换方法得到其初始相位；同时对采集到图像中的R，B分量作阈值迭代分割而G分量自动赋值为255,综合三分量信息得到条纹颜色信息进而获取条纹的周期信息，从而展开相位。全过程仅需投影一幅彩色光栅图就能完成三维测量，实验结果表明该算法易于实现，在测量实时性和精确性上表现良好。

Abstract: A rapid 3D measurement technique based on color coding fringe projection is proposed. The 3D shape information of an object can be obtained by only one color-encoded fringe pattern image. The color-encoded stripes were embedded into a sinusoidal fringe pattern in order to get the absolute shape of an object. Phase unwrapping was performed according to the color-encoded stripes. A novel color coding method using four colors was designed. The sinusoidal G component of a color image was used to obtain the phase by Fourier transform method, the R and B components were used to identify the fringe order so that phase unwrapping can be easily done. Only one frame of color image is needed to get the 3D information of an object, experiments indicate that the 3D information of an object can be obtained accurately and rapidly.
