【正文】 基于 MATLAB 車牌圖像識別的設(shè)計與實現(xiàn) 摘 要 車牌圖像識別系統(tǒng)是現(xiàn)代智能交通管理的重要組成部分之一。車牌識別系統(tǒng)使車輛管理更智能化，數(shù)字化，有效提升了交通管理的方便性和有效性。 車牌識別系統(tǒng)主要包括了圖像采集、圖像預(yù)處理、車牌定位、字符分割、字符識別等五大核心部分。本文主要介紹圖像預(yù)處理、車牌定位、字符分割三個模塊的實現(xiàn)方法。其中圖像預(yù)處理模塊是將圖像灰度化和用 Roberts 算子進行邊緣檢測。車牌定位和分割采用的是利用數(shù)學(xué)形態(tài)法來確定車牌位置，再利用車牌彩色信息的彩色分割法來完成車牌部位分割。字符的分割 采用的方法是以二值化后的車牌部分進行垂直投影，然后在對垂直投影進行掃描，從而完成字符的分割。最后使用 MATLAB 軟件環(huán)境進行字符分割的仿真實驗，結(jié)果表明該方法具有良好的性能。 關(guān)鍵詞： 圖像處理，車牌定位，字符分割 The Design and Implementation of License Plate Image Recognition Based on MATLAB ABSTRACT License plate image recognition is an 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， Reuse license plate color segmentation method of color information to 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, thus pleting the character segmentation. This article is described for the core part and use the MATLAB software environment, the simulation experiments for character segmentation. Key words: plate recognition, location, character segmentation 目 錄 摘要 I ABSTRACTII 1 緒論 1 車牌圖像識別研究的背景 1 研究車牌圖像識別的目的和意義 2 車牌號識別技術(shù)研究現(xiàn)狀和趨勢 3 國內(nèi)外車牌圖像識 別研究現(xiàn)狀 3 我國車牌特點 3 車牌圖像識別技術(shù)的應(yīng)用前景 4 車牌圖像識別技術(shù)的發(fā)展趨勢 5 車牌圖像識別研究內(nèi)容 5 2 車牌識別系統(tǒng)設(shè)計原理概述 7 車牌在圖像中的位置提取 7 字符分割 8 字符識別 8 3 車牌識別系統(tǒng)程序設(shè)計 10 開發(fā)環(huán)境的選擇 10 設(shè)計方案 183
