Abstract Combining edge devices with intelligent inspection for transmission lines can fulfill the demand real‐time defect detection in field. However, there has been limited research on algorithms suitable low computational power and memory, existing primarily focuses CPU optimization. To address these issues, this paper proposes a method line endpoints based YOLO‐GSS (YOLOv8 Mosaic‐9, G‐GhostNet, S‐FPN, Spatial Intersection over Union (SIoU) modifications). First, authors improve input of YOLOv8 network using Mosaic‐9 to increase number features training phase enhance algorithm robustness. Next, introduce G‐GhostNet S‐FPN backbone neck sections while improving inference speed accuracy. Finally, modify Complete loss function SIoU further Experimental results demonstrate that compared original YOLOv8, proposed achieves 5x Nvidia Jetson NX 7.7% improvement accuracy, meeting requirements field inspections.
