Uncertain information-based method for screening vehicles with false license plates

Abstract

The invention relates to an uncertain information-based method for screening vehicles with false license plates. The method comprises the steps of (1) acquiring the record data of vehicles that pass through a bayonet and the registration information data of the vehicles, and conducting the data cleaning; (2) conducting the space-time filtering treatment on the cleaned record data set of vehicles that pass through the bayonet to obtain a new record data set of vehicles that pass through the bayonet; (3) calculating to obtain a record data set of suspicious vehicles that pass through the bayonet and a record data set of normal vehicles that pass through the bayonet; (4) calculating the trace matching degree omega of suspicious vehicles and normal vehicles based on the Spark method; (5) calculating the vehicle similarity theta of suspicious vehicles and normal vehicles; (6) calculating the suspicion degree of the false license plates of the suspicious vehicles based on the trace matching degree omega and the vehicle similarity theta, and obtaining a screening result for vehicles with false license plates. Based on the above method, the traffic management department is facilitated to actively find out and investigate vehicles with false license plates, rectify and reform vehicles with heavily stained license plates. Meanwhile, the method is convenient in deployment, and wide in applicability.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for screening fake license plates based on uncertain information. Background technique [0002] In recent years, with the rapid development of my country's national economy, the number of motor vehicles has continued to grow rapidly every year, and various traffic violations have also increased. Among all kinds of traffic laws and regulations, vehicle "false license plate" and "fake license plate" are illegal acts with serious harm. The phenomenon of "false license plates" of vehicles refers to the phenomenon that vehicles forge or alter motor vehicle license plates, and illegally use license plate numbers that do not exist in the vehicle registration information of motor vehicle management offices. The phenomenon of "fake cards" is a serious hazard. Criminals use "fake cards" to evade urban traffic control measures, evade responsibility for traffic accidents, ...

Problems solved by technology

[0006] The above methods have some disadvantages in actual application: the detection and identification method based on the Internet of Things needs to install detection equipment for motor vehicles, and manually check or deploy wireless monitoring points on the road, which is expensive and difficult to popularize at present; The method of information comparison is easily affected by the light and environment, and the accuracy rate is not high; the method of directly using the vehicle license plate for comparison is simple and effective, but it is easily affected by the error rate of bayonet recognition. With a recognition error rate of 3%, 30,000 vehicle license plates out of 1 million vehicle passing records may be misidentified as "fake license plates"

If you think that these misidentified vehicles are "fake" vehicles, on the one hand, it does not conform to the actual situation, and on the other hand, it will bring great inconvenience to the subsequent video verification and deployment.
