License plate recognition method, license plate recognition device, license plate recognition equipment and medium

Abstract

The invention discloses a license plate recognition method, a license plate recognition device, license plate recognition equipment and a medium. The license plate recognition method comprises the steps of preprocessing a vehicle image to obtain a to-be-recognized license plate image and a license plate type of the to-be-recognized license plate image; under the condition that the license plate type of the to-be-identified license plate image indicates multiple lines of license plates, performing type conversion on the to-be-identified license plate image of the multiple lines of license platetypes to obtain a license plate image of a single line license plate type; and identifying the license plate image of the one-way license plate type to obtain a license plate number. The multi-line license plate is converted into the single-line license plate, so that the multi-line license plate can be simply and efficiently identified.

Description

technical field [0001] The present disclosure relates to the field of intelligent transportation, and more specifically relates to a license plate recognition method, a license plate recognition device, a license plate recognition device and a medium. Background technique [0002] With the continuous deepening of deep learning in the civil and commercial fields, vehicle recognition, as a key technology in intelligent transportation systems, is also facing higher requirements in vehicle detection, especially for the detection and recognition of multiple license plates. Based on the variety of license plate types and the huge difference between single-line license plates and multi-line license plates, the existing technology relies on multi-line text detection technology to detect and locate each line of the multi-line license plate when recognizing multi-line license plates, and then uses the single-line recognition model to identify each line one by one. Rows are identified ...

AI Technical Summary

Problems solved by technology

The license plate recognition method provided by this disclosure can efficiently identify various types of license plates, solve the problem that a large number of indexing consumes human resources in double-line license plate recognition, and the problem of long processing time caused by multiple calls to the recognition model improves the detection accuracy and efficiency. , and the method has good robustness
