Abstract

The invention relates to a license plate recognition method and device, computer equipment and a computer readable storage medium, and the method comprises the steps: obtaining a video, and detectinga target license plate image in an image frame of the video; performing quality classification on the detected preset attribute of the target license plate image in each image frame to obtain a quality classification result; determining a quality score of the target license plate image in each image frame at least according to the quality classification result; and screening the target license plate image according to the quality score, and performing license plate recognition according to the screened target license plate image. Through application of the method and the device, the problem that a license plate recognition technology in related technologies is relatively high in computing resource load is solved, and the technical effect of reducing the computing resource load is realized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular to a license plate recognition method, device, computer equipment, and computer-readable storage medium. Background technique [0002] With the development of people's life and the advancement of science and technology, the number of motor vehicles continues to increase, and intelligent transportation systems are playing an increasingly important role. License plate recognition technology is an important part of modern intelligent transportation systems. Relying on the rapid iteration of algorithms and Hailiang video data collected by video surveillance, artificial intelligence has gradually landed in the field of license plate recognition technology. [0003] As the unique identification of a vehicle, the license plate information can confirm the identity of the vehicle. Therefore, the license plate recognition technology plays an important ...
