Behavior Analysis And Service System Of Dense Crowd Based On WIFI

With the increasing number of large public places,the frequency of people's participation in social public activities is increasing.Behavior analysis and service system of dense crowd based on WIFI is an effective means of effective crowd monitoring.Building a perfect crowd monitoring service in public places is also of great practical significance.The thesis stduies the crowd behavior analysis system,we first gives the definition of group behavior analysis,discussing the research status of crowd behavior analysis.Then we analysis the crowd behavior based on the location information.Based on the obtained location data,we process the data message and get the boundaries of densely populated areas in grid environment.We also track and record the motion information in dense areas.Finally we give a service system for managers to supervise the crowd.From the point of view of the processing method,we use gird layout on the scene graph,preprocessing the crowd scene.Then we shoud to process the data and classify it.Then we calculate the motion of the crowd incuding the speed and direction parameters.Servers acquire the crowd area on grid area.Different intensive group transformation corresponds to different services.The service system provides data query and output to manager.It can alarm in case of emergency,and realize the function of intelligent monitoring for crowd behavior.
