基于嵌入式的移动图像监控系统设计

Motion Images Monitoring System Based On Embedded

摘要:

随着科技水平的提高和经济的快速发展,人们对于如何保护自身安全和经济财产等方面的问题越来越重视。针对这些情况,设计了一种能够实现远程监控并可以自动预警的设备。设备使用TQ210开发板作为硬件平台和嵌入式Linux作为软件平台,通过外接的摄像头采集图像,利用帧差法对采集到的图像进行处理,从而实现对运动物体的检测,最后通过音箱播放警报声以实现预警。同时在开发板上构建了以Boa为核心的WEB服务器。此设备通过Wi-Fi模块,实现了远程查看移动物体图像和视频的功能。实验结果表明,该系统不仅实现了传统的视频实时监控功能,而且当检测到移动物体产生时,不仅能够立即开启声音预警,并将图像和视频保存下来用于用户事后的查看或者取证。

Abstract:

With the improvement of technology and economic development, people are more and more attention to the protection of personal and economic property. Aiming at this situation, designed an equipment which can realize remote monitoring and automatic broadcasting the alarm sound. The equipment takes the TQ210 board based as the hardware platform and the embedded Linux as the software platform and the image was captured by the camera and compared with the frame difference to achieve the detection of moving objects and using speakers to broadcast the alarm sound. At the same time, the WEB server is constructed with Boa as the core on the board to achieve a remote view the images and videos of the moving objects.The experimental results show that the system not only to achieve the traditional real-time video monitoring, and when it detects moving objects produce, it can immediately turn on the sound warning and save the images and video down for the user to view afterwards or obtain evidence.
