Paper Abstract

A Number Plate Recognition System with a special linear CCD imager is presented in this paper. The system is fixed on the top of the roadway to obtain the images of the moving vehicles. With the linear image sequence, we have detected the position of Number Plate with corresponding algorithm and output 2-dimension sub-image of Number Plate by standard video for Optical Character Recognition (OCR). The 2-dimension image combined with the linear image sequence has higher transverse resolution (2048pixels) than that of the normal standard video (768pixels). Moreover, even images and accurate location of the characters can be gained with the linear CCD imager. The system is based on FPGA technology, and it can detect the vehicles Real-timely and recognize Number plate.
