车辆牌照识别系统是一个基于数字图像处理和字符识别的智能化交通管理系统，该先系统通过视频采集接口采集摄像头摄入包含车牌的视频图像，再对动态采集到的图像进行处理以克服图像干扰，改善识别效果，接着在动态采集到的图像中自动找到车牌的位置也就是边缘检测，并分割出单个字符的矩形区域, 然后对车牌进行二值化,最后把规整好的字符输入字符识别系统进行识别。如果车辆在通过设有视频采集摄像头的路口是出现超速、超载、闯红灯等违章现象该系统就可以通过拍摄到的违章车辆牌照进行处理并向工作人员发出报警。该系统适合于城市交通管理、高速路汽车超载、超速监控、公路计费、停车场管理、被盗车辆的侦破等应用。因此基于计算机图像处理和字符识别技术的车牌自动识别技术，有着极其广阔的推广应用前景。
Vehicle license plate recognition system is an intelligent traffic management system based on digital image processing and character recognition. Firstly, the system collects video images including license plate from camera through video acquisition interface, and then processes the images collected dynamically to overcome image interference and improve recognition effect, and then automatically finds the location of license plate in the images collected dynamically It is the edge detection, and the rectangular area of a single character is segmented, then the license plate is binarized, and finally the regular characters are input into the character recognition system for recognition. If there are violations such as overspeed, overload and red light running when the vehicle passes the intersection with video capture camera, the system can deal with them through the license plate of the vehicle and send an alarm to the staff. The system is suitable for urban traffic management, highway vehicle overload, overspeed monitoring, highway billing, parking lot management, stolen vehicles detection and other applications. Therefore, the license plate automatic recognition technology based on computer image processing and character recognition technology has a very broad application prospect.
