    • Achieving Sub-Pixel Platform Accuracy With Pan-Tilt-Zoom Cameras in Uncertain Times 

      Larsen, Martin Vonheim; Mathiassen, Kim (2024-11-28)
      In this paper, we present a novel method for selfcalibrating a pan-tilt-zoom (PTZ) camera system model, specifically suited for long-range multi-target tracking with maneuvering low-cost PTZ cameras. Traditionally, such ...

    • BASE: Probably a Better Approach to Visual Multi-Object Tracking 

      Larsen, Martin Vonheim; Rolfsjord, Sigmund Johannes Ljosvoll; Gusland, Daniel; Ahlberg, Jörgen; Mathiassen, Kim (2024)
      The field of visual object tracking is dominated by methods that combine simple tracking algorithms and ad hoc schemes. Probabilistic tracking algorithms, which are leading in other fields, are surprisingly absent from the ...

    • Demonstrating Interoperability Between Unmanned Ground Systems and Command and Control Systems 

      Mathiassen, Kim; Schneider, Frank; Bounker, Paul; Tiderko, Alexander; De Cubber, Geert; Baksaas, Magnus; Glowka, Jakub; Kozik, Rafal; Nussbaumer, Thomas; Röning, Juha; Pellenz, Johannes; Volk, Andre (2021-05-25)
      This paper describes the research and experiment efforts of the NATO STO group IST-149-RTG capability concept demonstrator for interoperability within unmanned ground systems and C2 and the NAAG team of experts on UGV. ...

    • Evaluation of Two Path Following Controllers for an Ackermann Off-road Vehicle in Winter and Summer Conditions 

      Baksaas, Magnus; Olsen, Lars Erik; Mathiassen, Kim (2021-04-02)
      Off-road driving can be a challenging task with rapid changes in the driving conditions, terrain and vehicle behavior. For off-road autonomous vehicles, it is important to be robust to these changes, and parts of this ...

    • How extending the kinematic model affects path following in off-road terrain for differential drive UGVs 

      Tisland, Andreas; Baksaas, Magnus; Mathiassen, Kim (2022-05-31)
      Traversal in off-road conditions for Unmanned Ground Vehicles is highly relevant for defence applications, with an increasing amount of research being put into the field. A central part of the autonomous traversal is path ...

    • In-operation calibration of clock-bias and intrinsic parameters for pan-tilt-zoom cameras based on keypoint tracking 

      Larsen, Martin Vonheim; Haavardsholm, Trym Vegard; Mathiassen, Kim (2020-09-20)
      We propose a method for jointly estimating intrinsic calibration and internal clock synchronisation for a pantilt- zoom (PTZ) camera using only data that can be acquired in the field during normal operation. Results show ...

    • LandX20 Experiment Report – experiment for future land warfare capabilities with focus on increased situational awareness and unmanned systems 

      Mathiassen, Kim; Baksaas, Magnus; Dyrdal Idar; Eikanger, Brage Gerdsønn; Gulbrandsen, Fredrik; Gusland, Daniel; Larsen, Martin Vonheim; Mentzoni, Eilert; Minos-Stensrud, Mathias; Moen, Jonas; Nilssen, Eivind Bergh; Nummedal, Olav Rune; Nygaard, Tønnes; Rolfsjord, Sigmund; Simonsen, Aleksander; Thoresen, Marius; Bakstad, Lorns Harald; Bentsen, Dan Helge; Eggesbø, Christian; Grimstvedt, Eirik Skjelbreid; Haavardsholm, Trym Vegard; Halsør, Marius; Hoelsæter, Øistein; Kolden, David; Krogstad, Thomas Røbekk; Macdonald, Robert Helseth; Nielsen, Niels Hygum; Nonsvik, Guri; Ruud, Else-Line Malene; Seehuus, Rikke Amilde; Wiig, Martin Syre; Østevold, Einar (2022-03-21)
      LandX20 was a collaborative experiment and demonstration where four research projects from the Norwegian Defence Research Establishment (FFI) participated. The goal of the experiment was two-fold. The first goal was to ...

    • LandX23 - target acquisition and engagement 

      Bentsen, Dan Helge; Asak, Ole Martin; Bakstad, Lorns Harald; Nilssen, Eivind Bergh; Bjerke, Sven; Dalsjø, Per; Dybwad, Katrine Mygland; Eiksund, Oddmar; Folke-Olsen, Sander; Fyhn, Sondre Holm; Haavardsholm, Trym Vegard; Hanevold, Morten; Hellemo, Håkon; Horn, Christian; Imenes, Anders; Kolden, David; Larsen, Martin Vonheim; Mathiassen, Kim; Macdonald, Robert H.; Minos-Stensrud, Mathias; Nielsen, Niels-Hygum; Nielsen, Martin Normann; Nummedal, Olav Rune; Olsen, Lars Erik; Paulsmoen, Morten; Rosvold, Gard Inge; Sele, Marta Lill; Skaar, Sindre Løining; Simonsen, Aleksander Skjerlie; Spilling, Torjus; Stien, Håvard (2024-05-22)
      LandX is the Norwegian Defence Research Establishment’s (FFI’s) yearly two-week collaborative event focusing on experimental technologies in the land domain. LandX23 was its fourth edition. Over the years, the complexity ...

    • Making the Milrem Themis UGV ready for autonomous operations 

      Mathiassen, Kim; Baksaas, Magnus; Aas Græe, Sindre; Mentzoni, Eilert André; Nielsen, Niels Hygum (2021-04-12)
      The usage of Unmanned Ground Vehicles (UGVs) in defence application is increasing, and much research effort is put into the field. Also, many defence vehicle producers are developing UGV platforms. However, the autonomy ...

    • Path Planning for UGVs Based on Traversability Hybrid A*
