AI Technical Summary

Problems solved by technology

Although the license plate recognition technology has achieved good development, due to the influence of factors such as shooting angle and environment, the captured license plate is not clean and tidy, and the square is appearing in the receptive field. In addition, the characters between 0 and D , 8 and B, 7 and T and other similar characters are easy to be misrecognized, so how to improve the accuracy of similar character recognition between license plates has practical value

Abstract

The invention discloses a license plate recognition method. The method comprises the following steps: acquiring to-be-recognized image data; inputting the to-be-recognized image data into a license plate recognition model for recognition to obtain a first recognition result; judging whether a single character in the to-be-recognized image data meets a preset condition or not; if so, taking the first recognition result as a final recognition result; if not, inputting the to-be-recognized image data into a license plate processing model to obtain a second recognition result; and obtaining the final recognition result based on the first recognition result and the second recognition result, so that license plate recognition with similar characters can be realized, and the recognition accuracy is relatively high.

Description

technical field [0001] The invention relates to the technical field of image detection, and more specifically to a license plate recognition method and system. Background technique [0002] As an important part of intelligent traffic monitoring and management system, automatic license plate recognition has always been a research hotspot. License Plate Recognition System (LPRS) plays an important role in traffic road information management, greatly improving the efficiency of traditional management models. The license plate detection and recognition system is an indispensable part of the city brain system and has a wide range of application scenarios. For example, through the camera at the intersection to capture illegal vehicles, to track illegal and criminal vehicles, toll stations, parking lots, ports, and license plate recognition systems in residential areas, etc. [0003] As an important part of intelligent traffic monitoring and management system, automatic license p...
