• A 3D Reactive Collision Avoidance Algorithm for Underactuated Vehicles 

      Syre Wiig, Martin; Pettersen, Kristin Ytterstad; Krogstad, Thomas Røbekk (Chapter, 2018)
      This paper presents a 3D reactive collision avoidance algorithm for vehicles with underactuated dynamics. The underactuated states cannot be directly controlled, but are controlled indirectly by steering the direction of ...
    • Deep learning based keypoint rejection system for underwater visual ego-motion estimation 

      Leonardi, Marco; Fiori, Luca; Stahl, Annette (Peer reviewed; Journal article, 2020)
      Most visual odometry (VO) and visual simultaneous localization and mapping (VSLAM) systems rely heavily on robust keypoint detection and matching. With regards to images taken in the underwater environment, phenomena like ...
    • Integral Line-of-Sight Guidance of Underwater Vehicles Without Neutral Buoyancy 

      Caharija, Walter; Syre Wiig, Martin; Krogstad, Thomas Røbekk; Pettersen, Kristin Ytterstad (Journal article; Peer reviewed, 2016)
      This paper analyzes an integral line-of-sight guidance law applied to an underac-tuated underwater vehicle. The vehicle is rigorously modeled in 5 degrees of freedom usingphysical principles, and it is ...
