Title    Software development of regional intrusion detection based on video                                     

Abstract The traditional video monitoring system has a lot of inconvenience management place, due to the development of science and technology, gradually raise the standard of living, environmental security has been more and more important。 People have higher requirements, at this time it need to study a more efficient, and has the universal suitable of regional intrusion detection methods。

The main content of this paper is: the development of video based regional intrusion detection software。 Firstly, this paper introduces the background, research meaning and the tools used in the development of this project, and then explains the principle of the system。 The whole process, including target detection, target tracking, intrusion etc。 module involving background modeling, detection of foreground pixels, removal of noise and other steps, using the Gaussian mixture model, median filtering, Kalman filtering method, and in some important part enumerate the specific algorithm。

The software uses VC + + and OpenCV to design, in the previous algorithm based on test target invasion, completion of the algorithm, based on a given video surveillance area alert, when the target into the monitored area to on the monitor screen appears with the striking cue information and timely alarm。 In the event of abnormal situation in a timely manner to issue a warning or provide useful information, and thus effectively assist the security personnel to deal with the crisis。
