A model-based visual navigation system developed at the University of Oulu is described. The system consists of a hierarchy of processing levels where low level stages are data driven and the highest stage is model driven. With passive three-camera stereovision a sparse depth map of the scene is produced. Descriptions of important local scene structures are extracted using the properties of edge segments and relations between neighboring segments. The nature of the environment and world constraints are exploited to support extraction of the description. Prior knowledge of the world is used for global path finding, aiding scene analysis and providing feedback information to close the control loop between planned and actual movements.
