基于ARM9的自适应背景差法智能远程视频监控系统

摘要

With the application of video surveillance system more widely ,S3C2440 microprocessor-based high performance and lowcost intelligent remote video monitoring system was introduced .From the system as a whole on the functional principle of the sys-tem ,the design of hardware and software modules section was introduced .The related moving object detection algorithm was studied and an adaptive background subtraction was put forward to complete intrusion detection .After GPRS alarm,LAN transmission net-work can get real-time video data , so as to achieve the purpose of remote intelligent surveillance .Through testing , the system is compact and flexible ,and has high reliability and low cost relative to traditional video surveillance systems .%介绍了一种基于S3C2440微处理器的高性能、低成本的智能远程视频监控系统。从系统整体出发阐述系统的功能原理、部分软硬件模块的设计方案；研究了运动目标检测相关的算法，并提出一种自适应背景差法完成入侵检测。GPRS报警后，通过局域网传输使得网内计算机可以实时获得视频数据，从而达到远程智能监控的目的。通过测试，系统小巧灵活，布线方便，可靠性高，与传统的视频监控系统相比成本低廉。
