Abstract: A temperature sensing system senses a temperature in the monitor space. The temperature sensing system includes a first detector, a second detector, and a processing unit. The first detector detects a temperature on a ceiling and outputs first information about the temperature on the ceiling. The second detector detects infrared radiation emitted from a floor and outputs second information about the infrared radiation from the floor. The processing unit calculates, based on at least the first information and the second information, a spatial temperature distribution which includes a component in a height direction with respect to the monitor space between the ceiling and the floor.

Abstract: An aspect of the present disclosure is to accurately estimate whether or not a plurality of people are in close contact with each other in a target space. An estimation system (1) includes a first estimator (12) and a second estimator (13). The first estimator (12) is configured to estimate, based on a heat distribution including a plurality of heat sources detected by at least one infrared sensor (2), three-dimensional positions of heads of a plurality of people in a target space. The second estimator (13) is configured to estimate, based on data on the three-dimensional positions estimated by the first estimator (12), estimate whether or not the plurality of people are in close contact with each other.

Abstract: An infrared processing system includes a first thermal image generating unit, an object extracting unit, a second thermal image generating unit, and an object temperature calculating unit. The first thermal image generating unit generates, using a first temperature correction value, a first thermal image based on the output signal of the image sensor. The object extracting unit extracts the object from the first thermal image. The second thermal image generating unit generates, using a second temperature correction value corresponding to the object that has been extracted by the object extracting unit, a second thermal image based on the output signal of the image sensor. The object temperature calculating unit calculates, based on the second thermal image that has been generated by the second thermal image generating unit, a temperature of the object that has been extracted by the object extracting unit.
