  • Kentsch, Sarah; Cabezas, Mariano; Tomhave, Luca; Groß, Jens; Burkhard, Benjamin; Caceres, Maximo Larry Lopez; Waki, Katsushi; Diez, Yago (Basel : MDPI AG, 2021)
    Invasive blueberry species endanger the sensitive environment of wetlands and protection laws call for management measures. Therefore, methods are needed to identify blueberry bushes, locate them, and characterise their ...
  • Unger, Jakob; Rottensteiner, Franz; Heipke, Christian (London : International Society for Photogrammetry and Remote Sensing, 2017)
    This paper addresses the integration of a building model into the pose estimation of image sequences. Images are captured by an Unmanned Aerial System (UAS) equipped with a camera flying in between buildings. Two approaches ...
  • Schrader, Thorsten; Bredemeyer, Jochen; Mihalachi, Marius; Ulm, David; Kleine-Ostmann, Thomas; Stupperich, Christoph; Sandmann, Sergei; Garbe, Heyno (Göttingen : Copernicus GmbH, 2019)
    In this paper, we describe measurement results of the signal-in-space of very high frequency (VHF) omnidirectional range (VOR) facilities. In aviation VOR are used to display the current course of the aircraft in the ...
  • Kral, Stephan T.; Reuder, Joachim; Vihma, Timo; Suomi, Irene; O'Connor, Ewan; Kouznetsov, Rostislav; Wrenger, Burkhard; Rautenberg, Alexander; Urbancic, Gabin; Jonassen, Marius O.; Båserud, Line; Maronga, Björn; Mayer, Stephanie; Lorenz, Torge; Holtslag, Albert A.M.; Steeneveld, Gert-Jan; Seidl, Andrew; Müller, Martin; Lindenberg, Christian; Langohr, Carsten; Voss, Hendrik; Bange, Jens; Hundhausen, Marie; Hilsheimer, Philipp; Schygulla, Markus (Basel : MDPI AG, 2018)
    The aim of the research project "Innovative Strategies for Observations in the Arctic Atmospheric Boundary Layer (ISOBAR)" is to substantially increase the understanding of the stable atmospheric boundary layer (SBL) through ...
  • Unger, Jakob; Rottensteiner, Franz; Heipke, Christian (Göttingen : Copernicus GmbH, 2016)
    A hybrid bundle adjustment is presented that allows for the integration of a generalised building model into the pose estimation of image sequences. These images are captured by an Unmanned Aerial System (UAS) equipped ...
  • Cefalu, A.; Haala, N.; Schmohl, S.; Neumann, I.; Genz, T. (London : International Society for Photogrammetry and Remote Sensing, 2017)
    Photogrammetric data capture of complex 3D objects using UAV imagery has become commonplace. Software tools based on algorithms like Structure-from-Motion and multi-view stereo image matching enable the fully automatic ...
  • Reich, Martin; Unger, Jakob; Rottensteiner, Franz; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    Civil applications for small size unmanned aerial vehicles (UAV) have become quite important in recent years and so have accurate orientation and navigation of these devices in unknown terrain. In this work we focus on ...
  • Braam, Miranda; Beyrich, Frank; Bange, Jens; Platis, Andreas; Martin, Sabrina; Maronga, Björn; Moene, Arnold F. (Dordrecht : Springer Netherlands, 2016)
    We elaborate on the preliminary results presented in Beyrich et al. (in Boundary-Layer Meteorol 144:83–112, 2012), who compared the structure parameter of temperature (C2T) obtained with the unmanned meteorological mini ...
  • Sledz, A.; Unger, J.; Heipke, C. (London : International Society for Photogrammetry and Remote Sensing, 2018)
    This paper deals with two aspects of photogrammetric processing of thermal images: image quality and 3D reconstruction quality. The first aspect of the paper relates to the influence of day light on Thermal InfraRed (TIR) ...
  • Unger, Jakob; Reich, Martin; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    The use of small-size unmanned aerial vehicles (UAV) for civil applications in many different fields such as archaeology, disaster monitoring, aerial surveying or mapping has significantly increased in recent years. The ...
