基于改进YOLOv8n的接触网绝缘子检测算法研究
Improved YOLOv8n Algorithm for Contact Network Insulator Detection
摘要
Abstract
In view of the susceptibility of high-speed railway insulator detection to climatic and environmental factors,as well as the deficiencies in accuracy and efficiency,this study proposes an improved algorithm ABFP-YOLOv8.This method first constructs a C2f-AFE module to strengthen the extraction ability of global contextu-al features and suppress complex background interference.Subsequently,the neck network is replaced with a BC-Neck structure to enhance the ability to capture target details.Furthermore,the Powerful-IoU loss function is em-ployed to optimize the localization performance and reduce the false detection rate.Additionally,a 160×160 small target detection head is added to enhance the recognition ability of small-sized insulators.Experimental re-sults indicate that,compared with the original YOLOv8n model,the ABFP-YOLOv8 model achieves improve-ment in mAP@50 and mAP@50-95,increase in inference speed,despite reduction in the number of parameters.This suggests that the algorithm is highly suitable for deployment in mobile detection terminals and scenarios with complex and variable detection environments.关键词
