Four-dimensional live-action traffic road condition perceiving and early-warning monitoring management system based on radar tracking and positioning

Abstract

The invention provides a four-dimensional live-action traffic road condition perceiving and early-warning monitoring management system based on radar tracking and positioning. According to the four-dimensional live-action traffic road condition perceiving and early-warning monitoring management system, a tracking and positioning technology, a license plate snapping technology, a vehicle and pedestrian three-dimensional simulation technology, a road monitoring technology, an early-warning and alarming technology, a traffic condition simulation technology, a network communication technology, a meteorological simulation technology, a computer graphic technology, a video rendering technology, a three-dimensional high-precision GIS map technology, a virtual reality fusion technology, a vehicle-road collaborative technology and a navigation technology are perfectly fused together; and through the system, the various demands of road traffic operation managers for road real-time monitoring orarea monitoring and the information demands of traveling of drivers and passengers for real-time and real traffic conditions are greatly met, and the various drawbacks which are imperfect and cannot be solved in an existing monitoring system are overcome, so that the management efficiency of the road managers is improved, the firm foundation is laid for automatic management of roads, and the important safety guarantee is also provided for traveling vehicles on the road.

AI Technical Summary

Problems solved by technology

Also there will be this situation in haze weather, raining, snowing weather or heavy fog weather, and the fixed-point weather detection device will seem powerless under this condition

In addition, although smoke sensors are also deployed in the tunnel, they are all fixed-point layouts, and the harmful gas detection and environmental detection in the tunnel are all fixed-point detection, and the number is very small, which can only one-sidedly reflect a certain node and or a The data of the section cannot represent the accurate data of a large area in a continuous area, especially once a traffic accident occurs in the tunnel, this kind of data is more important. Obtaining continuous, accurate and reliable data early is helpful for emergency warning and life saving. Provide technical support, which is very important for a traffic manager

[0004] Furthermore, at this stage, traffic radar and security radar detection equipment mainly use directional methods for real-time tracking and detection. The main disadvantage is that the tracking distance is only more than 100 meters, and the number of tracking targets is small and only 30 objects are tracked. It is mainly used for traffic data collection, Speed ​​law enforcement, signal triggering and other data collection, security radar is mainly used for pedestrian intrusion perimeter protection, etc., but radar detection equipment has many advantages such as being unaffected by light, working 24 hours a day, and accurate detection.
