基于FPGA的车牌识别系统设计

FPGA- Based License Plate Recognition System

在中小城市交通高峰时间段,车辆违停往往会导致交通拥堵以及严重的交通事故,文中提出一种基于FPGA的车牌识别系统辅助交警的判断。该系统由摄像头采集模块、LCD显示模块两大模块组成,通过C语言描述车牌识别算法。在Nios II平台上,通过JATG下载验证,系统能间断性工作,实现对道路上车辆的图像采集、处理及显示等功能。该系统具有可靠性高、运行速度快、成本低廉,便于安装等特点,对降低交通拥堵减少交通事故发生率具有重要意义。

In the small and medium- sized city,traffic peak time period,the vehicle illegal stop often can cause the traffic congestion and the serious traffic accident,we proposed FPGA- based license plate recognition system auxiliary police comrades judgment. The system consists of two modules,which are camera acquisition module and LCD display module,license plate recognition algorithm described by C language. Downloading the validation by JATG,the system can work intermittent,realization of the road vehicle image acquisition,processing and display functions on the Nios Ⅱ platform,. The system has high reliability,fast,low cost,easy to install,etc.,to reduce traffic congestion reduce accident rates it is important.
