The invention discloses a texture based method for extracting characteristics of transmission line equipment. The method comprises the following steps: (1) acquiring image information of the transmission line equipment, equally dividing the image by an image acquiring function, and obtaining the information of the evenly-divided images one by one; (2) according to the image information, by using a gray co-occurrence matrix function, computing a gray co-occurrence matrix corresponding to the image and used as an input of a texture computing function; (3) according to the gray co-occurrence matrix and the gray information of the original image, computing texture characteristic values by the texture computing function, and according to eight formulas of computing the texture characteristic quantities, obtaining the characteristic values of the texture characteristic quantities; and (4) forming a characteristic quantity sequence by the characteristic quantities of the equal divided images, traversing the sequence to search a mutation point of the characteristic quantity, determining the position where the mutation of the characteristic quantity happens, and determining the evenly divided image corresponding to the characteristic quantity to be a failure point of the transmission line equipment. The method has advantages of conveniently determining and differentiating the conditions of the transmission line equipment, having high maintenance efficiency, and ensuring the safety and the stability of the transmission line.
