Title: Site Model Acquisition under the UMass RADIUS Project
Authors: Robert T. Collins, Allen R. Hanson, and Edward M. Riseman

Abstract:
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.
