Research And Implementation Of Mobile Video Surveillance System For Home Security

With the increasing awareness of home security,indoor mobile intelligent video surveillance technology plays an important role in the field of security applications,besides,monitoring and identifying people’s indoor abnormal behaviors effectively is always the difficult point of research.Based on the convenient,mobile and compositive intelligent terminal,this paper put forward that plant the abnormal behavior detection arithmetic of home security into the platform of intelligent mobile phones,which will change the traditional way of video surveillance,improving the flexibility and instantaneity of video identifying system.Meanwhile,mobile Internet and Internet technology will be utilized synthetically to improve the alarm function of video surveillance identifying system.This paper analyzes function needs of mobile video surveillance identifying system designed for home security,mainly in three aspects,that is,abnormal behavior detection arithmetic of home security,visual detection and identification of abnormal behaviors designed for intelligent mobile phones and the alarm function based on mobile Internet and Internet technology.This paper is mainly divided into three parts:Firstly,according to two common abnormal behaviors of home security,that is,abnormal burglary and the indoor tumble behavior of old man alone,an indoor abnormal behavior detection arithmetic of indoor video surveillance is put forward in this paper.This arithmetic combines these two identification arithmetic of abnormal behaviors,which decreases the redundancy and complexity of detection arithmetic.This detection arithmetic detects the abnormal burglary through reasonably judging the size of moving target.If the detection arithmetic conforms to reasonable standards,it judges the moving target being abnormal and indoor burglary happening.Besides,based on confirming the ratio of width and length of the abnormal moving target,the change rate of gravity and the state maintenance mechanism are used to correct the detection result,thus improving the reliability of the detection system.This arithmetic has low complexity,high efficiency,high reliability and good adaptability.Secondly,in order to make full use of the hardware resource of the idle smart phones and further improve the real-time,mobility and convenience of indoor abnormal behavior detection and recognition,we research deeply on the visual inspection of abnormal behaviors,and realize the collection of original photos,detection arithmetic of abnormal behaviors related to home security,the display of image results as well as the system alarm mechanism.The visual detection and recognition system for abnormal behavior of smart phones avoids the constraints of the traditional video surveillance behavior detection,such as installation cost,convenience and real-time.Finally,this system improves the arithmetic of abnormal behaviors related to home security and the single alarm mechanism of SMS(Short Messaging Service).Besides,the function of abnormal behaviors’ detection and the function of alarm information are integrated in the same application system,which finally realizes the system of mobile video monitoring related to home security.In the process of system optimization,modified detection arithmetic of abnormal behaviors related to home security synthetically utilizes the light environmental sensors of smart phones,which improves arithmetic of abnormal behaviors’ anti-interference performance of the variety of light intensity;the improving system combines the positive SMS alarming method with passive photo alarming method,which improves the function of alarming system.
