Fake-licensed vehicle automatic detection method and system

Abstract

The invention provides a fake-licensed vehicle automatic detection method. According to the method, a vehicle picture is obtained based on a bayonet camera; pictures of all parts of a vehicle are detected through vehicle attributes, the pictures of the vehicle and the pictures of all parts are integrated to serve as input of a picture vehicle searching algorithm for feature extraction, the input is compared with a vehicle information base found through a license plate number recognized through a license plate, and then whether the vehicle is a fake-licensed vehicle or not is judged. The invention further provides an automatic fake-licensed vehicle detection system. The fake-licensed vehicle automatic detection method and the fake-licensed vehicle automatic detection system provided by theinvention are high in practicability, and can meet the accuracy of fake-licensed vehicle detection in most scenes; the adopted algorithm is low in complexity, high in integration and high in operationspeed, and the real-time performance can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and system for automatic detection of licensed vehicles. Background technique [0002] False license plates refer to the real license plates, and the fake plates with the same number are placed on other vehicles, so that illegal vehicles can be covered with a legal coat on the surface. Set plate cars have been banned by the state. It is clearly stipulated in the "Traffic Law of the People's Republic of China" that the flow of licensed vehicles is not allowed. Therefore, in the application process of real-world scenarios, the accuracy and real-time performance of license plate detection are crucial. [0003] At present, the existing license plate detection mainly adopts the following methods: [0004] 1. The detection method of license plates involving hardware: [0005] 1) Make unique gaps and protrusions for each license plate frame to improve the a...

AI Technical Summary

Problems solved by technology

Utilizing spatio-temporal contradictions to process and monitor bayonet monitoring data, a unified speed threshold is usually used. In the case of improper threshold setting, it is easy to cause missed detection or misjudgment of licensed vehicles.

[0011] With the expansion of the number of cars, vehicle-related crimes are becoming more and more rampant, and violations of vehicle license plate violations are frequent. Therefore, how to accurately and real-time detect illegal driving on the road with a set of license plates has become an urgent problem to be solved in this field

[0012] At present, there is no description or report of the similar technology of the present invention, and no similar data at home and abroad have been collected yet.
