摘　　要：本文探讨了CT图像边缘提取的常规方法,引入了启发式搜索算法用于工业CT图像的边缘信息提取;通过这种方法可以得到连接闭合的单象素边缘图像,为将来的序列CT图像三维重建提供了原始数据。最后针对箱包CT图像进行了算法验证,实验表明在图像存在噪声和伪影的情况下,算法仍能检测出满足三维重建需求的边缘信息。Conventional algorithm of edge extraction in industrial CT images is studied in the paper.Heuristic search is used to link up the edge point and identify the precise and closed edge lines which provide original data for 3-D reconstruction of serial CT images.The experiments show that even in the noise and artifact images,the designed algorithm performs well and meet the expected need.
