基于C++的手背脉络特征认证考勤技术研究

Based on the study of the C ++ on certified checking attendance technology of the dorsal hand venation characteristic

将功能强大的C++语言与数据库技术结合起来,充分发挥其强大的技术优势,应用于手背脉络特征认证考勤技术研究.研究通过静脉识别仪取得个人手背静脉分布图,运用专门的比对算法从静脉分布图像中获取特征值.研究过程中使用红外线CCD摄像头来获得手背的静脉数字图像,并将该图像的特征值提取后存储于计算机系统中.进行图像比对时,通过实时采集静脉图像,加以滤波、图像二值化、图像细化等先进手段提取图像特征值,并与存储在计算机系统中的静脉图像的特征值进行比对,然后运用专用的数字图像匹配算法进行特征匹配来鉴定个人身份.

This paper is going to combine the powerful C ＋＋language with database technology in order to completely play its powerful technology advantages and to be applied to the study on certified checking on work attendance technology of the dorsal hand venation characteristic.This study can get the vein distribution diagram of the dorsal hand by means of vein identification instrument, extracts the characteristic values from the vein distribution diagram according to dedicated alignment algorithm.Obtain the image of the dorsal hand vein by means of infrared CCD camera, save the digital image of the vein in the computer system, and make characteristic values saved.We adopt vein images in real time, extract the characteristic values, and apply advanced filtering, the value of the two images, refinement methods to extract features from digital images when the venous comparison.Then compare them with the characteristic values saved in the computer and apply complicated matching algorithm to match the vein features, therefore we can conduct identity identification and confirm her or his identity.
