摘要
车辆牌照的自动识别是智能交通系统中一项很重要的技术。针对车牌识别的前期技术 ,即车牌定位、车牌图像的对比度判断和二值化、字符分割等技术进行了研究并提出了新的处理方法 ,实验结果表明提出的算法简洁、实时性好、处理正确率高 。
The automatic license plate (LP) recognition is a very important technology in intelligent transportation systems (ITS).The new methods of the early technique of LP recognition, including LP location, LP image contrast estimation, binarization, and characters segmentation are studied and proposed. Experiment results showed that the algorithm proposed by this paper possesses the advantages of concise form, real-time standard and high process rate, achieving practical target.
