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.
