Problems solved by technology

However, this system only analyzes and detects the license plate. Although accidental occlusion will not be judged as a violation, if this phenomenon is not eliminated in time, it will have an impact on traffic automation management, which is not conducive to traffic management.

Abstract

The invention relates to the intelligent traffic control technology field and provides a license plate detection system. When a license plate is detected to be accidentally shielded, an accidental shielding phenomenon can be timely eliminated. The system comprises a license plate identification subsystem, a license plate cleaning mechanism, an induction module, a storage module and a processing module, wherein the license plate identification subsystem is used for identifying a license plate number of a vehicle, outputting a starting signal when accidental shielding is identified and outputting an alarm signal when deliberate shielding is identified; the license plate cleaning mechanism is used for cleaning the license plate which is accidentally shielded, a cleaning component is included,and the cleaning component can be used to clean the license plates of the vehicles located at different positions on a road; the induction module is used for sending an induction signal when wheels pass through; the storage module stores a corresponding relation list of each induction unit and each cleaning component; and the processing module can send a control signal to the corresponding cleaning component according to the received induction signal, and the cleaning component cleans the license plate after receiving the control signal.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a license plate detection system. Background technique [0002] License plate recognition system is an application of computer video image recognition technology in vehicle license plate recognition. License plate recognition is widely used in highway vehicle management. The license plate recognition process includes the image collection of the vehicle, and then after the license plate positioning, character segmentation, and optical character recognition, the recognition result is output to obtain the unique license plate number of each car, thereby completing the recognition process, and then through some subsequent processing methods. The realization of functions such as traffic flow control index measurement, vehicle positioning, car anti-theft, expressway overspeed automatic supervision, and red light electronic police has practical significance for main...
