Road Geometry Estimation for Urban Semantic Maps using Open Data

Complex robotic tasks require the use of knowledge that cannot be acquired with the sensor repertoire of a mobile, autonomous robot alone. For robots navigating in urban environments, geospatial open data repositories such as OpenStreetMap (OSM) provide a source for such knowledge. We propose the integration of a 3D metric environment representation with the semantic knowledge from such a database. The application we describe uses street network information from OSM to improve street geometry information determined from laser data. This approach is evaluated on a challenging data-set of the Munich inner city.     «
