基于Android 平台智能手机的车牌快速识别系统

为提高交警处理突发事件及日常巡查工作的效率，提出了一种基于Android 平台和4G 网络传输的车牌快速识别系统方法。该方法利用4G 网络将移动端拍摄的图片传输到远程服务器，识别车牌号。利用车牌号在违章信息库中查询，并将查询结果实时回传到手机客户端。智能手机作为移动端，利用JAVA 对UI( User Interface) 界面进行布局，实现拍照、显示、信息录入等功能。实验结果表明，该APP 界面简洁，操作方便，系统功能齐全，能有效提升交警处理突发事件及日常巡查工作效率，从而缓解执法过程带来的交通拥堵问题。

Rapid Identification System for License Plate Based on Android Platform Smartphone

In order to solve the problem of traffic police dealing with emergencies and day-to-day inspections，a rapid identification of vehicle license plates based on Android platform and 4G network transmission is proposed．The method uses a 4G network to transmit pictures taken by a mobile terminal to a remote server to identify the license plate number． Use the license plate number to query the violation information database，and return the query result to the mobile client in real time． As a mobile terminal，a smartphone uses JAVA to layout a UI( User Interface) interface and implement functions such as photographing，display，and information input． With a simple interface，easy operation，and complete system functions，the APP can effectively improve the efficiency of the traffic police in dealing with emergencies and daily inspections，alleviating the problem of traffic congestion caused by law enforcement．
