This paper describes an outdoor mobile robot navigation and localization system
based on visual features. We use a novel feature detector operating on wide-angle images and create a database of image features for a large outdoor environment. Images are geo-tagged by their pose. Given an arbitrary view we use algorithms inspired by "Video Google" to extract scenes from the database that overlap the current view and from which we can estimate our current pose in the environment or detect loop closures.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
