PAGE 18 基于opencv的车牌识别系统设计与实现 Design and implementation of LPR system based on opencv 内容摘要 科技的进步以及人民自身的生活水平的不断提高，使得人们对于日常的出行需求变得不断增长。汽车作为最常见的交通工具已经越来越成为人们最初的选择。大量新的车辆在不断地投入到道路中使用，而以传统的人工方式对汽车车辆的管理也变得愈加困难。因此，使用计算机来代替人来处理相对繁重的工作是必要的。一个良好的交通管理系统是实现道路管理的基础。 想要对于汽车车辆进行管理，最有效的识别特征之一便是汽车的车牌，作为目前最常见的使用技术，车牌识别广泛应用在交叉路段、停车场、收费站等各种场合的监控与管理之中。所以需要相应的技术来完成以上的需求。本文以python为使用语言，OpenCV为主要工具，通过输入带有汽车车牌的图像，根据车牌所特有的一些特征，垂直投影法、SVM的方法来完成对于汽车车辆的车牌定位、车牌的字符分割以及字符识别功能。最终将所识别到的车牌字符输出显示出来。 关键词：OpenCV；投影法；SVM；车牌识别 Abstract The advancement of science and technology and the continuous improvement of peoples own living standards have made peoples daily travel needs continue to grow. As the most common mode of transportation, cars have become the initial choice of people. A large number of new vehicles are constantly being put into use on the road, and the management of automobile vehicles by traditional manual methods has become increasingly difficult. Therefore, it is necessary to use a computer instead of a person to handle relatively heavy work. A good traffic management system is the foundation for road management. One of the most effective identification features for the management of automobile vehicles is the license plate of the car. As the most commonly used technology at present, license plate recognition is widely used in monitoring and management of various occasions such as intersections, parking lots, toll stations In. Therefore, corresponding technology is needed to complete the above requirements. This article uses python as the language and OpenCV as the main tool. By inputting an image with a car license plate, according to some characteristics unique to the license plate, vertical projection and SVM are used to complete the license plate positioning, character segmentation and characters of the car license plate. Recognition function. Finally, the recognized license plate characters are di
