浙江万里学院 本科毕业设计(论文) (2013届) 论文题目 基于Matlab的车牌识别系统的设计与实现(英文) Design and Implementation of Matlab-based license plate recognition system 所在学院 电子信息学院 专业班级 xxxxxx 学生姓名 xxxx 学号 xxxxxx 指导教师 xxxx 职称 副教授 完成日期 年 月 日 摘 要 汽车车牌的识别系统是现代化的智能交通管理领域的重要组成部分之一。车牌识别系统能使车辆管理更加智能化和数字化，可以有效地提升交通管理的方便性与有效性。车牌识别系统中主要包括了五大核心部分，分别是图像采集、图像预处理、车牌定位、字符分割、字符识别等。而本文主要介绍的是图像预处理、车牌定位、字符分割这三个模块的实现方法。本文的图像预处理模块的步骤是将图像灰度化和用Roberts算子进行边缘检测。分割采用和车牌定位是利用的数学形态法来确定车牌的位置，然后利用车牌彩色信息彩色的分割法来完成车牌部位的分割。字符的分割采用的是以二值化后的车牌部分进行垂直投影的方法，之后再对垂直投影进行扫描，来完成字符的分割。本文针对其的核心部分是进行阐述并使用MATLAB软件环境下来进行字符分割的仿真实验。 关键词：MATLAB；图像预处理；车牌定位；字符分割 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 modules. This 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 to complete 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, thus completing the character segmentation. This article is described for the core part and use the MATLAB software environment, the simulation experiments for character segmentation.
