A DeBruijn Color Structured Light Decoding Algorithm Based on Color Transfer Technique
High-precision decoding is a key problem of DeBruijn color structured light three-dimensional measurement. We proposed a DeBruijn color structured light decoding algorithm based on color transfer technology. Firstly, the color information of the structured light-coded image is used as priori knowledge, and the color structured light projection image is enhanced and de-illuminated by the color transfer method to restore its stripe color information. Secondly, the central coordinates of fringe are extracted accurately based on the proposed dual-step sub-pixel extraction algorithm for stripe center point positioning of color structured light projection image . Finally, the matching of feature points is performed based on the dynamic programming algorithm. The experimental results show that the proposed algorithm can effectively improve the decoding accuracy, and has strong robustness under the condition that the texture of the illumination and the surface texture of the measured object lead to the degradation of the structure light projection image quality.
