AR city representation system based on map recognition using topological information

Abstract

This paper presents a system for overlaying 3D GIS data information such as 3D buildings onto a 2D physical urban map. We propose a map recognition framework by analysis of distribution of local intersections in order to recognize the area of the physical map from a whole map. The retrieval of the geographical area described by the physical map is based on a hashing scheme, which is called LLAH. In the results, we will show some applications augmenting additional information on the map. © 2009 Springer Berlin Heidelberg.
