The performance improvement of traffic sign recognition can not only improve the performance of unmanned driving systems,intelligent navigation systems and assisted driving systems,but also provide reference for other small target detection technologies.Compared with yolov5s,which is widely used for object detection,yolov8s,the mAP50 of yolov8s is improved by 3.1%,and the detection speed meets the real-time requirements,so the traffic sign recognition based on yolov8s can improve the detection accuracy on the basis of meeting the real-time requirements of detection.
