Color-fringe pattern profilometry is widely developed for high-speed 3D shape measurement due to more information can be extracted through a single color pattern. However, previous researches show that the color coupling and imbalance of the system cause significant errors, which severely influence the accuracy of the color-fringe pattern profilometry. We proposed a point-to-point method to compensate the errors caused by color coupling and imbalance. Different from previous methods, the proposed method bases on the correspondence between camera pixels and projector pixels, which achieves point-to-point compensation of the full field. Experimental results verify that the proposed easy-to-operated method reduces the measurement errors significantly.

彩色条纹图案轮廓测量中颜色耦合和不平衡的点对点补偿方法

彩色条纹图案轮廓测量法是为高速3D形状测量而广泛开发的，因为可以通过单个彩色图案提取更多信息。但是，先前的研究表明，系统的色彩耦合和不平衡会导致严重的误差，严重影响彩色条纹图案轮廓测量的准确性。我们提出了一种点对点的方法来补偿由颜色耦合和不平衡引起的误差。与以前的方法不同，该方法基于相机像素和投影仪像素之间的对应关系，从而实现了全场的点对点补偿。实验结果证明，该方法易于操作，可显着降低测量误差。
