Abstract:
1. An in-room probability estimating apparatus comprising: a detection information collecting unit to collect detection information of human bodies present in plural rooms, from an external apparatus; a movement probability calculating unit to calculate movement probabilities at which at least one of individual persons moves from one of two rooms to the other and from the other room to the one room, based on a time difference between human body detections for two rooms and a between-room movement parameter having a value depending on a movement distance between the two rooms; and an in-room probability updating unit to calculate, for each of the rooms, a first movement probability and a second movement probability of each of the individual persons based on the movement probabilities calculated by the movement probability calculating unit and an in-room probability of each of the individual persons for each of the rooms, the first movement probability being a movement probability at which each of the individual persons moves from the room to each of the other rooms and the second movement probability being a movement probability at which each of the individual persons moves from each of the other rooms to the room, and update the in-room probability of each of the individual persons for each of the rooms based on the first movement probability and the second movement probability.
