摘要： 针对目前车辆实时检测中存在定位不准确、检测精度低等问题，采用了一种以Darknet-53为骨架网络的YOLOv3车辆检测算法，将该算法模型在标准数据集Pascal-VOC2012上进行训练，以拍摄的西安南二环路的图片作为测试集进行测试。实验结果表明，YOLOv3算法的检测精度达到84.9%，相比于SSD算法，其检测精度提高了11.3%，检测速度提高了3.8 f/s。因此YOLOv3算法检测精度更好，检测速度更快，能准确地检测出图像中的车辆信息，满足车辆实时检测的要求。

Research on vehicle detection algorithm based on deep learning

Abstract： In view of the current real-time detection of vehicles, there are problems such as inaccurate positioning and low detection accuracy. This paper uses a YOLOv3 vehicle detection algorithm with Darknet-53 as the skeleton network. The algorithm model is trained on the standard data set Pascal-VOC2012, and the pictures of Xi′an South Second Ring Road are taken as the test set for testing. Experimental results show that the detection accuracy of YOLOv3 algorithm reaches 84.9%, which is 11.3% higher than that of SSD algorithm. The detection speed has also increased by 3.8 f/s. Therefore, YOLOv3 algorithm has better detection accuracy and faster detection speed, can accurately detect the vehicle information in the image, and meet the requirements of real-time vehicle detection.
