LOCATION DETECTION DEVICE, CAPSULE ENDOSCOPE SYSTEM, AND CAPSULE ENDOSCOPE LOCATION DETECTION PROGRAM

摘要

Provided are a capsule endoscope location detection device having a given precision while controlling measurement quantities, a capsule endoscope system comprising the location detection device, and a capsule endoscope location detection program. An information processing device (6) comprises a location information estimation unit (62) which derives a first distance (rn) which is the distance between each of a plurality of receiving antennae to a capsule endoscope based on the receiving strength of the signal which each receiving antenna receives, and within a region wherein a plurality of spheres with the distance (rn) corresponding to each receiving antenna wherein each receiving antenna is the center thereof being the radius of each sphere overlap, estimates the location whereat the sum of the distances from each spherical surface is the shortest to be the location of the capsule endoscope.
