Insulator defect detection method based on complex environment background condition

The invention provides an insulator defect detection method based on a complex environment background condition. The method comprises the following steps: carrying out data enhancement on insulator defect image data acquired by an unmanned aerial vehicle; after data enhancement, preprocessing image data, normalizing the image data, and scaling the image into the size of 640 * 640 * 3; and after preprocessing, inputting the image into a preset network model to obtain a detection result. According to the insulator defect detection method, the problem that insulator defect detection is not accurate under the complex environment background condition can be solved, the function of accurately detecting the insulator defects under various complex conditions is achieved, the detection result of the insulator defects in the power transmission line is optimized, and the accuracy of insulator defect detection in the complex environment background is improved. According to the invention, the position of the insulator def
