Estimation of human posture by multi thermal array sensors

This paper describes a human posture estimation system by using two thermal array sensors. In the system, the sensors are attached to ceiling and wall of a room, and acquire temperature distributions by 16 × 16 elements. The temperature distributions represent a state of temperature in the room, and they are analyzed to estimate human posture. Human posture is estimated 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 estimated human posture.
