High-precision detection fault diagnosis method and system for overheating defect of power line clamp

The invention discloses a high-precision detection fault diagnosis method and system for an overheating defect of a power line clamp. The method comprises the following steps: shooting an infrared image of a wire clamp wire in a power system through an infrared thermal imager; carrying out frame selection on equipment to be diagnosed by utilizing a lightweight rotation detection algorithm; and according to the coordinates of the infrared image detection frame and the temperature dictionary, obtaining the hot spot temperature of the wire clamp and the wire target area, and carrying out wire clamp fault diagnosis. Real-time target detection of a wire clamp wire is realized, and a continuous improvement mechanism of the performance of a rotary detection model is realized, so that the detection precision of the system is maintained at a high level, and then diagnosis and classification of wire clamp faults are completed. 本发明公开了电力线夹过热缺陷的高精度检测故障诊断方法及系统，包括：通过红外热成像仪拍摄电力系统中线夹导线的红外图像；利用轻量化旋转检测算法，对待诊断的设备进行框选；根据红外图像检测框坐标
