ABSTRACT
Augmented Reality (AR) [Azuma 1997], [Azuma
et al. 2000] is a visualisation technology for dis-
playing virtual models real time in real world loca-
tions, with building and construction as one of
the most promising application fields; cf. [Klinker
et al. 2001], [Woodward et al. 2007]. Recent devel-
opments in mobile processing units, camera qual-
ity, different sensors, wireless infrastructure and
tracking technology enable AR applications to
be implemented even in demanding mobile envi-
ronments, see e.g. [Pasman and Woodward 2003],
[Izkara et al. 2007], [Behzadan 2008].
