Abstract

The invention discloses a low-illumination imaging license plate recognition method, and the method comprises the steps: inputting an original license plate low-illumination image obtained through a camera module into a multi-scale context aggregation network based on deep learning, and carrying out the image processing, so as to obtain a license plate image with an improved recognition degree; performing license plate positioning and license plate inclination correction processing on the license plate image to obtain a positioned license plate image; segmenting the positioned license plate image into a plurality of license plate characters; and recognizing each license plate character. The invention further discloses a license plate recognition system, computer equipment and a storage medium. According to the technical scheme, the problems that in an existing method, image details are not clear enough, recognition details are not accurate enough, and the processing effect often changes greatly according to different environments are solved.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a low-illuminance imaging license plate recognition method, a license plate recognition system applying the low-illuminance imaging license plate recognition method, computer equipment and a computer-readable storage medium. Background technique [0002] With the development of computer vision, digital image processing technology and intelligent transportation technology, the application of license plate recognition technology in the field of intelligent transportation is becoming more and more extensive. There are more and more products related to license plate recognition on the market. However, there is still a common problem: the existing license plate recognition system has relatively high image quality requirements. However, in complex application environments, the image quality often obtained Low, unable to meet the requirements of the system, resulting in low lice...
