Design And Implementation Of Intelligent Home Security System Based On Android Platform

With the development of society,people’s demands for the safety of family and property continue to improve,real time and intelligent security system application needs are also increasing.With the improvement of the hardware performance and the increase of storage space,the ability to calculate and process of smart phones and other mobile devices continue to improve,making it possible to realize the function of intelligent security system in the mobile terminal.At present,the update speed of the smart phone makes every family have more or less abandoned mobile phones without any problems,then we can install the application of smart security on these phones to achieve the "waste" recycling.The goal of this research is to design and implement a smart home security system based on Android mobile platform.Around the above objectives,the main research work of this paper includes the design and implementation of the human body detection,face detection and face verification in mobile terminal.Specific work is as follows:(1)Human detection in mobile terminal.Through the research of human detection technology and related algorithms,using the open source computer graphics and image visual library Open CV for Android and HOG features based method to realize the function of the human body detection in mobile terminal.(2)Face detection in mobile terminal.Combined with the performance and characteristics of mobile devices,through the comparison of a variety of face detection algorithms,this paper uses the Ada Boost algorithm based on Haar-like features to face detection,and realizes the face detection function in the mobile terminal.(3)Face verification in mobile terminal.On the basis of comparing the relevant algorithms of face recognition,the Fisherfaces algorithm based on Eigenfaces and Fisher is used to realize the face verification function in the mobile terminal.(4)The prototype implementation of intelligent home security system.Through in-depth study of the Android mobile system platform,based on the research of the above algorithm,a smart home security system based on Android platform is designed and implemented.In this paper,the smart home security system based on the Android mobile platform can achieve human detection,face detection and face verification and other functions,in this paper,aiming at this system has been tested on the Huawei honor 3C phone.Experimental results show that the stability and accuracy of the system meet the requirements,achieve the desired,but for practical application,system of real-time operation and convenience also need to improved.
