[Abstract]:With the rapid development of China's economy, the number of motor vehicles is increasing, and the corresponding strengthening of traffic management has also been raised to the status of high attention to this phenomenon, intelligent transportation systems have emerged one after another. As an important part of its, license plate recognition has become the focus of research. Nowadays, network technology and multimedia technology have been widely covered, and digital images have been widely used in various fields of production and life. Digital image processing technology has become one of the most rapidly developing subjects in information science and technology in recent decades. In this paper, the median filtering algorithm of license plate recognition digital image is studied. In order to obtain more information from the license plate digital image and improve the image quality, it can not meet the needs of real-time and efficient image processing only by software. At the same time, with the rapid development of microelectronics technology, It also makes digital image processing based on various hardware platforms more advantageous for license plate recognition. The characteristic of digital image processing is that the large amount of data processing is very time-consuming. In this paper, the hardware description language is used to realize the image processing algorithm based on FPGA. Firstly, the related knowledge and algorithm of digital image processing are introduced, and the basic principles of histogram equalization convolution filtering edge detection are described. Then, the principle of FPGA and the development platform of Quartus are introduced in detail. Finally, the fast median filter algorithm is selected and a three-point comparator is designed with FPGA. The logic design and basic algorithm of median filter on FPGA are realized by using verilog HDL hardware description language. In this paper, the principle description program design and timing simulation of digital image median filter algorithm based on FPGA are made, and the research of digital image processing using hardware description language is realized. It plays a positive role in the research and implementation of the digital image processing system of license plate recognition based on FPGA.
