But License plate recognition system, intelligent transportation systems research and development is constrained, modern important factor in the development of modern traffic drawn greater attention.  The topic of the vehicle license through analysis of a series of characteristic information obtained, including the automotive image pre-processing, license plate location, license plate image segmentation and character recognition, etc, designed and implemented a prototype system license plate recognition, and the topic through the analysis of a series of the automotive image pre-processing , license plate location will obtain lots of conclusions , thus start the analysis of the topic，including Gray processing method of color image，Image enhancement，Edge detection，License plate location steps and so on . Key words: image pre-processing;license plate recognition; character recognition 目 录 一、绪论 1 1．1课题研究的阐述 1 1. 2 课题研究的目的及基本思路 2 1. 2．1 课题研究的目的 2 1. 2. 2 课题研究的基本思路 2 1.3 课题研究的意义 2 二、车牌识别系统分析及要求 3 2.1车牌识别系统分析 3 2．1．1 车牌识别系统的需求分析 3 2. 1. 2 我国车牌照识别的特殊性 3 2．1．3国内外研究的历史、
