局域网视频监控系统的设计

Q260046902专业做论文I局域网视频监控系统的设计摘要：视频监控融合了信息技术、计算机技术、网络技术以及流媒体技术，一直是人们关注的应用技术热点之一，它以其直观方便、信息内容丰富而被广泛应用于许多场合。本文针对视频捕获和传输回放的功能要求，讨论了其软件系统的主要任务及解决方案。视频采集部分使用VFW函数进行。数据传输部分采用UDP协议，它提供面向无连接，不可靠的通信，相较于TCP有传输速率高，延迟小的优点。本文的视频采集、传输和显示是基于MicrosoftVisualC++6.0环境，利用MFC开发的。VisualC++作为一个可视的集成开发工具，提供了软件代码自动生成和可视化的资源编辑功能。与传统的一些编程平台相比，它能够使系统具有较高的效率和可用性。初步的实验结果表明，该软件系统在主要的功能上已接近实用化，并且操作简便、工作可靠。关键词：VFW；UDP；WinSockQ260046902专业做论文IITheDesignofLAN-VideoMonitoringSystemAbstract:VideoMonitoringhasamalgamatedtechnologyofinformation,computer,networkandmediastream.Sopeoplegivemuchattentiontovideomonitoringeverytime.Ithasbeenahotspotbecauseofitsconvenienceandabundanceinformation.Thisarticlediscussedthetaskandsolutionaboutvideocapture,transmissionanddisplay.VideodatahasbeencapturedsuccessfullybyVFWanduseprotocolofUDPwhentransport.UDPprovideconnectionlessanduncertaintycommunication.ComparedwithTCP,UDPhashighspeedandshorttimemeasurement.Videocapture,transmissionanddisplayarebasedonthedevelopmentenvironmentofMicrosoftVisualC++6.0andprogrammedbyMFC.VisualC++6.0isavisualizedintegrateddevelopmenttool,whichcanproducesoftwarecodeautomaticallyandsuppliedintegratededitor.Ithashigherefficiencyandmoreusabilitythantraditionalprogrammingterrace.Experimentresultshowsthatthissoftwaresystemisnotonlypractical,butalsohassimplyoperationandreliablework.Keywords:VFW,UDP,WinSockQ260046902专业做论文III目录第1章绪论...................................................................................................................11.1课题背景..............................................................................................................11.2课题的发展现状..................................................................................................11.3课题目的和意义..................................................................................................31.4论文的主要内容..................................................................................................3第2章基本概念介绍.......................................................................................................42.1VC++介绍............................................................................................................42.1.1C++............................................................................................................42.1.2VC++.........................................................................................................42.2MFC简介.............................................................................................................52.3VFW的体系结构................................................................................................52.4TCP/IP协议简介.................................................................................................62.5SOCKET套接字..................................................................................................82.5.1SOCKET套接字的引入...........................................................................82.5.2异步非阻塞...............................................................................................92.6本章小节..............................................................................................................9第3章局域网视频监控系统方案设计.........................................................................103.1系统总体方案设计............................................................................................103.2视频捕获方案的设计........................................................................................113.2.1视频捕获方案的选择.............................................................................113.2.2AVICap窗口类.......................................................................................123.2.3视频传输软件流程的设计.....................................................................133.3视频传输方案设计............................................................................................143.3.1传输层协议的选择.................................................................................143.3.2UDP协议的详细介绍............................................................................153.3.3套接字方案设计.....................................................................................173.3.4视频传输软件流程的设计.....................................................................17Q260046902专业做论文IV3.4视频回放方案设计............................................................................................183.4.1视频回放方案选择.................................................................................183.4.2位图信息头介绍.....................................................................................183.5开发平台和工具的选择....................................................................................203.6本章小节............................................................................................................20第4章局域网视频监控系统实现.................................................................................214.1视频采集实现....................................................................................................214.1.1视频捕获..............................
