一個典型的汽車車牌自動識別系統，其基本處理流程如下圖所示：

車牌定位：

從整個圖像中準確地檢測出車牌區域，是車牌識別過程的一個重要步驟，如果定位失敗或定位不完整，會直接導致最終識別失敗。車牌定位方法一般會依據紋理特征、顏色特征和形狀特征等信息，采用投影分析、連通域分析、機器學習等算法檢測車牌。投影分析方法根據車牌字符與背景交替出現的次數相比于其他情況要多這個特征，通過圖像在水平和垂直方向的投影分析來定位車牌；連通域分析根據車牌中的每個字符都是一個連通域且這些連通域的結構和顏色都一致的特征，通過檢測并合并這些連通域來定位車牌。基于邊緣特征檢測：利用函數edge()實現邊緣檢測；機器學習的思路是，先使用從很多個車牌樣本中提取出來的特征把一個弱分類器訓練成一個強分類器，再使用這個強分類器對圖像進行掃描檢測從而定位到車牌。

車牌矯正：

? ? ? ?由于受拍攝角度、鏡頭等因素的影響，圖像中的車牌存在水平傾斜、垂直傾斜或梯形畸變等變形，這給后續的識別處理帶來了困難。如果在定位到車牌后先進行車牌校正處理，這樣做有利于去除車牌邊框等噪聲，更有利于字符識別。目前常用校正方法有：Hough變換法，通過檢測車牌上下左右邊框直線來計算傾斜角度、旋轉投影法、最近鄰聚類法等。

字符分割：

? ? ? ?對分割后的字符的灰度圖像進行歸一化處理，特征提取，然后經過機器學習或與字符數據庫模板進行匹配，最后選取匹配度最高的結果作為識別結果。目前比較流行的字符識別算法有：模板匹配法、人工神經網絡法等。模板匹配法的優點是識別速度快、方法簡單，缺點是對斷裂、污損等情況的處理有一些困難；人工神經網絡法學習能力強、適應性強、分類能力強但比較耗時。

字符識別：

模板匹配法：車牌字符識別是字符識別的重要組成部分。車牌字符識別的最終目的就是將圖像中的車牌字符轉化成文本字符，車牌字符的識別屬于印刷體識別范疇。字符識別的基本思想是匹配判別,抽取待識別字符特征按照字符識別的原理和預先存儲在計算機中的標準字符模式表達形式的集合逐一進行匹配，找出最接近輸入字符模式的表達形式，該表達形式對應的字就是識別結果。
