Power transmission line inspection image preprocessing method

The invention discloses a power transmission line inspection image preprocessing method, and aims to solve the problem of low inspection image utilization rate caused by the fact that the unmanned aerial vehicle power transmission line inspection image in the prior art has a large amount of distortion, blurring or lens pollution and the like and cannot meet the requirements of identification and detection work. Comprising the following steps: acquiring inspection images, performing quality judgment on the inspection images based on image multi-feature information including image quality features, image content features and image space features, dividing the inspection images meeting the detection image quality into to-be-detected images, and dividing the inspection images not meeting the detection image quality into to-be-processed images; and judging the to-be-processed image, processing the to-be-processed image according to a preset processing method corresponding to a judgment result, and performing image
