    摘要: 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.

    摘要: A method and system for deploying a magnetic distortion rejection map of an indoor area. The method comprises generating, using a processor, (i) a first distribution of magnetic fingerprint data that includes magnetic distortion data points based at least in part on a set of positions traversed by a plurality of mobile devices within the indoor area, and (ii) based on accessing a position correction factor, a second distribution of magnetic fingerprint data that includes true position data points corresponding to the magnetic distortion data points, receiving, at the memory, a set of magnetic fingerprint data that includes a second set of magnetic distortion data points based on an additional set of positions traversed by at least one additional mobile device within the indoor area, processing the second set of magnetic distortion data points, the first distribution and the second distribution to generate an updated distribution of magnetic distortion data points, and if the updated distribution exceeds a threshold density of magnetic distortion data points, deploying the updated distribution as the magnetic distortion rejection map of the area.

    摘要: A method and a device for tracking an item using a tracking device associated with the item are described. The method, executed in a processor of the tracking device, comprises identifying a location state of the tracking device as one of an indoor location and an outdoor location relative to an indoor facility, based on at least one of satellite based data and connectivity to an access point in the indoor facility. Upon identifying the location state as the indoor location, a wireless transceiver and one or more sensor devices may be activated. The sensor devices may include at least one of a wireless signal strength sensor, a wireless signal connectivity sensor, an inertial sensor, a magnetic field sensor, a barometric sensor, and an ambient light sensor. Further, indoor localization data gathered by the sensor devices may be provided for localization.
