摘要
视频监控应用于社会生活各个领域,而远程视频监控更是研究的热点受到了极大的关注。文章采用ARM9为核心处理器,在移植Linux操作系统的基础上,搭建Web服务器,利用MJPG-streamer视频流服务器的相关功能,完成图像的采集、压缩、传输、显示。通过采用减小图像分辨率、改变像素色深、图像传输帧率和图像压缩率的方法减小数据传输时占用的带宽。解决了可能因为数据量过大而造成网络拥塞、延迟从而产生图像停顿、延时、误码等问题。最后用户可以在本地Web浏览器中实时监控远端的视频图像。
Video monitoring used in every field of social life,and remote video monitor is become the research focus received great attention.In this paper uesd the ARM9 processor as the core,and for it transplant a Linux operating system,then build a Web server,Use the MJPG-streamer streaming server related functions complete image collection,compression,transmission and display.By reducing image resolution,change pixel color depth,image transmission frame rate and the image compression ratio method to reduce the occupied bandwidth data transmission.Solve to probably because the amount of data is too large to network congestion,delay,resulting in Resulting image pause,delay,error,etc.Finally the user can in local Web browser in real time monitoring the distant video images.
