Study on the identification system of car license plate based on imbedded computer system

The automatic identification system of car license plate is a kind of computer system which can extract the character information of a car license plate from a car image in terms of computer vision technique, image processing technique and pattern recognition technique, etc. It is one of the important parts of realizing traffic management intelligentization. An automatic identification system of car license plate based on imbedded computer system applicable for intelligent traffic field is studied in this paper. Some relative algorithms are proposed to realize the partition of the car license plate characters. This paper also illustrates the hardware and software of the imbedded computer system in detail used to car license plate. As one of the important parts of the intelligent traffic system, the car license plate identification technique has wide future application and theoretical significance with the combination to the developing imbedded computer system.
