ABSTRACT
3D photography refers to the process of reconstructing 3D models
from various input sources, including digital images and laser range scans.
The goal of our software project is to advance the state-of-the-art in the nascent
field of 3D photography. We strive to make it possible to easily and accurately
import 3D models from scanned scene data. We will describe our ongoing work
in producing an integrated software system that performs automated photorealistic
reconstruction of real large-scale
environments. The input to this system is a sequence of range scans and camera
images of a scene we wish to reconstruct. The output is a complete photorealistic
model of the scene. Our objective is to make this process computationally efficient,
semi-automatic with minimal human interaction, and to provide models of high
geometric and photometric quality. Our efforts
towards this goal include advances in 2D-3D registration, 3D-3D registration,
mesh generation, mesh simplification, and implementation of multi-view geometry
for camera motion recovery. Reconstructed models of Shepard Hall,
the Great Hall, and Grand Central Terminal will be shown.
