Research On Embedded Empty Nest Elderly Abnormal State Monitoring System Based On Visual Information Fusion

With the development of embedded system,the development of network technology and computer vision technology,the future we will realize: at any time,anywhere,through any network access mode,realize intelligent one or more need to operate.The arrival of the aging society,the increase in the elderly population,health care issues need urgent technical products to solve the Empty Nester.The design of intelligent monitoring system and embedded system based on computer vision technology,can realize data information and control related equipment access through the network,it can meet some special needs of the people to a certain extent.This subject provides a new web viewing scheme based on ZigBee heart rate detection,that uses the Pulse Sensor to collect the heart rate data of the elderly,the ZigBee sensor network to transmit the data the main processor,and determines whether the heart rate data is abnormal.In the meantime,the scheme also achieves the functions of the switch control of the lamp,the detection of temperature and humidity and the operation of the camera,ect.,realizes the real intelligent home management and monitoring of the abnormal condition of the elderly.On the basis of the realization of heart rate detection,this subject also provides a brand new PDA device viewing scheme based on people’s experience of falling detection,which is achieved by calculating the target tracking ellipse area in accordance with the CamShift target tracking algorithm,using this target tracking ellipse area to characterize the elderly physical features,finding out the center point and the lower vertex of the elderly and then determining whether the elderly falls by judging the acceleration,the angle,the difference in height and the residence time of these two feature points.The experimental results show that the proposed scheme can reduce the computational complexity while achieve better detection results under the premise of ensuring a high accuracy.The embedded intelligent monitoring system is a preface subject that researched at home and abroad,and the process of aging population in our country is also accelerating,with the continuous development of economy and the refined needs of people,it is foreseeable that the embedded intelligent abnormal exception monitoring system products will have great commercial value and social value.it can be expected that the embedded intelligent monitoring system will be of great commercial value and social value.
