摘　　要：介绍了采用De Bruijn序列对结构光进行编码,基于全局优化思想对条纹边界进行最优邻域匹配,利用增加约束的动态编程遍历最优匹配路径网格得到最优匹配路径;对畸变条纹图像进行颜色校正,提高了边界检测的准确率。该编码策略解码简单,匹配算法能取得较好效果,得到的点云数据精度能够达到三维表面重建的要求。This paper introduced the De Bruijn sequence to encode the structured light,solved the correspondence with the BN-Matching algorithm based on the global optimal,and obtained the best match path by searching the BMP grid with dynamic programming under extra restriction.The color calibration during pretreatment improved the borderline-detected accuracy.This coded strategy is easy to decode,and the BN-Matching can obtain preferable effect.The point-cloud data is fine to reconstruct the 3D surface.
