Detection of Longitudinal Belt Rip Based on Canny Operator

The longitudinal rip of belt conveyor often causes coal mine in a stoppage of production, and the fault diagnosis technology of visual processing is adopted. Because of a large amount of dust, most visual processing algorithms are often out of work. In this paper, the edge detection algorithms including Canny operator, Sobel operator and laplacian operator are compared, meanwhile, the python language is applied in image processing, the Canny operator of python programming is simulated and verified. Finally, the canny operator is proved to have good detection effect.
