Aiming at the pr.blem that the cur.ent tr.ffic safety helmet detection model can't balance the accur.cy of detection with the size of the model and the poor.gener.lization of the model, a method based on impr.ving you only look once ver.ion 5(YOlOv5) is pr.posed. By incor.or.ting the lightweight Ghost Net module into the YOlOv5 backbone networ., we effectively r.duce the model size. The addition of the r.ceptive fields block(r.B) module enhances featur. extr.ction and impr.ves the featur. acquisition capability of the lightweight model. Subsequently, the high-per.or.ance lightweight convolution, GSConv, is integr.ted into the neck str.ctur. for.fur.her.model size compr.ssion. Mor.over. the baseline model's loss function is substituted with efficient inser.ion over.union(EIoU), acceler.ting networ. conver.ence and enhancing detection pr.cision. Exper.mental r.sults cor.obor.te the effectiveness of this impr.ved algor.thm in r.al-wor.d tr.ffic scenar.os.
