A falling detection system with plural thermal array sensors

This paper describes a falling detection system by using two thermal array sensors. In the system, the sensors are attached to the ceiling and wall in a room, and acquire temperature distributions by each 16 × 16 pixels. The temperature distributions represent a state of temperature in the room, and they are analyzed to detect human falling. The falling is detected by time-series posture transition diagram and the sum of temperature. In our experiment, we measured the temperature distributions in a room modeled as private room in a nursing home. As the results, the system successfully detected the falling.
