Method and Device for License Plate Positioning

摘要

Embodiments of the present application provide a license plate location method and apparatus. The method includes: acquiring a to-be-located license plate image; sending the to-be-located license plate image to a target network for license plate location; wherein, the target network comprises a feature extraction layer and a regression layer; extracting, by the feature extraction layer, a feature value of the to-be-located license plate image, and sending the feature value to the regression layer; acquiring a combination of a license plate frame area and a license plate character area, which is obtained by the regression layer based on the feature value; and determining a license plate area of the to-be-located license plate image based on a location area corresponding to the acquired combination. The target network is pre-trained by sample license plate images; the sample license plate images include positive sample license plate images, and the positive sample license plate images include combinations of license plate frame areas and license plate character areas. With the technical solutions according to embodiments of the present application, the accuracy of the license plate location can be improved.
