A set of image understanding (IU) modules is being developed
for performing several geometric site modeling tasks,
including initial model acquisition, model extension,
model-to-image registration and site model refinement.
This paper describes how the UMass system would
acquire an initial site model. IU algorithms have been
developed to hypothesize potential building roofs in an
image, automatically locate supporting geometric evidence in
other images, and determine the precise shape and position of
the new buildings via multi-image triangulation. This process
is demonstrated on a subset of images from the
RADIUS Model Board 1 data set.
