  • Dini, G.R.; Jacobsen, Karsten; Rottensteiner, Franz; Al Rajhi, M.; Heipke, Christian (Göttingen : Copernicus GmbH, 2012)
    In this paper, a workflow is proposed to detect 3D building changes in urban and sub-urban areas using high-resolution stereoscopic satellite images of different epochs and a GIS database. Semi-global matching (SGM) is ...
  • Kosov, Sergej; Rottensteiner, Franz; Heipke, Christian; Leitloff, Jens; Hinz, Stefan (Göttingen : Copernicus GmbH, 2012)
    The precise classification and reconstruction of crossroads from multiple aerial images is a challenging problem in remote sensing. We apply the Markov Random Fields (MRF) approach to this problem, a probabilistic model ...
  • Feng, Yu; Schlichting, Alexander; Brenner, Claus (Göttingen : Copernicus GmbH, 2016)
    Accurate positioning of vehicles plays an important role in autonomous driving. In our previous research on landmark-based positioning, poles were extracted both from reference data and online sensor data, which were then ...
  • 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 ...
  • Klinger, Tobias; Rottensteiner, Franz; Heipke, Christian (Göttingen : Copernicus GmbH, 2016)
    Online multi-person tracking in image sequences is commonly guided by recursive filters, whose predictive models define the expected positions of future states. When a predictive model deviates too much from the true motion ...
  • 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 ...
  • Huang, Hai; Sester, Monika (Göttingen : Copernicus GmbH, 2011)
    This work presents a combined bottom-up and top-down approach to extraction and refinement of building footprints from airborne LIDAR data. Building footprints are interesting for many applications in urban planning. The ...
  • 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 ...
  • Ok, A.O.; Wegner, J.D.; Heipke, Christian; Rottensteiner, Franz; Sörgel, Uwe; Toprak, V. (London : International Society for Photogrammetry and Remote Sensing, 2010)
    In this study, a new methodology for the reconstruction of line features from multispectral stereo aerial images is presented. We take full advantage of the existing multispectral information in aerial images all over the ...
  • 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 ...
  • Haberlandt, Uwe; Ebner Von Eschenbach, A.-D.; Buchwald, I. (Göttingen : Copernicus GmbH, 2008)
    For derived flood frequency analysis based on hydrological modelling long continuous precipitation time series with high temporal resolution are needed. Often, the observation network with recording rainfall gauges is poor, ...
  • 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 ...
  • Pohle, Ina; Niebisch, Michael; Zha, Tingting; Schümberg, Sabine; Müller, Hannes; Mauer, Thomas; Hinz, Christoph (München : European Geosciences Union, 2017)
    Rainfall variability within a storm is of major importance for fast hydrological processes, e.g. surface runoff, erosion and solute dissipation from surface soils. To investigate and simulate the impacts of within-storm ...
  • Albert, Lena; Rottensteiner, Franz; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    This paper proposes a two-layer Conditional Random Field model for simultaneous classification of land cover and land use. Both classification tasks are integrated into a unified graphical model, which is reasonable due ...
  • Passini, Ricardo; Jacobsen, Karsten (London : International Society for Photogrammetry and Remote Sensing, 2004)
    The generation of digital Orthophotos now days can be done with aerial, but also very high resolution space imagery. For a real competition the geometric and radiometric quality has to be on the same level. Different ...
  • Hofmann, Sabine; Brenner, Claus (Göttingen : Copernicus GmbH, 2016)
    Mobile mapping data is widely used in various applications, what makes it especially important for data users to get a statistically verified quality statement on the geometric accuracy of the acquired point clouds or its ...
  • Ok, A.O.; Wegner, Jan Dirk; Heipke, Christian; Rottensteiner, Franz; Sörgel, Uwe; Toprak, V. (Göttingen : Copernicus GmbH, 2011)
    In this study, a new reconstruction approach is proposed for the line segments that are nearly-aligned(<= 10 degrees) with the epipolar line. The method manipulates the redundancy inherent in line pair-relations to generate ...
  • Kersten, Tobias; Schön, Steffen (München : European Geosciences Union, 2015)
    Precise Point Positioning (PPP) is used in a broad variety of applications to determine very economically high precision parameters for positioning, navigation and timing. In comparison to traditional differential approaches, ...
  • Jacobsen, Karsten; Passini, R. (Göttingen : Copernicus GmbH, 2010)
    Digital elevation models (DEM) are of fundamental importance for remote sensing. With a DEM the three-dimensional positioning, requiring a stereo model can be reduced to a two-dimensional solution just based on a single ...
