摘要
A position detection apparatus includes: a distance calculation unit configured to calculate a first distance between each of a plurality of receiving antennas and the capsule endoscope based on each reception strength of a signal received by the plurality of receiving antennas, a total distance calculation unit configured to calculate a total sum of distances from spherical surfaces inside a region where at least three or more spheres out of a plurality of spheres are overlapped, each of the plurality of spheres having a center at each of the plurality of receiving antennas and having a radius of the first distance, and a position determination unit configured to detect, as the position of the capsule endoscope, a position where the total sum of distances from the spherical surfaces is minimum.
