``The AVENUE Automated Site Modeling Project: Geometry and Texture
Recovery of Scenes of Large Scale''

			       
			       Abstract

The AVENUE project's goal is to automate the site modeling process.
The main component of AVENUE is a system for photo-realistic 3D model
acquisition from the combination of range and image sensing. The input
is a sequence of unregistered range scans of the scene and a sequence
of unregistered 2-D photographs of the same scene. The output is a
true texture-mapped geometric model of the scene.  Segmentation
algorithms simplify the dense data-sets and provide stable features of
interest which can be used for registration purposes.  Solid modeling
provides geometrically correct 3-D models, which can be automatically
texture mapped from current or historic photographs.  The system is
comprehensive in that it addresses all phases of the modeling problem
with a particular emphasis on automating the entire process.  We
present results from scanning and modeling a variety of objects
ranging from buildings in New York City to the Cathedral of
Ste. Pierre in Beauvais, France. The system currently resides on a
mobile robot which will be used to model archaeological sites in
Egypt.
