Document Type and Number:
Japanese Patent JP7023756
Kind Code:
B2
Abstract:
To provide a magnetic field estimation device capable of estimating a magnetic field at higher accuracy without carrying out additional measurement of an outside magnetic field, a demagnetization system, and a magnetic field estimation method.SOLUTION: A magnetic field estimation device applied to a structural body 1 having a plurality of magnetic sensors 2 includes: a division unit for dividing a three-dimensional structural model of the structural body 1 into a plurality of areas on the basis of positions of the plurality of magnetic sensors 2; a setting unit for setting a uniform magnetic state for every area; an estimation unit for estimating a magnetic field generated by the structural body 1 on the basis of the magnetic state of each area set in the setting unit and the three-dimensional structural model; and a division update unit for increasing the number of areas by further dividing at least one area which is divided by the division unit when a difference between a vector value or the strength in the magnetic field in the position of the magnetic sensor 2 estimated by the estimation unit, and the vector value or the strength in the magnetic field measured by the magnetic sensor 2 arranged in the position is greater than a preset threshold.SELECTED DRAWING: Figure 1
