Edgar-Philipp Stoffel, Bernhard Lorenz, Hans Jürgen Ohlbach:
Towards a Semantic Spatial Model for Pedestrian Indoor Navigation.
Abstract
This paper presents a graph-based spatial model which can
serve as a reference for guiding pedestrians inside buildings. We describe
a systematic approach to construct the model from geometric data. In
excess of the well-known topological relations, the model accounts for two
important aspects of pedestrian navigation: firstly, visibility within
spatial areas and, secondly, generating route descriptions. An algorithm
is proposed which partitions spatial regions according to visibility
criteria. It can handle simple polygons as encountered in floor plans. The
model is structured hierarchically - each of its elements corresponds to a
certain domain concept ('room', 'door', 'floor' etc.) and can be annotated
with meta information. This is useful for applications in which such
information have to be evaluated.
