文档介绍：ABSTRACT
Vehicle license plate recognition system is one important of the modern intelligent traffic management. License plate recognition system to make more intelligent vehicle management, digital, Effective traffic management to enhance the convenience and effectiveness. License plate recognition system includes image acquisition, image preprocessing, license plate localization, character segmentation, character recognition and other five core parts. In this paper, preprocessing, license plate localization, character segmentation method for the realization of three is the image preprocessing module and the use of the image grayscale Roberts edge detection operator steps. License plate location and segmentation using mathematical morphology method is used to determine the license plate location,Re-use license plate color segmentation method of color information plete the license plate area segmentation. Character segmentation approach is based on the license plate after the binary part of the vertical projection, Then scan in the vertical projection, pleting the character segmentation. This article is described for the core part and use the MATLAB software environment, the simulation experiments for character segmentation.
Keywords: MATLAB software, image preprocessing, license plate localization, character segmentation .
