License Plate Detection System Based On NIOSII

this paper presents the implementation of a real-time FPGA license plate recognition system, and we achieve the detect license detection plate hardware base on SOPC, we got good performance of real-time detection .In this paper, the license plate detection we achieve by using discrete wavelet transform(DWT) and morphology. Furthermore the object Connect Component Labeling method to segment each independent block and identify the images license plate location coordinates. Before we get the characters of each registration coordinates, we should segment each region of the characters from the plate. The character image will be send to character recognition software (OCR). After that, the license plate characters identification will be finish.Using above method, we can achieve this purpose on Terasic company's DE2-70 FPGA development kit, which compose of Altera NIOSII soft core embedded processor and SOPC platform development environment. .After the system finished the plate detection and cutting out characters.
