摘要
近年来,视频监控系统得到了迅速的发展和广泛的应用,将嵌入式技术用于视频监控是其发展的趋势和方向。基于实际的开发需求,设计了一种基于嵌入式Linux的无线视频监控系统,该系统由服务器和客户端两部分组成。服务器通过video4linux接口循环地采集视频并进行MJPEG压缩,然后采用基于802.11g的无线传输协议发送视频。客户端不断地接收视频并进行解码,然后调用SDL在客户端的计算机屏幕上播放监控画面。经测试,该系统实现了视频的实时传输。
In recent years,video surveillance system has achieved high-speed development and wide application.The embedded systems into the video transmission and surveillance have become a new trend.In the light of practical requirements,wireless video monitoring system based on embedded Linux is designed,composed of server and client.The server,through Video4Linux interface,circularly collects the video image and implements MJPEG compression,then the video is transmitted by the wireless transmission protocol based on 802.11g,while the client receives and decodes the video constantly,then with SDL,displays the video image on the screen of client computer.Test indicates that this system could realize the real-time video transmission.
