Vehicle identification method, vehicle identification device and inspection system

Abstract

The invention provides a vehicle identification method and a vehicle identification device. The method includes the following steps that: whether first information contained in the electronic license plate of a vehicle is matched with second information contained in the physical license plate of the same vehicle is judged, wherein the first information and the second information are acquired by a certain inspection gate, if the first information is matched with the second information, the vehicle is judged as a legal vehicle; if the first information is not matched with the second information, first information contained in the electronic license plate and second information contained in the physical license plate of the same vehicle acquired by a plurality of inspection gates which are adjacent to the inspection gate are obtained according to the driving path of the vehicle; and whether the first information and the second information which are acquired by each inspection gate are matched with each other is judged, if the first information is not matched with the second information, the vehicle is finally judged as an illegal vehicle. According to the method, when the second information cannot be clearly identified due to poor external environment, and the first information cannot be matched with the second information, the above judgment result can be verified through judging whether the first information and the second information of the same vehicle which are acquired by the plurality of inspection gates which are adjacent to the inspection gate are matched each other, and therefore, misjudgment caused by unclear identification of the physical license plate in a vehicle recognition process can be avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a vehicle identification method, device and inspection system. Background technique [0002] At present, in the field of intelligent transportation technology, the identification of illegal vehicles, especially the identification of fake license plates, has always been a difficult problem to overcome. Generally, the investigation process is started only after the vehicle has been illegally used, such as being falsely registered, and the victim reports it. The investigation process is usually based on video image technology to screen the physical license plate information collected by the camera to find illegal vehicles. However, physical license plate recognition based on video image technology is greatly affected by factors such as the environment, lighting, and weather. In order to avoid investigation, some people will deliberately block, deface the license p...

Problems solved by technology

However, its acquisition of actual license plate (that is, physical license plate) information is based on video image technology, and the recognition based on video image technology is greatly affected by the external environment. When it is strong, the captured image effect will be poor, which will directly lead to a decrease in the recognition rate, and the accurate information contained in the actual license plate cannot be obtained. If only based on the information contained in the electronic license plate of a single bayonet and the information contained in the actual license plate If it does not match, it will be determined that the vehicle is an illegal vehicle, and there may be misjudgment
