MAP MODIFICATION USING GROUND-TRUTH MEASUREMENTS

摘要

Disclosed is a method for receiving a conceptual map of a navigable area, the conceptual map including two or more topological elements being related to one another in the conceptual map by a first set of dimensions; applying one or more ground truth measurements or topological constraints to the first set of dimensions of the conceptual map to provide a modified map having corrected dimensions; and mapping an estimated location of the mobile station to the modified map.
