摘　　要：提出一种周期组合颜色编解码方法.采用红、绿、蓝三种基本色形成彩色条纹,将任意相邻三条彩色条纹作为一组,其排列顺序是唯一的,再利用白色条纹来标记周期编号,该编码方法用较少的颜色数实现了较大的编码空间,增加了抗干扰性,且解码较容易.为精确解码,本文对彩色条纹分割进行了研究,提出基于改进Canny边缘检测算子的自适应彩色条纹分割算法.在此基础之上,对彩色条纹进行解码,主要包括:1基于白色条纹逐级解码算法;2遗漏彩色条纹解码算法.实验结果表明,该方法既具有较大的编码周期,又容易提取条纹,保证了条纹解码的准确度,达到了较好的结果.A periodic permutation color structured light coding and decoding method is presented. The method use red, green and blue three primary colors as the encoding stripe pattern,and make any adjacent three color stripes as a group. So the stripe＇s order is u- nique. Then use white stripes to mark the periodic color stripe patterns to distinguish different coding groups. This method can achieve a larger coding space with less colors, increase the noise immunity and make the decoding easier. In order to accurately decode, an a- daptive color stripes segmentation method based on improved Canny edge-detection operator is presented. It includes two aspects： （ 1 ） sequentially decoding the color stripes based on the white stripes; （ 2 ） omitted color stripes decoding. Experimental results show that the method has a large coding periodic space, and can extract stripes easily. It can also ensure the accuracy of the stripes decoding, and achieve a good coding and decoding result.
