基于工业CT的工件缺陷识别方法

工业CT是一种有效的工件缺陷识别的方法,代表着无损检测技术的发展方向.首先概述工业CT技术在工件缺陷识别中的应用,并把其他和其他常用方法进行了简单比较;接着从工件缺陷识别的流程入手,对每个步骤都从处理思路和处理方法方面作了阐述;然后对一些在工件缺陷识别方面很有潜力的算法(Level set和Gabor小波)进行了介绍和分析;最后对工业CT在工件缺陷识别方面的应用前景进行了展望.

Workpiece defect recognition methods based on industrial CT

Industrial CT is an effective method of workpiece defect recognition, which represents the development orientation of nondestructive test. This paper first summarizes the application of Industrial CT to workpiece defect recognition, and makes a brief comparison with other common ways. Then, each step of recognition process is explained form the aspects of the idea and the methods. In the following part, some methods which have potentials in workpiece defect recognition (Level Set method and Gabor analysis) were introduced and analyzed. Finally, the prospect of industrial CT application to workpiece defect recognition is discussed.
