摘　　要：随着智能化交通管理系统的飞速发展,对车牌的定位和识别提出了更高的要求,因此提出了一种结合边缘检测和数学形态学的车牌定位算法。采用Sobel算子进行边缘检测,经数学形态学处理得到连通的车牌候选区域,然后对其进行分析,实现车牌区域定位。实验结果表明,该方法能准确实现车牌定位,性能良好。With the rapid development of intelligent traffic management system , high requirements for the location and recognition of vehicle license plate are put forward. A license plate positioning algorithm combined with edge detection and mathematical morphology is presented in this paper. The Sobel operator is used for edge detection,the connected candidate re-gions are obtained and analysed by mathematical morphology,thus the zone of a license plate is positioned. The experimental re-sults show that the method can accurately realize the license plate location,and its performance is good.
