摘要
随着我国高等教育的发展,迫切需要实验室全天候开放,但是引出了管理上的一些问题,特别是学生多、流动性大,值班与指导教师管理和考勤困难;另外,由于学生出入频繁、轮次间交接不明确,导致设备仪器损坏增多。因此,需要开发一种身份认证系统以满足开放实验室管理的需求。本文设计基于指纹检测识别技术的开放式实验室管理系统的构架,用一种基于细节点的指纹匹配算法实现自动指纹检测识别,该算法通过固定窗函数改为可变窗函数,从而更好地适应指纹图像非线性形变,阐述整个实验室系统软件实现流程。通过FVC指纹数据库实验和现场模拟实验,进行了技术评估测试和现场评估测试,验证了该系统的可行性。
As the rapid development of the higher education in China, it is very urgent to open the laboratories in full time. But it also cause some management problems, particularly in flow and large population. The staffs are hard to make the schedules clear enough to deal with cheek-in. It is an urgent demand to deploy an open laboratory management system which shouht be based on the identification. This paper designes an open laboratory management system hased on fingerprint measurement identification and use minutia fingerprint matching algorithm to realize automatic fingerprint detection identification, which makes the algorithm more robust to nonlinear deformation between two images by changing a stable window into an alterable one. Finally, it stduies the whole software implemenation process. It adoptes the FVC fingerprint database and live stimulation to make experiments on the automatic fingerprint identification algorithm and verified the availability of the system.
