\section{System Overview}
|
|
|
|
The navigation system is based on our previous works, primarily on the approach presented in \cite{ebner-15}.
|
|
For this, we have been awarded the best overall paper award at IPIN 2015 in Banff, Canada.
|
|
Since then, we extended our approach by prior navigation knowledge using realistic human walking paths \cite{} and smoothing methods \cite{}.
|
|
Additionally, a self-developed map editor allows for creating advanced 3D maps and realistically shaped stairs.
|
|
Compared to many other systems, we avoid any time-consuming fingerprinting and calibration processes and are able to start with a uniform distribution over the whole building.
|
|
All calculations are computed in real time on a commercial smartphone, in most of our examples this is the Motorola Nexus 6.
|
|
The system is implemented in C++ using the Qt framework and OpenCL.
|
|
|
|
An overview of all involved components and the sensor fusion procedure can be seen in fig. \ref{}.
|
|
Here, the smartphone provides all necessary measurements and no additional device is needed.
|
|
|
|
|
|
This ensures sensor is defect or is not provided by the smartphone itself

\section{Prior Arrangements}
|
|
System setup is very easily and no fingerprinting is required.
