  • Automatic measurement of sewer man-holes in large scale aerial images 
    Pollak, Bernd; Jacobsen, Karsten ([Wechselnde Verlagsorte] : ISPRS, 2000)
    The geometric changes of the surface (subsidence and horizontal displacement) caused by coal mining can be determined by photogrammetry with a sufficient accuracy. As long time stable targets sewer manholes can be used. ...
  • A new straight line reconstruction methodology from multi-spectral stereo aerial images 
    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 ...
  • A stereo line matching technique for aerial images based on a pair-wise relation approach 
    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 ...
  • Supervised detection of bomb craters in historical aerial images using convolutional neural networks 
    Clermont, D.; Kruse, C.; Rottensteiner, F.; Heipke, C. (Göttingen : Copernicus, 2019)
    The aftermath of the air strikes during World War II is still present today. Numerous bombs dropped by planes did not explode, still exist in the ground and pose a considerable explosion hazard. Tracking down these duds ...
