中文摘要
汽车车牌随着整个世界的发展速度，科学技术的迅速提高以及人民生活的不断发展，大批量来自世界各地的机动车越来越出现在人们的视野当中，机动车的出现使得整个世界的交通带来了便利，但同时道路的拥挤，城市的污染也随之加剧，在中国乃至世界各国来说，常常出现拥挤，车祸以及各种各样的违法行为。因此，车辆的识别对于我们来说是非常重要的，可以有效地追中肇事逃逸的车辆，闯红灯以及超速驾驶等行为。本设计是一款基于STM32单片机的车牌识别系统，我们可以通过系统的识别，可以在远程追中每辆违法小车的车牌号码。在整个设计中，运用了
TFT液晶显示屏来显示当前信息，OV7670摄像头模块进行图像采集，最后，通过核心处理器上添加一些硬件外设，驱动程序和应用程序，来及时的检测出当前小车的车牌号码。

Abstract
With the development speed of the whole world, the rapid improvement of science and technology and the continuous development of people's life, a large number of motor vehicles from all over the world are more and more appearing in people's vision. The appearance of motor vehicles has brought convenience to the traffic of the whole world, but at the same time, the congestion of roads and the pollution of cities are also increasing. In China and even in other countries around the world, it is often There are crowding, car accidents and all kinds of illegal activities. Therefore, vehicle identification is very important for us. It can effectively catch up with the hit and run vehicles, run the red light and overspeed driving. This design is a license plate recognition system based on STM32 single-chip microcomputer. We can recognize the license plate number of every illegal car
by the system. In the whole design, TFT LCD is used to display the current information. Ov7670 camera module is used for image acquisition. Finally, some hardware peripherals, drivers and applications are added to the core processor to detect the license plate number of the current car in time.
