摘要
为了扩大单个摄像头的视频监控范围及灵活性,设计了一种可远程操控的移动视频监控系统.该系统由四个模块组成,基于Arduino系统的智能车搭载有摄像头,接收用户指令,用于移动视频的采集;嵌入式Linux系统通过V4L2接口实现对视频数据的实时采集,一方面将数据通过网络发送至转发服务器,另一方面将来自用户的控制指令转发至智能车;服务器则用于转发视频至客户端以及转发用户控制指令至Linux系统;基于Android的移动端呈现监控视频并提供用户控制界面.与现有系统相比,该系统可使用单摄像头实现无死角监控.
A remote-control mobile video surveillance system is designed to expand the video monitoring range and enhance flexibility of a single camera.The system is composed of four modules.The smart car based on the Arduino system is equipped with a camera to receive user instructions for collecting videos.The embedded Linux system makes real-time acquisition of video data feasible through the V4L2 interface.Meanwhile,it sends the data to the forwarding server through the network and forwards the control commands from users to the smart car.The server ransmits the video to the client while the user control instructions to the Linux system.Additionally,Android-based mobile terminal presents monitoring videos and provides a user control interface.Compared with the existing system,the new system enables monitoring without blind spots by a single camera.
