Title: Topological mapping, localization and navigation using image collections

Authors: Friedrich Fraundorfer, Christopher Engels, and David Nister

Abstract:

In this paper we present a highly scalable vision based localization and mapping method using image collections. A topological world representation is created online during robot exploration by adding images to a database and maintaining a link graph. An efficient image matching scheme allows real-time mapping and global localization. The compact image representation allows us to create image collections containing millions of images, which enables mapping of very
large environments. A path planning method using graph search is proposed and local geometric information is used to navigate in the topological map. Experiments show the good performance
of the image matching for global localization and demonstrate path planning and navigation.
