摘要:
 车牌定位是车牌自动识别系统中的一项关键技术,也是所有工作的前提和基础。目前虽然有一些车牌定位方法,但都存在识别精度不够准确的缺陷。为了提高车牌定位的精度,充分利用车牌自身的有用信息,在借鉴前人研究成果的基础上提出了一种基于小波变换和支持向量机的车牌定位方法。首先利用小波变换将图像中的竖直纹理特征提取出来,再利用数学形态学进行操作得到候选车牌区域,最后利用车牌的综合特征和支持向量机实现车牌的精确定位。实验结果表明该方法在背景复杂的情况下具有很好的效果。
Abstract:
 The vehicle license plate location is one of the key technologies in the license plate intelligent recognition system and it is nec-essary for the other work. Though there has some license plate location methods,the deficiency is low recognition accuracy. To improve the location level,a new method is proposed based on wavelet transform and support vector machines on the basis of previous research, fully applying the useful information of license plate. It has made use of wavelet transform to extract the vertical texture features. And then obtain the candidate plate location areas by using the mathematical morphology. Finally, the precise license plate location is located through support vector machine based on the license plate comprehensive feature. Experimental results indicate the algorithm is efficient and effective.
