Abstract
An estimation method for estimating target region information relating to a target region by using an estimation device that estimates information including a position of a living body by using a radio wave includes: acquiring first information relating to lengths of a planar shape of the target region;acquiring second information relating to an installation state of a transmission antenna and a reception antenna included in the estimation device; acquiring third information relating to a trajectory defined by a plurality of positions of the living body estimated by the estimation device when the living body moves along a predetermined path in the target region; and performing at least one of (1) estimation of the planar shape by correcting the first information and (2) estimation of the installation state by correcting the second information based on the first, second, and third information acquired, as the estimation of the target region information.
