The noise in the Gas Insulation Station (GIS) equipment fault picture obtained for the X-ray imaging system cannot be eliminated due to the use of common filters, and the noise will affect the subsequent edge feature extraction. Therefore, MCPDE (Coupling Partial Differential Equation Model of Nonlinear Diffusion) is selected for noise suppression. This model greatly considers the image fidelity after denoising and has good stability. For the denoised image, taking into account the accuracy of the edge contour, the unsupervised nonlinear algorithm based on the McLaughlin function curve fitting is used for contour extraction. The experimental results show that the method is effective.
