【摘要】：随着计算机技术的快速发展和互联网的不断普及,我国视频监控行业的发展取得了巨大的突破,它的应用领域已经扩展到各行各业,并逐渐渗透到人们的日常生活中,未来监控行业的发展也将朝着多元化和智能化的方向发展。目前的监控系统一般采用C/S模式开发,但其暴露出来的问题越来越多,如系统升级复杂、维护费用高,本文针对C／S模式监控软件的不足,设计和实现了一种基于WEB网络的视频监控客户端软件。它以浏览器为客户端,利用嵌入式设备采集H.264视频流,依靠无线网络传输,传输协议采用RTP/RTCP协议,视频监控客户端软件的交互信令采用TCP/IP网络协议,最后通过DirectShow在浏览器中嵌入ActiveX控件来播放视频。符合监控行业目前的市场需求和未来的发展趋势,具有较好的实用价值。主要内容如下： 1.针对C/S模式监控软件的不足,提出一种B/S模式监控软件的总体设计方案。按模块分别对前端设备、Web服务器和Web客户端进行总体的设计,重点设计Web客户端,包括用户操作界面的设计,ActiveX控件的设计和CGI程序的设计。 2.根据监控软件的功能需求,提出一种B/S模式监控软件的具体实现方案。包括两部分：第一部分是用户操作界面的实现,包括用户登录界面、视频播放主界面和视频信息配置界面；第二部分是监控软件功能模块的实现,包括视频模块、音频模块和移动侦测模块。 3.针对视频监控软件图像放大后物体边缘会产生锯齿状的问题,提出一种视频质量改进的算法研究方案。通过在视频播放平台DirectShow中插入双线性插值算法,改进CIF格式视频放大四倍后的图像,对改进后的结果进行仿真,并进行视频图像质量的评估。
[Abstract]:With the rapid development of computer technology and the continuous popularization of the Internet, the development of video surveillance industry in China has made a huge breakthrough, its application field has been expanded to various industries, and gradually penetrated into the daily life of people.The future development of the monitoring industry will also be diversified and intelligent development direction.The current monitoring system generally uses C / S mode to develop, but it exposes more and more problems, such as complex system upgrade, high maintenance cost, this paper aims at the shortage of C / S mode monitoring software.A video surveillance client software based on WEB network is designed and implemented.It takes browser as client, collects H.264 video stream by embedded device, relies on wireless network transmission, adopts RTP/RTCP protocol for transmission protocol, and adopts TCP/IP network protocol for interactive signaling of video monitoring client software.Finally, DirectShow embedded in the browser ActiveX control to play video.In line with the current market demand and future development trend of the monitoring industry, it has good practical value.The main contents are as follows:1.Aiming at the shortage of C / S mode monitoring software, this paper puts forward an overall design scheme of B / S mode monitoring software.According to the module, the design of the front-end equipment web server and the Web client is carried out, especially the Web client, including the design of the user interface and the design of the CGI program.2.According to the functional requirements of the monitoring software, a specific implementation scheme of the B / S mode monitoring software is proposed.It includes two parts: the first part is the realization of the user operation interface, including the user login interface, the video playback interface and the video information configuration interface; the second part is the realization of the monitoring software function module, including the video module.Audio module and mobile detection module.3.In order to solve the problem that the edge of the object is jagged when the image is magnified by video surveillance software, a video quality improvement algorithm is proposed.The bilinear interpolation algorithm is inserted into the video playback platform DirectShow to improve the image magnified by four times in CIF format. The improved result is simulated and the quality of video image is evaluated.
