With the development of vehicles and the increasing number of cars in modern society, people pay more and more attention to the vehicle license plate recognition system. Vehicle license plate recognition is divided into three parts: license positioning, character segmentation and character recognition. This paper proposes a new way of vehicle license plate recognition. In license positioning, the license positioning method is based on median filtering double edge detection, in character segmentation, it adopts a combinative method of locating the original level and improved vertical projection segmentation algorithm, in character recognition, the recognition method is based on classification template matching of font characteristics. The proposed license recognition method focuses on the timeliness of recognition process. Its smaller calculation largely reduces the time of license recognition, with high accuracy and precision rate at the same time.
