Path recognition method based on four-dimensional live-action traffic simulation road condition awareness management system

Abstract

The invention provides a path recognition method based on a four-dimensional live-action traffic simulation road condition awareness management system. The path recognition method comprises the stepsthat a radar sensor arranged on the road side acquires tracking and positioning information of each passing vehicle and synchronously triggers a vehicle license plate snapping camera, and the vehiclelicense plate snapping camera acquires vehicle photos and sends the tracking and positioning information and the vehicle photos of the vehicles to a center server; vehicle feature information in the vehicle photos is extracted and compared with a local preset three-dimensional vehicle model library, fuzzy matching is conducted to extract corresponding three-dimensional vehicle models, and the vehicle tracking and positioning information is fused with the three-dimensional vehicle models; and the three-dimensional vehicle models obtained after fusion are superimposed with a three-dimensional GIS maps to achieve four-dimensional live-action road condition simulation, position information of the vehicles at different time nodes is acquired by setting a time interval, precise vehicle path information that a user wants to know can be acquired by adopting a point-line connection technology, and then the purpose of precise vehicle path recognition is achieved.

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
