基于单片机的车牌识别设计

AbstractWith the development speed of the whole world,the rapidimprovement of science and technology and the continuous developmentof people's life,a large number of motor vehicles from all over the worldare more and more appearing in people's vision.The appearance of motorvehicles has brought convenience to the traffic of the whole world,but atthe same time,the congestion of roads and the pollution of cities are alsoincreasing.In China and even in other countries around the world,it isoften There are crowding,car accidents and all kinds of illegal activities.Therefore,vehicle identification is very important for us.It caneffectively catch up with the hit and run vehicles,run the red light andoverspeed driving.This design is a license plate recognition system basedon STM32 single-chip microcomputer.We can recognize the license platenumber of every illegal car by the system.In the whole design,TFT LCDis used to display the current information.Ov7670 camera module is usedfor image acquisition.Finally,some hardware peripherals,drivers andapplications are added to the core processor to detect the license platenumber of the current car in time.Keywords:STM32 single chip microcomputer LCDcameramodule
