Simultaneous Localization and Mapping by Using Earth's Magnetic Fields

摘要

Obtaining a motion data set from a plurality of mobile devices; Predicting a root model of an advanced route based on the motion data set; Linking the obtained EMF data set to a corresponding point of the root model to generate an EMF fingerprint for the advanced route; And determining the position of the root relative to each other based on at least one of the EMF fingerprint and the root model.
