A vehicle identification method, device and inspection system

Abstract

The vehicle identification method and device provided by the present invention first judge whether the first information contained in the electronic license plate of the same vehicle collected by an inspection checkpoint matches the second information contained in the physical license plate, and if they match, it is judged that the vehicle is a legal vehicle, If not, according to the driving path of the vehicle, obtain the first information contained in the vehicle's electronic license plate and the second information contained in the physical license plate collected by multiple checkpoints adjacent to the inspection checkpoint, and then judge each checkpoint Whether the collected first information matches the second information, and if they do not match, it is finally determined that the vehicle is an illegal vehicle. When the external environment is bad and the acquired second information cannot be identified clearly, and the first information cannot be matched with the second information, the first information and the second information of the same vehicle collected by the checkpoint adjacent to the inspection checkpoint can be judged Check whether the above judgment results are matched or not, avoiding the misjudgment that may occur due to unclear recognition of the physical license plate during the vehicle recognition process.

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
