Abstract

The invention provides a method and system for license plate recognition, and equipment to provide an LPR manner that has a low requirement for image resolution and is effective. The system (100) forlicense plate recognition includes first equipment (10) configured to capture an image of a vehicle (50), and second equipment (20) configured to obtain an image of a license plate (60) from the imageof the vehicle (50), recognize the license plate (60) using a model, where the model is trained using an annotated image of the license plate, and identify a license plate (60) using the model, and the annotated image is generated based on the image of the character and the image of the scene. Since the model is trained using the generated annotated images of the license plate, time-consuming manual annotation can be omitted, which saves time and improves efficiency. A well-trained and accurately-labeled model is utilized, and even the license plate can be recognized based on a low-resolutionimage.

Description

technical field [0001] The present invention relates to object recognition technology, and more particularly to a system, method and device for license plate recognition (LPR). Background technique [0002] LPR is a technology that recognizes license plates from images, partitions them, and recognizes characters. Traditional LPR technology requires high image resolution, and the correction recognition rate is not high. Contents of the invention [0003] In one solution to the license plate recognition problem, an efficient LPR approach with lower image resolution requirements is provided. [0004] According to a first aspect of the present disclosure, a system for license plate recognition is provided, comprising: [0005] - a first device configured to: capture an image of the vehicle, obtain an image of a license plate of the vehicle from the image of the vehicle, and send the image of the license plate to the second device; [0006] - A second device configured to re...
