Abstract

The embodiment of the invention provides a system and method for identifying a dangerous vehicle in a tunnel. The system comprises two or more laser radar units, a camera capturing unit and a data processing unit; the laser radar units, the camera capturing unit and an information prompt unit are connected with the data processing unit; the laser radar units and the camera capturing unit are arranged on the inner wall of the tunnel successively in the vehicle traveling direction; the laser radar units are used for collecting vehicle data information; the data processing unit is used for identifying whether a vehicle is the dangerous vehicle or not according to the vehicle data information, and if the vehicle is the dangerous vehicle, a capturing instruction is sent to the camera capturingunit; the camera capturing unit is used for capturing a picture of the vehicle according to the capturing instruction so as to obtain vehicle capturing information; and the data processing unit is further used for constructing vehicle identifying result information according to the type to which the dangerous vehicle belongs, the danger type and vehicle capturing information. The dangerous vehiclecan be accurately identified.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent transportation, and in particular to a system and method for identifying dangerous vehicles in a tunnel. Background technique [0002] With the rapid development of the economy and the surge in traffic volume, hazardous chemical transport vehicles are highly valued in the safety management and operation of tunnels due to their explosive, flammable, and toxic characteristics, and vehicles that are ultra-wide, ultra-high or speeding Driving in the tunnel also threatens the safety of the tunnel. These vehicles constitute a dangerous vehicle in the tunnel. Therefore, monitoring the operation of vehicles in the tunnel is the top priority in managing the safe operation of the tunnel. [0003] In the prior art, the identification method of dangerous vehicles in the tunnel is mainly the method of video surveillance, and the license plate information of the vehicle and keywo...
