【摘要】：隨著經濟的高速發(fā)展以及人民生活水平的提高,我國汽車保有量不斷增加,汽車已然成為人們生活中不可缺少的出行工具。汽車數量的增加導致道路擁堵現象嚴重,亂停車等違章現象頻繁發(fā)生。針對車輛堵塞、違章停車現象,以及交警執(zhí)法過程的不便,設計一套基于Android的違章車輛管理系統(tǒng),該系統(tǒng)可以方便交通管理部門進行違章車輛管理,并提高交警的執(zhí)勤效率。本文以車牌識別算法為基礎,結合計算機視覺技術和圖像處理技術,設計了一套基于Android的違章車輛管理系統(tǒng)。該系統(tǒng)使用Android手機拍攝違章車輛圖像,利用車牌識別算法對拍攝圖像進行車牌識別,自動獲取違章車輛車牌號,記錄車輛的違章信息；通過TCP通信實現手機端與服務器的連接,將違章信息上傳至服務器,通過違章車輛管理系統(tǒng)實現違章車輛的查詢和管理。本文的研究內容主要包括車牌識別算法的研究與改進、Android手機客戶端車牌識別程序設計以及服務器上違章車輛管理系統(tǒng)設計三部分：1.車牌識別算法的研究與改進。首先對車輛圖像進行預處理操作,經過灰度化處理、二值化處理、邊緣檢測以及形態(tài)學操作,得到預處理后圖像。然后進行基于紋理特征與垂直投影相結合的車牌定位,基于垂直投影技術的字符分割,基于模板匹配的字符識別,最終得到車輛的車牌號信息。該算法具有較高的識別率和較快的識別速度,可以用于實際的車牌識別系統(tǒng)中。2.違章車輛管理系統(tǒng)Android手機客戶端的設計與實現。該部分利用Android平臺的JNI功能實現車牌識別算法的移植,在Android客戶端設計中實現違章車牌拍照、車牌識別、違章信息記錄功能。為了進一步提高工作效率,該軟件還具備車牌識別結果錯誤時的人工矯正功能。3.服務器上基于MFC的違章車輛管理系統(tǒng)的設計與實現。該部分首先設計了基于MFC的違章車輛管理系統(tǒng),具有用戶登錄與管理員登錄兩個功能,并且構建了違章車輛管理數據庫,該數據庫包含了車輛基本信息、車主基本信息、車輛違章信息等內容。通過TCP通信實現了Android手機端與服務器端的連接,將Android手機客戶端的違章信息發(fā)送到服務器。本文設計的基于Android違章車輛管理系統(tǒng),將車輛拍照、車牌識別與車輛的違章查詢處理融為一體,能夠較為準確的識別出車牌號信息,方便交警管理處罰違章車輛。作為違章車輛的車主也可以登錄違章管理系統(tǒng)查看自己的違章記錄。
[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.
