The invention provides a power transmission line tower body defect detection method and system, and the method comprises the steps: obtaining a field picture of a power transmission tower body, and carrying out the preprocessing of the field picture; inputting the preprocessed picture into a trained detection model, wherein HRNet is used as a feature extraction network of a training model in the detection model; and setting a confidence rate threshold, and limiting an output result of the detection model to obtain a detection result of the transmission tower body. According to the method, aiming at the defects of different sizes in the obtained image, an intelligent detection model for the defects of the power transmission body is built based on HRNet and LibraRCNN algorithms. And inputting the obtained image into the power transmission body defect detection model for analysis, and obtaining the power transmission tower with the defect through an analysis result, thereby realizing intelligent inspection of the power transmission body. And the tower with defects is fed back to operation and maintenance personnel in time, so that hidden accidents can be effectively reduced, and the operation and maintenance efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of transmission line inspection, in particular to a method and system for detecting defects of a transmission line tower body. Background technique [0002] As one of the important infrastructures in our country, the normal operation of transmission lines ensures the normal power supply in various regions. As the support of transmission lines, transmission towers are very important for their own stability and safety. [0003] The detection of existing transmission line towers adopts the method of manual inspection, which is very time-consuming and labor-intensive, and it is difficult to find defects in transmission towers. With the development of drones in recent years, there have been mature cases of using drones for power inspections. UAVs have the advantages of high flexibility, fast emergency response speed, and low cost, and can cover the inspection area in all directions and from multiple angles. Dur...
