License plate number recognition method and device, electronic equipment and storage medium

Abstract

The invention relates to the technical field of artificial intelligence, and discloses a license plate number recognition method, and the method comprises the steps: detecting a license plate target frame of a to-be-recognized license plate image by a pre-trained license plate target frame detection model; detecting the license plate key points of the license plate target frame by using a pre-trained key point detection model; intercepting the license plate on the to-be-recognized license plate image according to the license plate key points to obtain a target license plate; and recognizing license plate characters of the target license plate by using a pre-trained license plate character recognition model to obtain license plate number information. The invention further provides a licenseplate number recognition device, electronic equipment and a storage medium. In addition, the invention also relates to a blockchain technology, and the to-be-recognized license plate image can be stored in a blockchain. The method can improve the recognition efficiency of license plate number recognition.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, and in particular, to a license plate recognition method, device, electronic device and computer-readable storage medium. Background technique [0002] With the increasing development of AI technology, intelligent technology has been involved in all aspects of life. Among them, license plate recognition belongs to a core technology in the intelligent transportation system. It acquires images containing license plates and uses deep learning networks to obtain license plates Character recognition is performed on the image of the vehicle, so as to obtain the license plate information, which greatly facilitates the management of the vehicle by the relevant personnel and the system. [0003] At present, the main problems of license plate recognition are as follows: 1. For obtaining images containing license plates, the license plate cannot be detected in many environments, such...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly the following problems about license plate recognition: 1. For the acquisition of license plate images, the license plate cannot be detected in many environments, for example, the angle of the license plate is not correct, the environment is too bright or too dark, the license plate is too small or too large in the picture, etc., resulting in The license plate position detection efficiency of the license plate image is low; 2. The license plate characters in the license plate image need to be segmented before the license plate character recognition can be performed, resulting in low efficiency of the license plate character recognition of the license plate image

[0004] Therefore, the current license plate recognition method mainly has the problem of low efficiency of license plate recognition.
