In one embodiment of the present invention, sample collection is to enable the YOLO algorithm to accurately identify hidden trouble near the power line, and a large number of related image samples, such as an excavator, an excessively high tree, etc., are first required. In the aspect of the type selection of the acquisition equipment, based on the consideration of image quality, flight stability and endurance, the flight path of the unmanned aerial vehicle is planned according to the power line layout, and the image acquisition is carried out by adopting unmanned aerial vehicle equipment such as M3E or M30T matched with a large airport. And image capturing is performed on the power line and the surrounding environment thereof under different time, place, weather and season conditions to capture potential hidden trouble.
In one embodiment of the invention, the data preprocessing is to perform data cleaning on massive image data acquired by the unmanned aerial vehicle, and screen out high-quality representative images. As shown in fig. 2, a labeling tool (e.g., labelImg, etc.) is used to locate the target (e.g., excavator) in each sample image and give the corresponding label.
