【Abstract】 Icing problems in winter transmission lines often have serious consequences for power supply safety. Accurate ice edge detection is a key issue in ice thickness calculation. The improved Canny operator’s excellent edge detection performance is used for ice edge detection. It is proposed to use the morphological filtering based denoising method instead of the traditional Gaussian filtering, combined with the influence of the diagonal direction elements, to detect the edges with the improved Canny operator,and provide reliable technical support for calculating the ice thickness. The research shows that this method can accurately detect the edge of ice coating compared with the traditional edge detection algorithm, which is of great significance for ice thickness calculation and deicing technology.更多还原
