• Closing the Loop with Graphical SLAM 

      Folkesson, John; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2007-08)
      The problem of simultaneous localization and mapping (SLAM) is addressed using a graphical method. The main contributions are a computational complexity that scales well with the size of the environment, the elimination ...
    • Exploiting Distinguishable Image Features in Robotic Mapping and Localization 

      Jensfelt, Patric; Folkesson, John; Kragic, Danica; Christensen, Henrik I. (Georgia Institute of TechnologySpringer Verlag, 2006-03)
      Simultaneous localization and mapping (SLAM) is an important research area in robotics. Lately, systems that use a single bearing-only sensors have received significant attention and the use of visual sensors have been ...
    • Graphical SLAM for Outdoor Applications 

      Folkesson, John; Christensen, Henrik I. (Georgia Institute of TechnologyJohn Wiley & Sons, 2007-02)
      Application of SLAM outdoors is challenged by complexity, handling of non-linearities and flexible integration of a diverse set of features. A graphical approach to SLAM is introduced that enables flexible data-association. ...
    • The M-Space Feature Representation for SLAM 

      Folkesson, John; Jensfelt, Patric; Christensen, Henrik I. (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2007-10)
      In this paper, a new feature representation for simultaneous localization and mapping (SLAM) is discussed. The representation addresses feature symmetries and constraints explicitly to make the basic model numerically ...
    • SIFT Based Graphical SLAM on a Packbot 

      Folkesson, John; Christensen, Henrik I. (Georgia Institute of TechnologySpringer Verlag, 2008-03)
      We present an implementation of Simultaneous Localization and Mapping (SLAM) that uses infrared (IR) camera images collected at 10 Hz from a Packbot robot. The Packbot has a number of challenging characteristics with ...
