Adaptation and Learning for Image Based NavigationAuthors: Supreeth Achar, C V Jawahar Conference: Proc. of the IEEE Sixth Indian Conference on Computer Vision, Graphics and Image Processing (ICVGIP 2008),pp. 103-110,Dec 16-19 2008, Bhubaneswar, India. Date: 2009-01-22 Report no: IIIT/TR/2009/16 AbstractImage based methods are a new approach for solving problems in mobile robotics. Instead of building a metric (3D) model of the environment, these methods work directly in the sensor (image) space. The environment is represented as a topological graph in which each node contains an image taken at some pose in the workspace, and edges connect poses between which a simple path exists. This type of representation is highly scalable and is also well suited to handle the data association problems that effect metric model based methods. In this paper, we present an efficient, adaptive method for qualitative localization using content based image retrieval techniques. In addition, we demonstrate an algorithm which can convert this topological graph into a metric model of the environment by incorporating information about loop closures.
