Method for determing a position of a tracking device

摘要

The invention relates to a method for determining an indoor position of a tracking device. The method uses a Heuristic Drift Elimination (HDE) algorithm which is modified by using additional knowledge about the indoor environment. The additional knowledge is in the form of so-called "local dominant direction domains" which are automatically extracted from floorplans. Using local dominant direction domain allows improving the performance of the HDE algorithm where additional knowledge is available, while reverting to the standard HDE algorithm where it is not.
