License plate recognition method and device, terminal and readable storage medium

Abstract

The invention belongs to the technical field of image recognition, and particularly relates to a license plate recognition method and device, a terminal and a readable storage medium. The method comprises the steps that a license plate image of a license plate to be recognized is acquired, and the license plate to be recognized is a one-row or multi-row license plate; inputting the license plate image into a preset convolutional neural network to obtain character probability distribution corresponding to each part of a to-be-recognized license plate output by the preset convolutional neural network; and determining the license plate content of the to-be-identified license plate according to the character probability distribution corresponding to each part of the license plate, thereby realizing one-time identification of one-line license plate content and multiple-line license plate content through the preset convolutional neural network, improving the license plate identification efficiency, and being beneficial to meeting the requirement of rapid license plate identification nowadays.

Description

technical field [0001] The present application belongs to the technical field of image recognition, and in particular relates to a license plate recognition method, device, terminal and readable storage medium. Background technique [0002] With the rapid development of intelligent transportation, the society's demand for license plate recognition is getting higher and higher. For example, in scenarios such as monitoring traffic flow, automatic ETC charging, and traffic control, it is necessary to quickly identify the content of the license plate. [0003] In practical applications, license plates often have single-line license plates and double-line license plates. In the prior art, for double-line license plate recognition, it is often necessary to divide the double-line license plate into upper and lower two-line license plates, input them into the convolutional neural network for feature extraction, and then input the extracted two features into the recurrent network F...
