Abstract
Pedestrian dead reckoning (PDR) based on inertial sensing
alone does not provide absolute user location relative to
the environment. Moreover, accuracy of the PDR position
estimates degrades as a function of time due to the
inaccuracies in the raw sensor data. Therefore, a key for
successful and cost-effective indoor positioning is to
find a way to provide occasional location fixes to assist
the PDR. We present a novel way to use a magnetometer to
detect and identify artificially created magnetic
anomalies that can be interpreted as location fixes.
Since inertial measurement units (IMUs) commonly include
a built-in magnetometer for heading estimation, the
proposed method does not require any additional hardware
to be carried by the user. The objective of the paper is
to introduce the aforementioned approach in more detail
and to evaluate it with a prototype and a positioning
trial. (15 refs.)
