Abstract
A method and system of maintaining a trained neural network for mobile device indoor navigation and positioning. 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; and when a density of points represented by the set of positions having accumulated magnetic parameters exceeds a deployment threshold density, deploying the magnetic fingerprint dataset within a fingerprint map for mobile device navigation of the indoor area, the fingerprint map encompassing the set of positions.
