基于Internet的嵌入式视频监控系统的设计与实现

Design and Realization of an Embedded Video Monitoring System Based on Internet

该文以ARM9微处理器和嵌入式Linux系统作为开发平台设计并实现了一个视频监控系统,系统基于Brower/Server结构,使用Boa作为嵌入式Web服务器完成视频数据在Internet上的传输。介绍了系统硬件平台和软件平台的搭建过程,详细讨论了使用Video4Linux编程接口完成对视频数据的采集过程,以及利用JPEG标准对视频数据进行压缩的方法。测试结果表明系统功能及性能基本满足应用要求。

An embedded video monitoring system, which takes ARM9 microprocessor and embedded Linux operating system as development platform, is designed and realized in the paper. The system based on Brower/Server structure, using Boa as embed- ded Web server completes the transmission of video data over the Internet. The building process of system hardware and software platform is introduced. The process of video data collection using Video4Linux programming interface and the method of using JPEG to compress the video data are discussed in detail. The test results show that the function and performance of the system can meet application requirements.
