License plate identification error filtering method and apparatus in fake-license plate analysis

Abstract

The invention discloses a license plate identification error filtering method and apparatus in fake-license plate analysis. The method includes the steps of: obtaining a suspected license plate number according to the fake-license plate analysis; obtaining all the similar license plates corresponding to the suspected fake-license plate; obtaining all inlet gates of a target gate through gate directed digraphs; if vehicle-passing records of the similar license plate of the suspected fake-license plate appear in some inlet gate of the target gate, the vehicle-passing records of the similar fake-license plate do not appear in all the outlet gates of the inlet gate, representing the suspected fake-license plate to be an identification error; filtering the suspected fake-license plate; and artificially checking the filtered suspected fake-license plate after the suspected fake-license plate is filtered, and finally confirming whether the license plate is fake. The apparatus of the invention includes a similar license plate analysis module, a first analysis filtering module, and a second analysis filtering module. The influence of license plate identification error is effectively reduced by performing identification error filtering on the suspected fake-license plate, the work load of the final artificial check is greatly reduced, and the final fake-license plate identification accuracy is improved.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and in particular relates to a license plate recognition error filtering method and device in deck analysis. Background technique [0002] In order to improve the level of traffic management and public security control, ensure the efficient operation of roads and comprehensive traffic control, the checkpoint system based on video image recognition has been widely used. The bayonet camera on the road will take photos of each passing vehicle, and automatically obtain the recognized vehicle information such as license plate number and vehicle color through image intelligent analysis technology, and send it to the central database for unified storage. Based on these vehicle information As well as other information, it can complete various services of traffic management and public security control, and the identification of licensed vehicles is one of them. [0003] There are two main method...
