  • DEM generation with short base length pleiades triplet 
    Jacobsen, Karsten; Topan, H. (Göttingen : Copernicus GmbH, 2015)
    An image triplet of Pleiades images covering the area of Zonguldak, Turkey has been investigated. The height to base relation of the first to the last image is just 1:4.5 and for the first and the second image 1:9. This ...
  • Detection and 3D modelling of vehicles from terrestrial stereo image pairs 
    Coenen, Max; Rottensteiner, Franz; Heipke, Christian (Göttingen : Copernicus GmbH, 2017)
    The detection and pose estimation of vehicles plays an important role for automated and autonomous moving objects e.g. in autonomous driving environments. We tackle that problem on the basis of street level stereo images, ...
  • Development of large area covering height model 
    Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2014)
    Height information is a basic part of topographic mapping. Only in special areas frequent update of height models is required, usually the update cycle is quite lower as for horizontal map information. Some height models ...
  • Global bundle adjustment with variable orientation point distance for precise mars express orbit reconstruction 
    Bostelmann, Jonas; Heipke, Christian (Katlenburg-Lindau : Copernicus Publications, 2016)
    The photogrammetric bundle adjustment of line scanner image data requires a precise description of the time-dependent image orientation. For this task exterior orientation parameters of discrete points are used to model ...
