摘　　要：以快速准确识别汽车牌照号码为目的,在充分利用牌照纹理特征和投影特征的基础上,运用灰度变换、边缘检测、形态学处理、Hough变换、二值化处理等多种图像处理方法,分牌照定位、字符分割、字符识别三步实现汽车牌照的识别,在处理过程中考虑并解决了现实拍摄的图像中可能存在的噪声污染、牌照倾斜、牌照颜色多样化、光照不均等不利条件;整个识别过程在VC++环境下编程实现,经对多幅图片的处理实验表明,该系统运算速度快,识别率高。Aiming at fleetly and correctly recognizing the number of the License Plate,this paper makes a full use of the texture and the projection characteristics of the License Plate and expounds the whole License Plate Recognition process in detail,including the process of li-cense plate location,character segmentation and character recognition.Many image processing methods are involved,such as monochrome image processing,edge detection,pattern processing,Hough processing and binarization.C ＋ ＋ language is used to realize the whole process,and test shows that this method is effectual and can correctly recognize the license plate characters.
