摘要
研究一种用于多区域视频监控的智能入侵报警方法。该方法以多线程技术为基础,采用基于混合高斯背景建模的移动侦测算法实现多个区域实时入侵报警;采用视频监控卡自带函数库实现监控视频的显示。提出了剪贴板完成视频数据流的截取和数据格式的转换,避免了硬盘的反复读写,提高了监控画质和程序运行速度。最后给出了实验结果,结果表明该方法能有效的对入侵目标进行检测报警,且误报率较低,为1%～2%。
In this article, an inteligent intrusion alarm method for muhizone video monitoring was explored. The method which is based on multithread technology adopted the motion detection algorithm which is based on mixed Gaussian background modeling to realise real-time muhizone intrusion alarm; the embedded function library of the video monitoring card was adopted to display the monitoring video;in the paper the interception of video data flow and conversion of data format were finished through clipboard, repeated reading and writing of the hard disk were avoided, the monitoring picture quality and the processing speed of the program were improved. At last the experiment＇ s result was got,and the result shows that the method can do detection alarm to intrusion object with high effeeiency and low false alarm rate,between 1%-2%.
