摘要随着网络通信技术和视频编解码技术的不断进步，视频监控系统也不断发展。目前，第三代视频监控技术即网络视频监控技术已经占据市场主流，人们对移动视频监控系统的市场需求也在日益扩大。与此同时，安卓智能手机市场飞速发展，安卓手机更新换代速率由以前的一年一代到如今的半年一代甚至三个月一代。移动设备的性能已经完全可以满足视频监控的硬件要求，而已经广泛应用的第四代移动通信技术和无线局域网技术完全可以满足传输高清网络视频的要求。因此，开发一个基于安卓手机的移动视频监控系统完全可行。本文研究了基于安卓系统的视频监控实现所需要的技术，包括视频编解码技术，视频传输技术，流媒体播放，安卓界面设计等相关知识。本监控系统包括视频采集端和视频播放端。视频采集端利用安卓手机的相机作为网络摄像头，实时采集监控数据，视频采集端采用MPEG编码技术对采集的图片进行编解码，并采用HTTP技术传输视频流。安卓客户端利用了基于VLC流媒体库的播放技术，可以远程实时播放摄像头监控的视频。经过在一加手机和华为手机上测试，本视频监控软件具有良好的表现，性能和清晰度均达到设计要求，能够很好的实现视频监控功能。关键词：视频监控；安卓系统；MPEG；HTTP-I-DesignandimplementationofmobilevideomonitorsystembasedonAndroidAbstractWiththenetworkcommunicationtechnologyandvideocodectechnologycontinuestoprogress,videomonitorsystemisalsoevolving.Atpresent,thethirdgenerationofvideomonitortechnologyhasoccupiedthemainstreammarket,peopledemandonthemobilevideomonitorsystemmarketisalsoexpanding.Atthesametime,Androidsmartphonemarket,therapiddevelopmentofAndroidmobilephonereplacementratefromthepreviousgenerationtotoday'ssemi-annualgenerationoreventhreemonthsgeneration.Mobiledeviceperformancehasbeenfullymeetthehardwarerequirementsofvideomonitor,andthefourthgenerationofmobilecommunicationtechnologyandwirelessnetworktechnologymeettherequirementsofhigh-definitionvideotransmission.Therefore,thedevelopmentofamobilephonebasedonandroidmobilevideomonitorsystemisfeasible.ThisarticlehasstudiedthetechnologyneededforAndroidvideomonitorimplementation,includingAndroidinterfacedesignlanguage,videocodectechnology,videotransmissiontechnology,streamingmediaplaybackandotherrelatedknowledge.Themonitoringsystemincludesvideocaptureandvideoplayback.VideoacquisitionusingAndroidmobilephonecameraasawebcamera,real-timeacquisitionofmonitoringdata,videoacquisitionusingMPEGencodingtechnologytocapturetheimageencodinganddecoding,andtheuseofHTTPtechnologytotransmitvideostreams.VideoplayerusesaVLCstreaminglibrarybasedontheplaybacktechnology,youcanremotelyplaythecamerareal-timevideorecording.Bytestingonmobilephone,thevideomonitorsoftwarehasagoodperformance,performanceandclarityaredesignedtomeettherequirements,itcanbeaverygoodvideomonitorfunction.Keywords:VideoMonitor;AndroidSystem;MPEG;HTTP-II-目录摘要.....................................................................................................................................IAbstract......................................................................................................................................II绪论.........................................................................................................................................11.1课题来源......................................................................................................................11.2国内外研究状况..........................................................................................................21.3项目目标...................
