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

Abstract

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.
