This paper proposes a fully automated 3D reconstruction
and visualization system for architectural scenes (interiors
and exteriors). The reconstruction of indoor environments
from photographs is particularly challenging due
to texture-poor planar surfaces such as uniformly-painted
walls. Our system first uses structure-from-motion, multiview
stereo, and a stereo algorithm specifically designed for
Manhattan-world scenes (scenes consisting predominantly
of piece-wise planar surfaces with dominant directions) to
calibrate the cameras and to recover initial 3D geometry in
the form of oriented points and depth maps. Next, the initial
geometry is fused into a 3D model with a novel depth-map
integration algorithm that, again, makes use of Manhattanworld
assumptions and produces simplified 3D models. Finally,
the system enables the exploration of reconstructed
environments with an interactive, image-based 3D viewer.
We demonstrate results on several challenging datasets, inclu...
