MAGNETIC DATA CORRECTION DEVICE AND CORRECTION PARAMETER CREATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a magnetic data correction device and correction parameter creation device that can accurately remove influences of soft-iron effects from acquired magnetic data.SOLUTION: A magnetic data correction device comprises: a magnetic data acquisition unit 22 that acquires magnetic data; a correction parameter information storage unit 25 that plurally stores correction parameter information associated with a state of a magnetic data correction device 3 and a correction parameter for correcting the magnetic data; a state information acquisition unit 23 that detects the state of the magnetic data correction device 3; a correction parameter information selection unit 24 that selects the correction parameter information from the plurality of correction parameter information to be stored in the correction parameter information storage unit 25; and a magnetic data correction unit 26 that corrects the magnetic data using the correction parameter information selected by the correction parameter information selection unit 24.
