Research on Identification of Color Structured Light Based on Dichromatic Reflection Model

Abstract

In order to identify projection light color information of the color structured light rapidly and accurately, this paper proposes a projection light color correction algorithm based on “Dichromatic Reflection Model”(DRM). This algorithm revises the effect on projection light color which caused by object surface’s color and highlight, through estimating three-channel spectral reflectance of the object, separating specular and diffuse components. The experiment shows that the proposed method has more advantages than the color recognition of color structured light which based on DRM, such as high robustness, fast calculation and high accuracy.
