A method for detection, deployment and control of licensed vehicles

Abstract

A method for checking and controlling vehicles with license plates, comprising the following steps: 1) data extraction; 2) calculating the lower limit of travel time; 3) using the license plate number fast hash algorithm to identify vehicles; 4) calculating the degree of suspicion of vehicles with license plates: And the data with the same license plate number, to judge whether it is a suspected car with a license plate, the steps are as follows: calculation of time suspiciousness, calculation of suspicious degree of aggregation, 5) selection of the best control point: sort the suspicious degree of vehicle license plate to obtain a list of suspicious licensed vehicles , when the suspicious degree is greater than the set threshold, it is judged as a suspicious licensed vehicle; the trajectory analysis of the suspicious licensed vehicle is carried out, and the vehicle trajectory table is established according to the checkpoint number and the elapsed time, and the checkpoint number that has passed the most times in the same time slot as the best control point. The invention provides a fast calculation speed, high recognition accuracy, good reliability, and a method for detecting, checking and controlling decked vehicles with the function of deployment, control and interception.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and relates to a detection method for vehicles with false license plates, in particular to a method for detection, inspection and deployment of vehicles with false license plates. Background technique [0002] Cars with license plates, commonly known as clone cars, refer to vehicles that go on the road through forged or illegally obtained license plates and driving licenses of other vehicles. Most of the license plate cars come from unknown sources and have no legal procedures, such as illegal smuggled cars, stolen cars, scrapped cars, etc. It is impossible for these vehicles to apply for legal license plates, and they have to apply license plates to drive on the road. At the same time, if you use other number plates, you can drive illegally at will. Even if you are caught by the electronic police, you will not be found out, and you will get away with it, which will cause great harm to ...
