System for automatically simulating and restoring expressway events through high-precision map

Abstract

The invention relates to the technical field of video analysis, in particular to a system for automatically simulating and restoring highway events through a high-precision map. The system comprises a monitoring camera unit, the output end of the monitoring camera unit is connected with an accident area positioning unit, the output end of the accident area positioning unit is connected with an involved road section map extraction unit and an involved vehicle identification unit, and the output end of the involved vehicle identification unit is connected with a u3d accident simulation unit. According to the invention, the accident area positioning unit is used for positioning an accident place, positioning information is transmitted to the involved road section map extraction unit, the involved road section map extraction unit is used for accurately extracting map information of an accident road section, and meanwhile, the involved vehicle unit is used for identifying involved vehicle information. And the identification information is transmitted to the u3d accident simulation unit, the u3d accident simulation unit carries out analogue simulation on the driving track and the real position of the vehicle, the whole process of the accident is restored, and traffic management personnel can conveniently determine the cause of the accident.

Description

technical field [0001] The invention relates to the technical field of video analysis, in particular to a system for automatically simulating and restoring expressway events through high-precision maps. Background technique [0002] A traffic accident refers to an event in which a vehicle on the road causes personal injury or death or property damage due to fault or accident. Resisting natural disasters, the current traffic accidents are mainly based on the preservation and analysis of recorded videos, and the restoration of accidents is mainly based on manual analysis or modeling, which takes a long time and makes it difficult to dynamically display the accident process in a timely manner. Contents of the invention [0003] The purpose of the present invention is to provide a system for automatically simulating and restoring expressway events through high-precision maps, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to...
