Abstract
A method and system of instantiating a recalibration of a magnetic fingerprint dataset of indoor facilities or infrastructure for mobile device navigation. The method comprises, based on magnetic parameters acquired from a plurality of mobile devices acquired at a set of positions within an indoor area, accumulating the magnetic parameters in accordance with a trained neural network-based magnetic fingerprint dataset in a fingerprint database of the indoor area, identifying respective positions of a subset of the set of positions having a variance that exceeds a threshold variance between observed magnetic parameters and magnetic parameters determined in accordance with the trained neural network, and when contiguous positions of the subset are encompassed by a boundary representing a portion of the indoor area, instantiating a re-calibration of the magnetic fingerprint dataset for mobile device navigation within the portion of the indoor area.
