- Abstract
With the development of science and technology and the development of transportation industry, the intelligent traffic management system is becoming more and more updated. A vehicle license plate recognition system has been widely used in people's lives. In this paper, four steps of license plate recognition and their corresponding algorithms are analyzed and studied: the license plate image preprocessing part includes image de-fogging pretreatment, spatial smoothing filtering, image sharpening and other processes; the license plate image positioning methods are compared, and the Radon transform used to correct the license plate image; license plate character segmentation. The character contour method is used to segment the characters and the template matching method is used to license plate character recognition. The improvement of image processing is also proposed. It is proved that the current vehicle recognition system can meet the requirements of accurate license plate recognition, and the robustness and accuracy are improved compared with the general model.
