Abstract
In order to identify projection light color information of the color structured light system rapidly and accurately,aprojection light color correction algorithm based on color reflection model is proposed in this paper.Firstly,the two coupling difference is eliminated by chromaticity calibration of projector and camera.Then,the effect on projection light color caused by the color of the object surface and height light is revised by estimating three-channel spectral reflectance of the object while separating specular component and diffuse component.The experiment result shows that the proposed projection light color correction algorithm for color recognition of color structured light with color reflection model has some advantages,such as high robustness,fast calculation and high recognition accuracy.
