Abstract :
The switching arc image of low voltage apparatus has been captured with a high frame rate CCD camera system and composed filter technology. In this paper, the discussion is focused on the theory of edge detection. An efficient image edge detection operator, Canny operator, is introduced to the processing of arc image. The performance of Canny operator and the traditional operators in the practical edge detection of arc image is analyzed. Experimental results prove that Canny operator is better than Roberts, Sobel, Prewitt, Log operators by analyzing weak edge region in the switching arc image. And Canny operator is suitable for the edge detection of arc image of low voltage apparatus.
