Hard iron distortion和soft iron distortion

WebThe underlying algorithm in magcal determines the best-fit ellipsoid to the raw sensor readings and attempts to "invert" the ellipsoid to produce a sphere. The goal is to generate a correction matrix A to account for the soft-iron effect and a vector b to account for the hard-iron effect. The three output options, 'eye', 'diag' and 'sym' correspond to three … Webdistortions and soft iron distortions. Hard iron distortions are made by materials that produce a constant magnetic field which is in superposition with the earth magnetic field. …
