Problems solved by technology

However, most of the existing algorithms directly use the general target detection network for traffic flow detection (Chen Jiaqian, Jin Junhong, Wang Wenyuan, Lu Yingjie. Traffic flow detection based on YOLOv3 and DeepSort[J]. Acta Metrology, 2021,42(06):718-723 .), leading to excessive network model parameters and calculation requirements, making it difficult to deploy in the application scenario of smart light poles

Abstract

The invention relates to a vehicle flow detection method and system, belonging to the technical field of vehicle flow detection. In the traffic flow detection method provided by the present invention, the image sequence of the visible light traffic flow video on the road surface to be detected is input to the L-YOLOv5 network model to obtain the vehicle detection result, and then, according to the statistics of the vehicle detection results, the visible light traffic flow video on the road surface to be detected is obtained. Finally, the traffic flow level is determined according to the number of vehicles, so that the traffic flow detection effect can be improved while reducing the calculation requirements.

Description

technical field [0001] The invention relates to the technical field of traffic flow detection, in particular to a traffic flow detection method and system. Background technique [0002] Smart light poles are an indispensable and important part of future urban infrastructure. By installing a traffic flow detection system on smart light poles, the perception and collection of traffic information in the city can be realized, thereby providing reliable data for urban traffic planning and management. Support, effectively improve transportation efficiency, ensure traffic safety, and improve the transportation environment. [0003] With the development of computer vision technology, video-based traffic flow detection methods have been widely researched and applied. However, most of the existing algorithms directly use the general target detection network for traffic flow detection (Chen Jiaqian, Jin Junhong, Wang Wenyuan, Lu Yingjie. Traffic flow detection based on YOLOv3 and Deep...
