Abstract
We present a system that can reconstruct 3D geometry from large, unorganized
collections of photographs such as those found by searching for a given city (e.g.,
Rome) on Internet photo-sharing sites. Our system is built on a set of new,
distributed computer vision algorithms for image matching and 3D reconstruction,
designed to maximize parallelism at each stage of the pipeline and to scale
gracefully with both the size of the problem and the amount of available
computation. Our experimental results demonstrate that it is now possible to
reconstruct city-scale image collections with more than a hundred thousand images
in less than a day.
