Method and system for fusing radio frequency identification and vehicle license plate recognition

Abstract

The invention discloses a method for fusing radio frequency identification and vehicle license plate recognition. The method comprises the step of license plate recognition and the step of license plate fusion. According to the license plate recognition, a radio frequency identification system conducts collection and recognition on motor vehicle license plate information through a reader-writer, wherein the motor vehicle license plate information is stored in vehicle-mounted radio frequency identification tags; a vehicle license plate recognition system conducts information collection and recognition on motor vehicle license plates through a camera device, and respectively records license plate information which is successfully recognized and time information at the moment of successful recognition. According to the license plate fusion step, a table of similarity among characters of the motor vehicle license plates is built, fusion recognition is carried out on the motor vehicle license plate information obtained from the radio frequency identification system and the vehicle license plate recognition system based on the table of similarity, and a final recognition result is output.

Description

technical field [0001] The present invention relates to a data fusion method, in particular to a method for synthesizing the motor vehicle license plate recognized by the radio frequency identification system and the motor vehicle license plate recognized by the license plate recognition system in the application of intelligent transportation, and to realize this system of methods. Background technique [0002] Radio Frequency Identification (RFID) technology has the advantages of fast identification, long-distance identification, multi-target identification and non-line-of-sight identification, and is widely used in vehicle identification in the field of intelligent transportation. By installing a radio frequency identification tag with a motor vehicle number plate on the motor vehicle and installing a radio frequency identification reader above the road, when the motor vehicle passes through the radio frequency identification reading and writing work area, the information ...
