摘要: 如今社会安全问题日益突出,传统的报警系统再也无法满足社会的需求,在这前提之下,国内外近几年都提出基于图像处理的智能报警系统,智能图像报警系统解决了传统报警系统的不足,并且逐步实现网络化、多媒体化。本论文也是基于图像报警的研究,通过设计完成监控并实现报警;本系统通过采用MATLAB编程实现监控报警功能,并且对图像去噪,灰度变换对数字图像进行处理等实验,通过调试,程序运行成功,实现自动报警功能并记录异常情况的图像,并对截获图像进行灰度变换。图像报警报警系统可实现实时监控,稳定性高,解决了传统报警系统的不足,有很大的应用前景。64994

Title The research of image alarm system
Abstract
Now, the problem of information society is becoming more and more important. the traditional alarm system can no longer meet the needs of society, under the premise, In recent years ,both inland and abroad are put forward based on image processing of intelligent alarm system,The intelligent image alarm system avoid the deficiency of the traditional alarm system, Gradually realizing networking,and multimedia. This thesis is based on the research of image alarm,Finally realizes the alarm function ; This system by adopting the MATLAB programming implementation monitoring and alarm function,Final program runs successfully, realize the alarm function, and record images of the abnormal situation,Image alarm alarm system can realize real-time monitoring, and has high stability, real-time monitoring,To solve the deficiency of the traditional alarm system,having a good application prospect.
