The invention discloses a method for diagnosing a surface crack fault of a blade of a wind turbine generator of an electric power system based on a machine vision image. The method comprises the first step of dividing the blade of the wind turbine generator to obtain blade elements, the second step of photographing the blade elements of the wind turbine generator and removing a background, the third step of carrying out secondary division on a blade element result image obtained in the second step to obtain image elements and carrying out feature extraction on the element result image, the fourth step of training a support vector machine used for diagnosing the fault, the fifth step of diagnosing the surface fault mode of the blade elements of the wind turbine generator through the trained support vector machine, and the sixth step of carrying out the operations of the second step, the third step and the fifth step on all the blade elements until the surface fault diagnosis of the whole blade is completed. The method is high in diagnosis precision.
