| Abstract: | Based on computer image procession and contour analysis as well as through the actual cases, it is shown that the method proposed reduces the bad influences taken by the background noise and edge illegibility in the infrared thermal image, and the recognition of the outline of the object inspected and the overheated region having high accuracy. The work is of engineering applicaion value to carry out infrared non-destructive inspection, improve diagnosis efficiency and avoid mistakes. |
