摘要
An offset estimation device (40) includes a rotation axis calculation part and an offset estimation part. The rotation axis calculation part is configured to: obtain multiple sets of magnetic data detected by the magnetic sensor (20) and multiple sets of angular velocity data in accordance with the rotation amount of the offset estimation device (40); and on the basis of an arbitrary magnetic data group of the multiple sets of magnetic data and respective magnetic data corresponding to the magnetic data group, determine multiple rotation axes that pass through the center of a plane passing through the magnetic data group and indicate straight lines perpendicular to the plane. The offset estimation part is configured to estimate the offset of the magnetic data to be outputted from the magnetic sensor (20) on the basis of the multiple rotation axes.
