指纹识别技术在校园一卡通系统中的应用研究

介绍了指纹识别的原理和方法,针对常规指纹识别算法的指纹图像易受旋转和平移的影响、细节特征点提取步骤繁琐、比对速度较慢的现状,提出了一种基于纹线方向信息的自动指纹识别算法。研究了指纹识别技术在校园一卡通系统中的应用。该系统将一张射频卡集学生证（工作证）、借书证、准考证、消费卡、银行卡等功能于一体,实现真正意义的“一卡通”。

On the Application of Fingerprint Edentification Technology in the Campus Smart Card System

The paper will introduce the principium and technology of Fingerprint Recognition. the fingerprints images are received by normal algorithms of Fingerprint Recognition Because in the routine fingerprint identification algorithms the fingerprint images are easily affected by rotation and motion, the way of minutiae extraction is trivial and the matehing speed is slow, a new algorithms based on information of lines＇ direction is presented . So the paper tries to propose an automatic arithmetic of Fingerprint Recognition based on the information about the directions of fingerprints. The paper will research application of identifying fingerprints to Campus Card System, The system will realize all of functions of many cars, such as students＇ certification, employee＇s card, library card, consumption card. and bankcard, etc.
