摘　　要：针对压力容器无损检测中胶片焊缝的缺陷识别,根据缺陷图像的特征,采用图像预处理、图像分割算法,专家系统等方法,提出了一种胶片焊缝缺陷的识别方法,并在MATLAB下实现。介绍了专家系统的基本原理、结构、建立方法和识别策略,根据焊缝缺陷特征,从不同层次进行识别。通过不断的试验来完善胶片缺陷专家系统库,进一步提高缺陷识别率。According to the characteristics of image defects, this paper integrated use of image preprocessing, image segmentation algorithms, expert systems and other methods, presented a film weld defect identification method for nondestructive testing in the pressure vessel weld defect recognition, and to achieve in MATLAB. This paper also described the expert system＇s basic principles, structure, establish methods and identification strategy. In the light of the weld defect characteristics from different levels of recognition, through continuous testing to improve the film defect system library and to further enhance the defect recognition rate.
