摘要

采用彩色编码结构光对彩色目标进行三维测量，由于两种颜色的叠加，彩色条纹在目标上的颜色会发生畸变变化，造成彩色条纹的解码误差，导致测量误差。针对这一问题，提出了一种颜色分量信息处理方法，通过回归分析建立了反射光、入射光与表面颜色关系的数学模型，采用最小二乘法对模型进行求解，从而得到反射光、入射光颜色分量和表面颜色分量的关系。并对投影条纹的颜色进行还原，保证条纹解码的正确性。实验结果表明，该方法具有良好的译码效果。

Research on color components correction and decoding of color-coded structured light in 3D measurement

Adopting color-coded structured light Three-dimensional measurement of color target, due to the superposition of two colors, colored stripes on the target color will occur distorted changes, resulting in decoding errors of colored stripes, leading to measurement error. Focus on this problem, we propose a color component information processing method which through regression analysis build a mathematical model based on the relationship of the reflected light and incident light and the surface color, using the least squares method for solving the model, in order to get the relationship of the reflected light and the incident light color component and surface color component, and restore the color of the projected stripes to ensure the correctness of the striped decode. The experimental results show that this method has a good effect on decoding.
