优秀毕业论文 精品参考文献资料 RESEARCH RESEARCH AND EMPOLDER CAR CONTROL SYSTERM BASED ON LICENSE PLATE RECOGNITION Abstract In this dissertation，computer vision was be used硒a important measure，and at the same time，adopting other measures include digital image processing， artificial neural network to research the technology of license plate actualize recogise．And introduce the characteristic of car manage systerm which was applicated in campus and base On plate recogise technology．finally empolder a car manage systerm aim at specifically field． The thesis is mainly concerned about： First collect Car license plate image，and then process the primitive image through stretching the gray and median filtering．The method of Ostu is to get the threshold value．Orientating the plate through it texture characters after that unitary the image，big space and image uprightness projection are used to devide the characters。Using statistic method to distill the character of the plate and recognise them by BP artificial neural network．．Finally empolder date base and Car manage systerm for certain condition．through ADO technique to connect them，Let Car management function come true． In this dissertation it use programme of Matlab and VB to achieve the arithmetics which is based Oll the theorys， and then compose the software flat roof of recognize and management．This systerm call Orientating devide recognize the image well base on test date．this research provide a new application field for license plate actualize rgcogise systerm．It also has important significance for improving the application of computer vision technology,artificial neural network and expert system in real field． Keywords：machine vision：digital image processing；artificial neural network； license location：character recognition H 广西大学学位论文原创性声明和学位论文使用授权说明 广西大学学位论文原创性声明和学位论文使用授权说明 学位论文原创性声明 本人声明：所呈交的学位论文是在导师指导下完成的，研究工作所取得的成果和相 关知识产权属广西大学所有。除已注明部分外，论文中不包含其他人已经发表过的研究 成果，也不包含本人为获得其它学位而使用过的内容。对本文的研究工作提供过重要帮 助的个人和集体，均已在论文中明确说明并致谢。 论文作者签名：
