Problems solved by technology

The Alpr algorithm is aimed at foreign license plates. Foreign license plates only have numbers and letters, so the OCR algorithm can only detect and recognize the letters and numbers of Chinese license plates and cannot recognize Chinese characters such as provinces in Chinese license plates.

Abstract

The invention discloses a model training method and a model training device for improving the automatic detection and recognition rate of Chinese characters of a license plate, a license plate recognition method and a storage medium, and belongs to the technical field of automatic recognition. The method mainly comprises a model training step. According to the method, Chinese characters, numbers and letter parts of the Chinese license plate can be recognized, and the problem that the OCR algorithm can only detect and identify letters and numbers of the Chinese license plate and cannot identifyprovinces and other Chinese characters in the Chinese license plate is solved.

Description

technical field [0001] The invention relates to the technical field of automatic identification, in particular to a model training method, a model training device, a license plate recognition method and a storage medium for improving the automatic detection and recognition rate of Chinese characters of a license plate. Background technique [0002] The full name of Alpr is Automatic License Plate Recognition, that is, automatic license plate recognition without scene constraints. Its working process is to recognize the car first, cut each car into a picture, then perform license plate detection and correction, and finally get the license plate that is almost square, and then the license plate The letters and numbers in the license plate are detected and recognized, and the license plate characters are sorted according to the position information. [0003] The algorithm to recognize the characters in the license plate is named OCR algorithm in the Alpr algorithm. The Alpr al...
