摘要 |
A noise pattern acquisition device a position detection apparatus (100) according to an aspect of the present invention includes: a geomagnetic sensor (103); a coordinate estimation unit (107) configured to estimate current position coordinates; and a geomagnetic noise pattern management unit (108) configured to, when an abnormality occurs in a magnetic field strength detected by the geomagnetic sensor (103) during movement of the noise pattern acquisition device (100A), store in a geomagnetic noise pattern storage unit (109) a geomagnetic noise pattern which is a pattern representing a time-series change of the magnetic field strength detected by the geomagnetic sensor (103). This makes it possible to not only acquire a geomagnetic noise pattern but also detect a proper position with a simple structure and process at reduced cost. |
