Description: 本文针对远程监控提出了一种结合IP网络的监控技术方案,系统总体架构采用S3C2410、USB摄像头与Linux操作系统组成嵌入式软硬件系统。并通过摄像头采集到的数据经过FFMPEG软件提供的H.264处理函数处理,数据转换后交给处理线程处理,采用双线程实现视频的数据的处理和传输。同时利用S3C2410网络模块,把图像数据转化为IP数据报通过RJ45接口在Internet上传输,实现远程监控。
关键词:视频采集,IP网络,Linux,H.264,远程监控
-Abstract: This paper presents new technology program with IP network sources giving to the traditional remote monitoring .this system using S3C2410,USB camera and Linux operator system to Set up the hardware system. The data from USB’s Camera is dealed with API of H.264 which is provided by FFMPEG bag, the data is convered then which is transferred to processing thread, this system uses Dual-threaded to come true the processing and transmission of the data. at the same time, using S3C2410’s net-module Image’s data transforming IP data package through the RJ45 interface are transmitted on the Internet, and achieving remote monitoring.
