Problems solved by technology
According to the existing highway monitoring requirements, if we want to achieve full coverage and seamless monitoring, the camera density will be very high and the investment cost will be very expensive.
[0003] In addition, the existing traffic road condition monitoring screen can only display the snapshot images of the monitored road section, and the display content is single. Real-time acquisition of monitoring images on the expressway, and it is also impossible to identify the path of vehicles based on the monitoring images

The present invention proposes a path recognition method based on a four-dimensional real-scene traffic simulation road condition perception management system. The capture camera collects vehicle photos, and sends the vehicle tracking and positioning information and vehicle photos to the central server; extracts the vehicle feature information from the vehicle photos, compares them with the local preset 3D vehicle model library, and performs fuzzy matching to extract the corresponding vehicle 3D model, and fused the vehicle tracking and positioning information with the 3D model of the vehicle; superimposed the fused 3D model of the vehicle with the 3D GIS map to realize 4D real-world road condition simulation, and obtained the position of the vehicle at different time nodes by setting the time interval Information, the point-line connection technology can be used to obtain the precise vehicle path information that you want to know, so as to achieve the purpose of precise vehicle path identification.
