摘要
为快速识别身份证号码,以计算机视觉系统为技术手段,以第二代居民身份证为研究对象,从身份证号码图像中提取号码数字0—9的空间分布特征和结构特征,采用相似系数最大和结构特征一致准则,应用MATLAB软件编程实现了身份证号码的快速识别.运用图像处理和模式识别技术,实现了身份证号码图像的预处理、图像分割、号码图像的修正、号码体的定位、号码体的识别等算法,建立了基于摄像头的身份证号码识别系统.系统的识别速度和准确率可满足实际需要.
Taking the computer vision system as the technical means as well as the second generation ID as the research object,the fast recognition of ID number has been realized by extracting characteristics of spatial distribution and structure of number 0-9 from the digital ID number image,using the criteria of maximal similarity coefficient and consistent structural characteristics,and programming by the MATLAB software.Many algorithms have been realized such as ID number image pretreatment,image segmentation,image correction,number orientation and identification using image processing and pattern recognition technology,and ID number identification system has been established on the basis of cameras,whose recognition speed and accuracy can meet the practical demands.
