基于Android和嵌入式Web的视频监控系统的研究与实现

摘要

In order to solve the issues at traditional video monitoring system, such as difficulty in cable laying and high cost, an idea of video monitoring system based on Android platform is proposed, which combined with Android and embedded Web server. This scheme uses wireless networks to communication,and meets the requirements of mobility and real-time. The integral framework of the system and a kind of embedded Web server named i-jetty are introduced. The paper emphatically discusses the acquisition and processing of the video data, the method of PTZ (Pan/Tilt/Zoom)control and the realization of timing record. The system runs well on REAL210(V6.2)and the delay of video is about 5 seconds.%针对传统视频监控系统布线难、造价高等问题，结合Android操作系统和嵌入式Web服务器，提出了在An-droid平台下搭建视频监控系统的设计方案，该方案采用无线网络通信，满足了视频监控移动性、实时性的需求。文章阐述了监控系统的整体框架，介绍了i-jetty嵌入式Web服务器，重点描述了监控系统视频数据的获取过程、摄像机云台控制方法以及定时录像功能的实现。该系统在嵌入式设备REAL210(V6.2)上运行良好，视频延时5秒左右。
