摘要
隨著二十一世紀到來，經(jīng)濟快速發(fā)展和人們生活水平顯著提高，汽車逐漸成為家庭的主要交通工具。汽車的產(chǎn)量快速增多，車輛流動也變得越來越頻繁，因此給交通帶來了嚴重問題，如交通堵塞、交通事故等，智能交通系統(tǒng)(Intelligent Transportation System)的產(chǎn)生就是為了從根本上解決交通問題。在智能交通系統(tǒng)中車牌識別技術占有重要位置，車牌識別技術的推廣普及必將對加強道路管理、城市交通事故、違章停車、處理車輛被盜案件、保障社會穩(wěn)定等方面產(chǎn)生重大而深遠的影響。
該設計主要研究基于MATLAB軟件的汽車號牌設別系統(tǒng)設計，系統(tǒng)主要包括圖像采集、圖像預處理、車牌定位、字符分割、字符識別五大核心部分。系統(tǒng)的圖像預處理模塊是將圖像經(jīng)過圖像灰度化、圖像增強、邊緣提取、二值化等操作，轉(zhuǎn)換成便于車牌定位的二值化圖像；利用車牌的邊緣、形狀等特征，再結(jié)合Roberts 算子邊緣檢測、數(shù)字圖像、形態(tài)學等技術對車牌進行定位；字符的分割采用的方法是將二值化后的車牌部分進行尋找連續(xù)有文字的塊，若長度大于設定的閾值則切割，從而完成字符的分割；字符識別運用模板匹配算法完成。以上每個功能模塊用MATLAB軟件實現(xiàn)，最后識別出車牌，在研究設計的同時對其中出現(xiàn)的問題進行具體分析、處理，并尋求更優(yōu)的方法。
