Abstract: Aiming at the problems of strong scene dependence and poor real-time performance in traditional vehicle detection methods, a front vehicle recognition system based on YOLOv7 deep learning model is proposed. Firstly, the limitations of traditional vehicle detection methods are analyzed, including two types of methods based on image processing technology and feature extraction. Then, it introduces the theoretical basis of deep learning, focusing on the system framework of YOLOv7 model. Finally, it carried out experiments on COCO data set. The results show that the average accuracy of YOLOv7 model in vehicle recognition task reaches 69.7%, which significantly improves the detection accuracy and real-time performance compared with traditional methods. This study provides an effective technical solution for vehicle detection in intelligent transportation systems.
