Quick vehicle detection system

The invention provides a rapid vehicle detection system. The rapid vehicle detection system comprises a real-time video stream input unit, a target intelligent detection unit, a vehicle state judgmentand early warning unit, a three-dimensional scene reconstruction unit and a data storage and invoking unit. The real-time video stream input unit is used for collecting monitoring real-time video streams of target vehicles at different angles and sending the monitoring real-time video streams to the target intelligent detection unit. The target intelligent detection unit is used for detecting whether a target in a monitoring area is a vehicle or not; the vehicle state judgment and early warning unit is used for detecting whether a vehicle in the monitoring area has abnormal behaviors of overspeed and stagnation or not and sending out warning information in time; the three-dimensional scene reconstruction unit is used for reconstructing and restoring vehicles and trace positions of an original scene of an accident
