  • Klinger, Tobias; Rottensteiner, Franz; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    Many tracking systems rely on independent single frame detections that are handled as observations in a recursive estimation framework. If these observations are imprecise the generated trajectory is prone to be updated ...
  • Reich, Martin; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    In this paper we present a new global image orientation approach for a set of multiple overlapping images with given homologous point tuples which is based on a two-step procedure. The approach is independent on initial ...
  • Schmidt, Alena; Rottensteiner, Franz; Sörgel, Uwe; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2015)
    In this paper we propose a new method for the automatic extraction of tidal channels in digital terrain models (DTM) using a sampling approach based on marked point processes. In our model, the tidal channel system is ...
  • Alrajhi, M.N.; Jacobsen, Karsten; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2013)
    The General Directorate of Surveying and Mapping (GDSM), under the Ministry of Municipal and Rural Affairs (MOMRA) is responsible for the production and dissemination of accurate geospatial data for all the metropolitan ...
  • Ok, A.O.; Wegner, Jan Dirk; Heipke, Christian; Rottensteiner, Franz; Sörgel, Uwe; Toprak, V. (Hannover : International Society for Photogrammetry and Remote Sensing, 2010)
    In this study, we developed a new pair-wise relation based approach for the matching of line features from stereo aerial images. To solve the final matching inconsistencies, we propose an iterative pair based post-processing ...
  • Kersten, Tobias; Ren, Le; Schön, Steffen (Noordwijk, The Netherlands : Esa ESTEC, 2018)
    Efficient and economic guidance of inland vessels relies on a continuous, available, reliable and precise GNSS navigation solution. Hence, below other side effects, this is especially critical when passing beneath bridges ...

  • Niemeyer, Joachim; Rottensteiner, Franz; Sörgel, Uwe; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2015)
    In this investigation, we address the task of airborne LiDAR point cloud labelling for urban areas by presenting a contextual classification methodology based on a Conditional Random Field (CRF). A two-stage CRF is set up: ...
  • Kersten, Tobias; Ren, Le; Schön, Steffen (Bonn : DGON, 2018)
    This paper describes a concept to obtain a continuous navigation and position solution of inland vessels based on a multi-GNSS antenna system. Also known as, “Virtual Receiver” we utilize this approach as an alternative ...

  • Jacobsen, Karsten; Topan, H. (Hannover : International Society for Photogrammetry and Remote Sensing, 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 ...
  • Alkhatib, Hamza; Kutterer, Hansjörg (Berlin : Walter de Gruyter, 2013-05-18)
    In many cases, the uncertainty of output quantities may be computed by assuming that the distribution represented by the result of measurement and its associated standard uncertainty is a Gaussian. This assumption may be ...
  • Schmidt, Alena; Rottensteiner, Franz; Sörgel, Uwe; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    We propose a method for the automatic extraction of fluvial networks in lidar data with the aim to obtain a connected network represented by the fluvial channels' skeleton. For that purpose we develop a two-step approach. ...
  • Fernández, Hernan; Venkatachalam, Sriram; Schimmels, Stefan; Budzik, Mariusz; Oumeraci, Hocine (Reston : American Society of Civil Engineers (ASCE), 2014)
    A proper design of offshore and coastal structures requires further knowledge about extreme wave events. Such waves are highly nonlinear and may occur unexpectedly due to diverse reasons. One of these reasons is wave-wave ...
  • Kersten, Tobias; Schön, Steffen (Berlin Heidelberg : Springer, 2017)
    Precise navigation and geodetic coordinate determination rely on accurate GNSS signal reception. Thus, the receiver antenna properties play a crucial role in the GNSS error budget. For carrier phase observations, a spherical ...
  • Feuerhake, Udo; Brenner, Claus; Sester, Monika (Basel : MDPI AG, 2015)
    Tracking moving objects is both challenging and important for a large variety of applications. Different technologies based on the global positioning system (GPS) and video or radio data are used to obtain the trajectories ...
  • Zorndt, Anna C.; Goseberg, Nils; Schlurmann, Torsten (Reston : American Society of Civil Engineers (ASCE), 2014)
    The hydrodynamics of estuaries are forced by the tides from the open sea and the river runoff from the catchment area. The hinterland is often low-lying and densely populated and must therefore be protected by dikes. ...
  • Chen, Lin; Rottensteiner, Franz; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    This paper presents a new and fast binary descriptor for image matching learned from Haar features. The training uses AdaBoost; the weak learner is built on response function for Haar features, instead of histogram-type ...
  • Sriram, V.; Didenkulova, I.; Schimmels, Stefan; Sergeeva, A.; Goseberg, Nils (Reston : American Society of Civil Engineers (ASCE), 2014)
    This paper discusses the possibility to study propagation, shoaling and run-up of these waves over a slope in a 300-meter long large wave flume (GWK), Hannover. For this purpose long bell-shaped solitary waves (elongated ...
  • Goseberg, Nils; Schlurmann, Torsten (Reston : American Society of Civil Engineers (ASCE), 2014)
    This paper presents an experimental investigation that focuses on some predominant flow features that arise around surface mounted vertical obstacles which are exposed to a transient flow. The flow under investigation is ...
