This research attacks the problem of modeling large
outdoor structures from a combination of range and image measurements.
This technology is being applied for the reconstruction of the Beauvais
Cathedral in France. A powerpoint presentation of the system can be
found here. This research is based
on Ioannis Stamos' PhD thesis. The volumetric method used is an extension
of Michael Reed's 3D modeler. Relevant publications can be found here.

Example: 3-D Outdoor modeling, with photometry, for buildings
on Columbia Campus. Dense range scans are segmented and registered, and
a 3-D solid model is created by volumetric sweep intersection. Texture
mapping is then automatically applied to create a geometric and photometric
correct model.
Guggenheim Museum. Two range scans are integrated to create a 3-D model which is then texture mapped.
Flatiron Building, NYC. Two range scans are integrated
to create a 3-D model which is then texture mapped.
