    • 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 ...

    • 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 ...

    • Superflow – an efficient processing framework for modern C++ 

      Smestad, Ragnar; Larsen, Martin Vonheim; Haavardsholm, Trym Vegard (2024-04-08)
      This report describes Superflow, a generic data processing framework written in C++. Superflow is made for creating and running flexible processing graphs, where the nodes are individual processing stages, and the edges ...

    • Viewshed algorithms for strategic positioning of vehicles 

      Larsen, Martin Vonheim (2015-10-30)
      An important aspect of simulation and autonomous planning of military operations is to find good and realistic posititions for observation and attack. Essential to this is the ability to identify the set of positions ...

    • Warpath ASV – situational awareness for autonomous surface vessels 

      Larsen, Martin Vonheim; Smestad, Ragnar; Haavardsholm, Trym Vegard (2024-10-31)
      In order to operate in a complex and unpredictable environment, autonomous surface vessels (ASVs) must be able to generate their own situational awareness (SA). Here we present Warpath ASV, a ASV-tailored specialization ...
