一种基于颜色特征的车牌定位方法
首发时间:2010-01-20
摘要:车牌的有效定位是车牌识别过程中非常重要且基础的一个步骤。针对车牌具有的国家规定的颜色特征,利用HSV图像的特性对车牌颜色进行有效的分割。颜色分割后的图像具有的不同阶的灰度值,有选择的进行二值化处理,从而能够快速地实现车牌的定位。对车牌的定位算法用matlab进行实现,通过大量的图像试验可以得出,基于颜色特征的车牌定位快速而有效。

A method of vehicle license plate location based on color feature
Abstract:Efficient license plate location is an important and basic step. Aim at the color feature National requirements for the license plate,using the characteristics of HSV image splits the color of the plate effectively. The image after color segmentation has the gray value at different levels, have a choice to binaryzation processing, then, can realize license plate location quickly. The algorithm of license plate location is achieved by matlab, concludes by A large number of experiments, The license plate location based on color feature is rapid and effective.
