A vision - based license plate identification system has to be robust, since the plate may be inclined or distorted, the characters may be blurred and the strokes become disconnected. the algorithms also have to be adaptable since the light condition and image capture position could vary. the license plate identification system has to implement license plate region identification, character extraction and character recognition. we use edge features and shape features to locate the plate region, in this process image enhance and mathematical morphology are used
本論文的研究重點主要包括牌照的定位、牌照中字元的分割和字元識別三部分，通過對圖像處理和分析技術的綜合運用以及對問題本身特點的詳細考察，最終實現了基於邊緣特徵和形態學分析的牌照定位演算法，在圖像預處理方面採用灰度變換、同態增晰和平滑演算法對圖像進行處理，提高了牌照圖像的質量。
