基于手机和GSM的远程自动视频监控系统

为满足小型私密场所安全监控的需要, 设计并实现了一套具有实时、 便捷、 易操作、 低成本和高可靠性的远程自动视频监控系统。从监控系统的功能原理出发, 由CMOS(Complementary Metal-Oxide Semiconductor Transistor)摄像头采集图像, 基于开源计算机视觉库(OpenCV： Open Source Computer Vision Library)对监控区域进行目标检测和人脸识别, 并结合视频中的运动信息形成触发条件, 使SIM900A模块把报警信息通过GSM（Global System for Mobile Communications）网络发送到用户指定手机上, 从而达到报警的目的。实验结果表明, 该系统作为计算机图像处理和GSM网络结合的一个典型应用, 目标闯入监控区域时能及时通过用户手机报警, 并且能有效避免噪声等干扰信息, 具有较强的可靠性和实用性。

Remote Automatic Video Monitoring System Based on Mobile Phones and GSM

In order to meet the demands of safety monitoring on small private workplace, this paper designs and implements a remote automatic video monitoring system with real-time, convenience, operability, low-cost and high-reliability. The system starts from the functional theory of the monitoring system, combines with the development of the computer image processing technology, captures image through a CMOS(Complementary Metal-Oxide-Semiconductor Transistor) cam
era, implements face recognition on the basis of OpenCV, and generates the trigger condition according to the result of face recognition and detection of moving
things in the videos. According to the trigger condition, the SIM900Amodule will send alarming message to the user specified phone via the GSM（Global System for Mobile Communications） network. As a typical application of the combination of computer image processing and GSM network, when the target breaks
into the monitored area, the system can give an alarm to the users phone in a timely manner, with high reliability and practicability by effectively handling
such interference as noise.
