Beschreibung
Zusammenfassung:	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 iden
