Abstract: Vehicle license plate recognition system is the hardcore of the intelligent traffic system. Through the research of four key links of the license plate location, image pre-processing, character segmentation and character recognition, the paper has designed an intact license plate recognition system and has implemented the simulation in the environment of MATLAB. The license plate location, which is based on colour character and vein character, has realized the thick location of the blue bottom and white word license plate. The image pre-processing, which is included gray processing, binary processing and the license plate slant correction to the horizontal line, is adopted by the related operation of mathematical morphology and Radon transformation. Character segmentation is based on the improved horizontal projection. Aiming at the characteristic of China-style license plates, the character recognition is proposed to use four kinds of different classification devi!
ces by using the improved BP neural network. This system is effective for solving the problems which are Chinese character unconnected, cement of the character, illumination variance and interference of the noise and space mark.
Keywords: Artificial neural network, Character segmentation, Image processing, License plate recognition, Mathematical morphology, Radon transformation.
