Mobile device for estimating location using particle filter generated based on three-dimensional (3D) magnetic field map and method using said mobile device
Abstract:
A mobile device includes a magnetic field sensor configured to measure a magnetic field value at a location of the mobile device, and a memory configured to store first magnetic field maps corresponding to a number N of respective heights. The mobile device includes a magnetic field map deriving unit configured to derive second magnetic field maps corresponding to a number M of respective heights based on the first magnetic field maps, the number M being greater than the number N, and a location determining unit configured to determine the location of the mobile device based on the magnetic field value and the second magnetic field maps.
