中文摘要：

为解决违章车和套牌车的身份认证问题,设计了基于图像的车辆品牌识别方案。基于车标图像识别车辆品牌存在定位困难的缺点,利用车脸格栅作为识别对象则可以提高车辆品牌的识别准确率。提出了一种车辆格栅定位方法,包括形态学处理、二值化、连通域检测和梯度投影定位等操作,实验结果表明了该方案的有效性。

英文摘要：

In order to get illegal car and fake-licensed car identification, a scheme on vehicle brand recognition based on digital image is designed. It is difficult to recognize brand based on the location of image of car logo however high the recognition rate is. A locating car face grid method, including morphology operation, binaryzation, connected area detection and gradient projection, is presented. The experimental results show that the method is efficient.
