【正文】 put forward higher request to the traffic management and control. The traffic management system in intelligent, license plate recognition technology (License Plate Recognition, LPR) is an important technology of vehicle identification and monitoring, play a very important role in the city vehicle management. License plate recognition technology is widely used in road illegal vehicle monitoring, parking management, vehicle safety management. License plate recognition software system is divided into three parts: license plate location, character segmentation and character recognition. This paper makes research and discusses the algorithm of license plate location and character segmentation method, according to the characteristic of license plate of a vehicle license plate location and character segmentation of simple algorithm is proposed. License plate location part uses the method of mathematical morphology, is realized by the following steps: first use the radon function to skew detection and correction of the image, and mathematical morphology processing by gray and edge detection, then can be carried out, finally is the extraction of license plate region. Character segmentation is made using projection method, analysis of pixel vertical projection histogram, with each character trough, wave and plate custom standards to divide each character. Using image processing capabilities of the MATLAB, through the preparation process, statistical analysis of vehicle image, to achieve the functions of two parts. The key of this method is the selection of appropriate structure elements, the license plate image mathematical morphology open, close operation to remove the interference factors, eliminating the noise and useless information, simple and intuitive, less interference by the environment. Through the experiment, in this paper, license plate localization algorithm and character segmentation method can achieve good effect.
