Guest talk by Mr. Henning Deeken

We are happy to announce an invited talk by Mr. Henning Deeken on his group’s work in semantic mapping.

• Date: 06.10.2014 (Monday)
• Time: 16:00
• Room C-118

Mr. Deeken, is studying Cognitive Science at the University of Osnabrück. The talk will address both the construction of semantic maps using GIS-type databases and the subsequent usage of the map in robot navigation. Being interested in semantic mapping and the design of multi-purpose semantic mapping architectures, Mr. Deeken is currently working on his master thesis on these topics under the supervision of Prof. Dr. Joachim Hertzberg at the Knowledge Based Systems Lab.
 
Abstract:
“Executing high-level tasks in a fetch-delivery-scenario requires a robot to reason about what the desired object is and where it is located. At best, the underlying map to plan and execute such tasks allows for a close linkage of geometric and semantic information and efficient look ups. Geographic Information Systems combine relational and geometric data in one database and can serve as powerful backends for semantic mapping, because of their in-built ability to handle spatial queries. In this paper, we present a GIS-based approach to semantic mapping that allows semantic labels to be integrated closely with geometric environment maps. We show that our semantic map is suited to store and maintain information that supports complex task planning, as well as ther tasks. As an example, we show how robot navigation can be improved by including semantic information.”
