A license plate recognition method, device, equipment and storage medium for a workstation vehicle

Abstract

The present application discloses a license plate recognition method, device, equipment and storage medium for a vehicle at a station. The method includes: judging whether there is a target vehicle in the target detection area in the shooting picture; When the feature or staying feature is detected, the license plate image of the target vehicle is collected; when the target vehicle is detected to arrive at the target station, the license plate number of the target vehicle is determined according to each license plate image. This method is to obtain the license plate image of the target vehicle from the time the target vehicle enters the target detection area to the process of arriving at the target station. The way of the license plate image, this method can increase the probability of obtaining the license plate image of the target vehicle; and this method uses a plurality of license plate images collected to determine the license plate number of the target vehicle, which can greatly improve the ability to determine the target located on the target station. The accuracy of the vehicle's license plate number.
