像素连接车牌定位技术的研究
The Study on License Plate Location Technology by Pixel Connection

车牌定位作为车牌识别的先导部分,其准确性决定了车牌识别系统的可靠性.现有车牌定位技术对融合后的图像进行形态学操作时,存在结构元素大小不易控制,并且若车身有着与车牌同样的颜色,形态学膨胀容易造成两者相连接的问题.针对该问题,提出了像素连接的车牌定位方法,达到较好的车牌识别边缘检测效果.
License plate location is regaded as the guide part of the license plate recognition,its accuracy determines the license plate recognition system reliability.The existing license plate locating algorithm has the following two problems,which is the fusion image morphological operation,the size of structural elements control; and if the body has a license and the same color and morphological dilation is likely to cause both connected.In view of the above problems,the method of license plate location based on pixel connection has been proposed to achieve the better edge detection results of the license plate recognition system
