Small target detection algorithm for traffic scenes based on improved YOLOv5-s
针对交通标志和交通灯等交通场景小目标特征不明显导致检测困难的问题,提出基于改进 YOLOv5-s的交通场景小目标检测算法.设计特征补充模块(FSM),通过进一步获取浅层细节信息对相邻的深层检测层进行特征补充,有效提高了小目标的检测效果,并通过相邻层间的矩阵运算避免了特征冗余;设计有效融合模块(EFM),分别处理特征金字塔融合时的横向浅层特征和上采样特征,缓解二者之间的特征冲突,使其更有效的融合;提出超级增强交并比(SEIOU)损失计算方式,通过添加真实框和预测框主对角之间的距离度量,改善回归效果,提升检测精度.在CCTSDB、S2TLD、TLD和 PASCAL VOC数据集上进行实验,结果表明:所提算法在精度上分别提升了 2.54%、3.62%、4.33%和 2.01%,检测速度达到了 113帧/s,适用于实际交通场景下的检测任务.
A traffic scene tiny target detection method based on enhanced YOLOv5-s was presented to address the issue that the properties of small targets in traffic scenes,such as traffic signs and traffic lights,are not readily apparent.Firstly,a feature supplement module(FSM)was designed to supplement the features of the adjacent deep detection layers by further obtaining the shallow details,which effectively improved the detection effect of small targets,and avoided feature redundancy by matrix operation between adjacent layers.Second,in order to reduce feature conflict and improve the effectiveness of the pyramid feature fusion,an effective fusion module(EFM)was created to handle the horizontal shallow feature and the upsampled feature,respectively.Then,the super enhanced intersection over union(SEIOU)loss calculation method was proposed to improve the regression effect and detection accuracy by adding the distance measurement between the main diagonal of the ground truth box and the prediction box.Finally,experiments were carried out on CCTSDB,S2TLD,the Traffic lights dataset and the PASCAL VOC dataset.According to the results,the proposed algorithm's accuracy has increased by 2.54%,3.62%,4.33%,and 2.01%,respectively,and its detection speed has reached 113 frames per second,making it appropriate for detecting jobs in real-world traffic situations.
