| 摘要 |
A position measurement apparatus includes a reference value acquisition unit that obtains a plurality of reference geomagnetism information pieces, the plurality of reference geomagnetism information pieces being geomagnetism information pieces measured at a plurality of reference positions, an association information generation unit that generates association information that associates the plurality of reference positions with the plurality of reference geomagnetism information pieces, a measurement value acquisition unit that obtains measurement geomagnetism information, the measurement geomagnetism information being geomagnetism information measured at a measurement position and a position specifying unit that specifies a position corresponding to the measurement geomagnetism information based on association between the plurality of reference positions and the plurality of reference geomagnetism information pieces obtained by the association information. |
