Kurzfassung in Englisch:

We present a system that applies a custom-built pan-tilt-zoom camera
for laser-pointer tracking in arbitrary real environments. Once
placed in a building environment, it carries out a fully automatic
self-registration, registrations of projectors, and sampling of surface
parameters, such as geometry and reflectivity. After these steps,
it can be used for tracking a laser spot on the surface as well as
an LED marker in 3D space, using inter-playing fisheye context
and controllable detail cameras. The captured surface information
can be used for masking out areas that are critical to laser-pointer
tracking, and for guiding geometric and radiometric image correction
techniques that enable a projector-based augmentation on arbitrary
surfaces. We describe a distributed software framework that
couples laser-pointer tracking for interaction, projector-based AR
as well as video see-through AR for visualizations with the domain
specific functionality of existing desktop tools for architectural
planning, simulation and building surveying.
