摘要
设计实现了一种基于S3C2440平台,应用于实时监控周边环境情况,能够保障个人及社会财产安全的视频监控系统。系统通过QT集成开发环境在Linux中进行开发,应用于嵌入式Linux平台。系统根据Linux系统中的V4L2协议实现图像采集模块并通过QT的Label控件直接显示,采用UDP协议完成视频传输模块,在视频处理模块移植x264对数据进行编码压缩以mp4格式封装保存,移植开源软件MPlayer制作视频播放器实现视频回放功能。整个系统实现了嵌入式平台视频监控的基本功能,能够记录历史并显示实时图像,并且远程查看实时图像。
Design and implementation of a S3C2440 based platform, used in real-time monitoring of the surrounding environment, to protect the personal and social property security video surveillance system. System through the Qt integrated development environment in the Linux platform for development, applied to embedded Linux platform. System image acquisition module implemented under Linux v412 protocol and by QT label controls directly to the display, using UDP protocol to complete the video transmission module. In the video processing module transplant x264 on data compression coding in MP4 format package preservation and transplantation of open source software Mplayer making video video playback function. The entire system realizes the basic function of the embedded platform monitoring, which can record the history and display the real-time image, and the real-time image. player video
