Abstract:

To solve the difficulties in insulator fault detection during drone-based transmission line inspections, an innovative method for insulator fault detection which combines Real Enhanced Super Resolution Generative Adversarial Network (Real-ESRGAN) and improved YOLOv8n is proposed. Firstly, Real-ESRGAN is adopted to perform super-resolution reconstruction on the dataset, in order to optimize the quality of the dataset and effectively reduce the interference of complex backgrounds. Then, an efficient visual transformer framework is used to replace the backbone of YOLOv8, enhancing the model's feature extraction ability and accelerating the image process at inference stage. Lightweight processing is carried out on detection heads of YOLOv8 to further accelerate the inference of the model. Experimental results show that the mean average precision of this detection method reaches 86.7%, demonstrating its excellent object detection performance in complex backgrounds. Finally, by analyzing heat maps, the differences between the results made by the proposed method and the traditional YOLOv8 in the focus area are displayed, revealing the internal working mechanism of the mode.
