MOBILE DEVICE OF ESTIMATING A LOCATION USING A PARTICLE FILTER GENERATED BASED ON A 3D MAGNETIC FIELD MAP AND METHOD THEREOF

摘要

Disclosed is a mobile terminal for estimating a location using a particle filter generated based on a 3D magnetic field map. The mobile terminal according to one embodiment of the present invention includes: a magnetic field sensor which measures a magnetic field value in the location of the mobile terminal; a memory which stores first magnetic field maps corresponding to N heights; a magnetic field map drawing unit which draws second magnetic field maps corresponding to M heights, wherein M is larger than N; and a location determining unit which determines the location of the mobile terminal based on the magnetic field value and the second magnetic field maps.
