| Abstract(in English) | With the current spread of COVID-19, there has been a growing interest in monitoring behavior of people to control the spread of infectious diseases indoor. In addition, in recent years, the probability of evacuation of residents to refuges has increased due to natural disasters such as earthquakes and typhoons. So far, the existing studies have proposed tracking systems for the indoor position of individuals using a wireless tag which is linked to personal information or LiDAR. However, it is difficult to prepare enough tags before the occurrence of the disaster, and it is impossible to identify each person by the observation with LiDAR. Therefore, in this system, we propose a new tracking system that identifies individuals in each direction by deploying microphones of estimating the direction of sound source on multiple locations and by analyzing the voiceprints. In addition, by installing LiDAR, the system observes the three-dimensional structure in the area to be observed and identify the location of people in real time. Furthermore, by combining these observations, the system achieves the tracking of individuals indoor and detects the intensive contact among users. By the proposed system, the location and behavior of users can automatically be tracked even if they do not possess specific devices, and the facility managers can check the visualization of the tracking results. |
