| 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 ... |
