【摘要】：随着经济的高速发展以及人民生活水平的提高,我国汽车保有量不断增加,汽车已然成为人们生活中不可缺少的出行工具。汽车数量的增加导致道路拥堵现象严重,乱停车等违章现象频繁发生。针对车辆堵塞、违章停车现象,以及交警执法过程的不便,设计一套基于Android的违章车辆管理系统,该系统可以方便交通管理部门进行违章车辆管理,并提高交警的执勤效率。本文以车牌识别算法为基础,结合计算机视觉技术和图像处理技术,设计了一套基于Android的违章车辆管理系统。该系统使用Android手机拍摄违章车辆图像,利用车牌识别算法对拍摄图像进行车牌识别,自动获取违章车辆车牌号,记录车辆的违章信息；通过TCP通信实现手机端与服务器的连接,将违章信息上传至服务器,通过违章车辆管理系统实现违章车辆的查询和管理。本文的研究内容主要包括车牌识别算法的研究与改进、Android手机客户端车牌识别程序设计以及服务器上违章车辆管理系统设计三部分：1.车牌识别算法的研究与改进。首先对车辆图像进行预处理操作,经过灰度化处理、二值化处理、边缘检测以及形态学操作,得到预处理后图像。然后进行基于纹理特征与垂直投影相结合的车牌定位,基于垂直投影技术的字符分割,基于模板匹配的字符识别,最终得到车辆的车牌号信息。该算法具有较高的识别率和较快的识别速度,可以用于实际的车牌识别系统中。2.违章车辆管理系统Android手机客户端的设计与实现。该部分利用Android平台的JNI功能实现车牌识别算法的移植,在Android客户端设计中实现违章车牌拍照、车牌识别、违章信息记录功能。为了进一步提高工作效率,该软件还具备车牌识别结果错误时的人工矫正功能。3.服务器上基于MFC的违章车辆管理系统的设计与实现。该部分首先设计了基于MFC的违章车辆管理系统,具有用户登录与管理员登录两个功能,并且构建了违章车辆管理数据库,该数据库包含了车辆基本信息、车主基本信息、车辆违章信息等内容。通过TCP通信实现了Android手机端与服务器端的连接,将Android手机客户端的违章信息发送到服务器。本文设计的基于Android违章车辆管理系统,将车辆拍照、车牌识别与车辆的违章查询处理融为一体,能够较为准确的识别出车牌号信息,方便交警管理处罚违章车辆。作为违章车辆的车主也可以登录违章管理系统查看自己的违章记录。
[Abstract]:With the rapid development of economy and the improvement of people's living standard, the number of cars in our country is increasing. Automobile has become an indispensable means of travel in people's lives. The increase in the number of cars leads to serious road congestion, random parking and other illegal phenomena occur frequently. In view of vehicle congestion, illegal parking phenomenon. As well as the inconvenience of traffic police law enforcement process, the design of a vehicle management system based on Android, this system can facilitate traffic management departments to manage illegal vehicles. And improve the efficiency of traffic police on duty. This paper based on license plate recognition algorithm, combined with computer vision technology and image processing technology. A vehicle violation management system based on Android is designed. The system uses Android mobile phone to capture the illegal vehicle image and uses the license plate recognition algorithm to recognize the license plate of the captured image. Automatically obtain the license plate number of the illegal vehicle and record the violation information of the vehicle; The connection between the mobile phone and the server is realized through TCP communication, and the violation information is uploaded to the server. Through the illegal vehicle management system to achieve the query and management of illegal vehicles. The research content of this paper mainly includes the research and improvement of license plate recognition algorithm. Android mobile phone client license plate recognition program design and server vehicle management system design three parts: 1. License plate recognition algorithm research and improvement. First of all the vehicle image preprocessing operation. After gray processing, binary processing, edge detection and morphological operation, the pre-processed image is obtained, and then the license plate location based on texture feature and vertical projection is carried out. The character segmentation based on vertical projection technology and the character recognition based on template matching result in the vehicle license plate information. The algorithm has higher recognition rate and faster recognition speed. It can be used in the actual license plate recognition system .2. the design and implementation of the Android mobile phone client in the vehicle violation management system. This part uses the JNI function of the Android platform to realize the license plate recognition. The transplant of algorithms. In the design of Android client, the functions of license plate photo, license plate recognition, violation information record are realized in order to further improve working efficiency. The software also has the function of manual correction when the result of license plate recognition is wrong. 3.Design and implementation of the vehicle management system based on MFC on the server. Firstly, this part designs the illegal vehicle management based on MFC. The system. With user login and administrator login two functions, and build a violation of the vehicle management database, the database contains the basic information of the vehicle, the owner of the basic information. Through the TCP communication, the connection between the Android mobile phone and the server is realized. The Android mobile phone client violation information sent to the server. This paper based on the Android illegal vehicle management system, will take pictures of the vehicle. License plate recognition and vehicle violation query processing are integrated, which can identify the license plate information more accurately. It is convenient for traffic police to manage and punish illegal vehicles. Owners of illegal vehicles can also log on to the system to check their own records of violations.
