Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings, and this embodiment does not constitute a limitation to the present invention.

[0018] Such as figure 1 As shown, a local camera 1 and a facing camera 2 are installed on the same traffic pole, and the models of the two cameras are the same. The captured information is the tail data of the motor vehicle. The facing camera 2 performs video and image captures of passing vehicles on the same side of the road, and the captured information is the frontal data of motor vehicles. The camera 1 in the direction and the camera 2 in the direction 2 are devices of the front-end capture unit.

[0019] Such as figure 2 As shown in the figure, a system for identifying the license plate of a smoky vehicle by capturing before and after, the front-end capture unit is respectively connected with the smoky vehicle identification unit, the motor veh...

Abstract

The invention discloses a system for identifying license plates of black smoke vehicles by front and rear snapshotting. A front-end snapshotting unit is respectively connected to a black smoke vehicle identification unit, a motor vehicle license plate identification unit and a motor vehicle license plate verification unit, the black smoke vehicle identification unit, the motor vehicle license plate identification unit and the motor vehicle license plate verification unit are connected to a data processing unit, and the data processing unit is connected to a data storage unit. The system monitors a plurality of lanes by means of a forward camera and a backward camera, consequently, the problem that license plates cannot be identified when detection is carried out on black smoke vehicles is solved, and the black smoke vehicle license plate identification rate is effectively increased.

Description

technical field [0001] The invention relates to the field of environmental technology, in particular to a system and method for identifying license plates of smoky vehicles by snapping back and forth. Background technique [0002] Smoky vehicles are typical representatives of high-pollution vehicles, which usually emit thick black smoke. Therefore, the detection of exhaust gas, which represents the content of soot, is widely used in the evaluation of diesel engine emission pollution. At present, two methods are commonly used to measure the exhaust smoke of diesel engines: the remote sensing detection method of black smoke vehicles and the intelligent visual recognition method. Both detection methods need to recognize the vehicle license plate, but the object vehicle detected by the black smoke vehicle intelligent visual recognition method is a multi-lane vehicle on the road, and the specific license plate recognition method generally uses a set of cameras corresponding to tw...
