基于人脸识别的校园教师人脸打卡设计和实现 电子信息工程专业VIP免费

I基于人脸识别的校园教师人脸打卡摘要随着信息技术的不断发展，员工的考勤管理成为企业、事业单位人事管理的重要内容，各种层出不穷的考勤系统也逐渐被应用到考勤管理中。而高校对于教师上课的考勤工作却处于一个相对空白的领域，传统的考勤方式往往会增加学校的管理成本，增加教师工作量，也会占用一定时间。基于此，本文的主要工作是设计一套针对高校教师的考勤系统，该系统可较方便、快捷地对高校教师进行上课考勤。本论文首先介绍了本专题研究的背景和意义、面部识别的基本原则以及检测个人和个人人脸识别的基本方法。第二部分是设计，涉及硬件平台也涉及软件算法。硬件平台用TMS320DM6437型DSP。设计开发了一些扩展电路，如模块化的电源系统、模块化的存储系统电路和模块化的IIC电路、模块化的人脸采集电路。而软件算法部分结合了OpenCV等工具，目前软件部分已经完成代码开发和出勤系统各个功能模块的实现，并对系统性能进行了试验、测试。测试结果表明，该文当中所设计的出勤系统在个人识别和出勤管理方面有很大的作用，对人们的签到、出勤有很大的影响，符合需求分析的相应的要求，在使用方面有一定的价值。【关键词】人脸识别；教师；考勤打卡IIFacerecognitionbasedoncampusteachersfacepunchAbstractWiththecontinuousdevelopmentofinformationtechnology,employeeattendancemanagementhasbecomeanimportantpartofthepersonnelmanagementofenterprisesandinstitutions,andvariousattendancesystemshavebeengraduallyappliedtothemanagementofattendance.However,theattendanceworkofteachersincollegesanduniversitiesisinarelativelyblankfield.Thetraditionalwayofattendanceoftenincreasesthemanagementcostofschools,increasestheworkloadofteachers,andalsotakesupacertainamountoftime.Basedonthis,themainworkofthispaperistodesignasetofcollegeteachersfortheattendancesystem,thesystemcanbemoreconvenient,fastforcollegeteachersforclassattendance.Thispaperfirstdescribestheresearchbackgroundandsignificanceofthesubject,introducesthebasicprinciplesoffacerecognitionandthemainfacedetectionandfacerecognitionmethods.Secondly,thehardwareplatformandsoftwarealgorithmaredesigned.HardwareplatformisaTMS320DM6437typeofDSP.Thesurroundingextensioncircuitisdesigned,suchaspowermodulecircuit,memorymodulecircuit,faceacquisitionmodulecircuitandIICmodulecircuit.ThesoftwarepartiscombinedwithOpenCVandothertoolstocompletethedesignofthecodeandtherealizationofthevariousfunctionalmodulesoftheattendancesystem,andthefunctiontestandperformancetestofthesystem.Thetestresultsshowthattheattendancesystemdesignedinthispaperhasabetterfacerecognitioneffectandattendancemanagementfunction,inlinewiththerequirementsofdemandanalysis,hasacertainusevalue.【Keywords】Facerecognition;Theteacher;AttendanceclockIII目录摘要..................................................................................................................................................IAbstract............................................................................................................................................II1.绪论...............................................................................................................................................11.1研究背景及意义.................................................................................................................11.2人脸识别技术现状.............................................................................................................12.相关技术介绍.........................................................................................................................
