Abstract

The invention provides a vehicle track information acquisition method and device, equipment and a storage medium. The method comprises the steps that first vehicle information detected by a first roadside device is acquired, second vehicle information detected by at least one second roadside device is acquired, and the first roadside device and the at least one second roadside device are arranged at different positions of the same road node; and track information of at least one vehicle is generated according to the first vehicle information detected by the first roadside device and the second vehicle information detected by the at least one second roadside device. According to the method provided by the invention, the road side equipment is arranged at the junction of the road and the road nodes and near the junction to detect the road vehicle information, so that the track information of the vehicle is quickly and accurately obtained.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, and in particular to a method, device, equipment and storage medium for acquiring vehicle trajectory information. Background technique [0002] With the development of the city, the traffic in the city becomes more and more complex, and it is necessary to control the traffic in the city. [0003] In the prior art, cameras can be installed on the road to collect images of roads and vehicles; by analyzing the images, vehicle trajectories can be obtained, so as to monitor traffic. [0004] However, in the prior art, the above-mentioned image analysis method requires complex image processing algorithms, and the analysis and recognition speed is relatively slow, and vehicle trajectory information cannot be obtained quickly. Study the application of ETC data in urban traffic management, and use it as one of the important components of the road perception system. Through th...
