摘要:
针对在阴天、雨天、夜晚等复杂天气情况下,车辆目标检测受到光照、雨雪、沙尘等因素影响,出现错检、漏检等问题,提出了一种YOLOv10-vehicle目标检测算法。首先,设计了一种新的注意力机制模块WT-PSA,在复杂天气下提高模型对车辆目标的关注度;其次,改进了SPPF模块,通过引入平均池化操作,改善因最大池化操作导致的特征信息提取不足问题;然后,设计了改进的C2f-OD模块,提升主干网络提取图片特征信息的能力;最后,将模型损失函数替换为Focal EIoU,以加快收敛速度并降低损失值;在车辆数据集UA-DETRAC上进行对比实验,改进后的算法平均准确率(mAP@0.5)相较原算法提升了5.1%,证明了YOLOv10-vehicle算法在复杂天气、恶劣天气下车辆检测方面的优越性。同时,在VOC公共数据集上进行实验验证,YOLOv10-vehicle算法在检测车辆目标时检测精度提高了2.8%,证明了本文改进算法的泛化性。
