摘要
针对传统模拟视频监控中图像质量差、无法联网、不可移植等不足,设计了一种基于嵌入式Linux的智能家居远程视频监控系统。远程视频监控系统以ARM(Advanced RISC Machines)处理器S3C2440和Linux操作系统为核心平台。在内核中添加了各种所需的驱动程序,基于V4L2的应用程序对USB摄像头进行图像视频采集,采用TCP/IP网络协议,进行视频数据传输。主机端采用跨平台开发工具Qt开发应用程序,接收图像视频数据并显示图像视频。实验结果显示,能在远程端看到清晰流畅的视频流,系统运行稳定可靠。
Aimed at some shortages of the traditional simulation video monitor,such as bad quality image,unable to be online,unable to be transplanted and so on,design a smart home remoting video monitor system based on embedded Linux.The system uses embedded microprocessor ARM and Linux operating system as the core platform.Add all the necessary drivers in kernel.The application program of V4L2 captures image date by using a USB camera,and sends the image data based on TCP/IP.Qt cross-platform development tool is used by host computer to design a application to receive image date and display the image.The experimental results show that you can see the clear and smooth the video stream on computer.The system runs steadily.
