摘 要
车辆牌照自动识别系统是近几年发展起来的基于图像和字符识别术的智能化交通管理系统,是目前国内外模式识别应用研究领域的一个热点。本文对系统中图像预处理、字符分割和字符识别等环节涉及的新算法、新设计做了一个比较详细的论述。
本文在图像预处理中重点讨论了灰度图像二值化的多种算法和基于数学形态学的图像去除噪声的方法。基于数学形态学的图像去除噪声是通过对图像的开、闭操作有选择的去噪。可以去除直径小于字符笔划半径的孤立噪声点。
本文还详细地介绍了基于字符形态划分的字符识别方法。基于字符形态划分的字符识别方法是在对数字字符结构进行充分分析的基础上,对基元检测,归纳字符形态特征,得到的快速字符识别方法。

Abstract
The vehicles license plate automatic diagnosis system is develops inrecent years based on the image and the character recognition technology intellectualization traffic control system, is a present domestic and foreign patterns recognition applied research domain hotspot. This article to the system in the image pretreatment, the characteristic with drew the new algorithm, the technique design which with link and so on character recognition involved has made a quite detailed elaboration.
This article also with emphasis discussed based on has connected the value the image to go to chirp the method and based on the character shape and the structure direction characteristic quantity extraction process. Goes based on the connected domain image chirp is through carries on to the image corrosion and the inflation has the choice to go chirp. May remove the diameter to be smaller than the character pen to delimit the radius the isolated noise spot.
This article also detailed introduction based on character shape character recognition method. Is in carries on the sufficient analysis construction based on the character shape character recognition method to the alphanumeric character structure in the foundation, the induction character shape characteristic, obtains fast character recognition method.
