摘要
车牌定位是自动识别的关键步骤,而在整个车牌定位过程中,边缘检测是其中的一项重要环节和关键技术.文中在分析了目前常用的边缘检测方法后,给出了一种基于Sobel算子的改进边缘检测方法.实验结果证明具有较好的检测效果.
Localization of the car plate is a key step, and edge-detection is an important point in the locating process After analyzing popular methods used in edge-detection, a method for localization of the car plate using edge-detection based on improved Sobel operator is provided in this paper. The experiments result shows a good detecting effect.
