摘要
考虑到监控系统的方便与实用,提出了一种基于嵌入式单板电脑所开发的便携式图像监控系统。该系统以普通的USB摄像头作为图像采集设备,对比目前以CCD摄像头和采集卡作为采集设备的监控系统,体积大大缩小。通过一种有效的图像异常检测算法,对实时图像进行检测,有异常发生时,通过GPRS模块进行无线传输,将异常图像发送到远端,达到远程监控的目的。实验结果表明该系统实时性好、异常报警准确率高,实用性强。
Considering the convenience and practicability,a portable surveillance system based on the embed pc is presented. In order to reduce the volume of the system an ordinary USB camera is used to catch images instead of the CCD camera and image card. Real-time supervision is performed using an effective algorithm that can get the information whether there are objects in the acquired image. When the objects occur, the image will be sent away through GPRS module. Experiment results showed that the system possesses the advantages of real-time standard, high precision and practicability.
