YOLOv5s-D: A Railway Catenary Dropper State Identification and Small Defect Detection Model
High-speed railway catenaries are vital components in railway traction power supply systems. To ensure stable contact between the pantograph and the catenary, droppers are positioned between the messenger wire and contact line. The failure of one or more
