Image feature comparison based counterfeit vehicle registration plate identification method

Abstract

The invention discloses an image feature comparison based counterfeit vehicle registration plate identification system which comprises a vehicle image acquisition module, a counterfeit registration plate pre-processing module and a counterfeit registration plate intensification identification module, and is characterized in that the vehicle image acquisition module is used for acquiring vehicle images and sending the images to the counterfeit registration plate pre-processing module; the counterfeit registration plate pre-processing module is provided with a vehicle type feature library and a vehicle basic library, and used for judging the type of the vehicle to be identified according to number plate area and vehicle head area, and for comparing the type with the vehicle type obtained from the vehicle type feature library through retrieval according to the vehicle number plate; when the vehicle type judged based on both the number plate area and the vehicle head area is not consistent with the vehicle type obtained from the vehicle type feature library through retrieval according to the vehicle number plate, the counterfeit registration plate pre-processing module takes the vehicle to be identified into the counterfeit registration plate suspicion library and transmits to the counterfeit registration plate intensification identification module for processing; the counterfeit registration plate intensification identification module judges whether the to-be-identified vehicle with the plate taken into the counterfeit registration plate suspicion library is the set of sign vehicle according to the vehicle number plate reissue condition, the intensity of license plate fuzzy coefficient of the to-be-identified vehicle image, and the intensity of the error clustering factor of license plate number.
