  • Schlobohm, Jochen; Li, Yinan; Pösch, Andreas; Langmann, Benjamin; Kästner, Markus; Reithmeier, Eduard (Amsterdam : Elsevier, 2014)
    The inspection of capital goods with complex geometries is a challenging task due to the limited maneuvering and measuring space available. We developed a set of optical measurement systems for the inline inspection of ...
  • Loftfield, N.; Kastner, M.; Reithmeier, E. (Bristol : Institute of Physics Publishing, 2018)
    Structured surfaces enhance the functionality of components. Well known is the influence of the surface structure on friction and wear behavior. Beyond this, structured surfaces are widely used for various purposes such ...
  • Schlobohm, Jochen; Pösch, Andreas; Kästner, Markus; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Examining the geometry of complex industrial free form objects, like a blade integrated disk (blisk) of a jet engine compressor, is currently subject to research. High measurement precision and speed are required and the ...
  • Hartmann, J.; Von Gösseln, I.; Schild, N.; Dorndorf, A.; Paffenholz, J.-A.; Neumann, I. (London : International Society for Photogrammetry and Remote Sensing, 2019)
    In recent years, the requirements in the industrial production of elongated objects, e.g., aircraft, have been increased. An essential aspect of the production process is the 3D object detection as well as the qualitative ...
  • Jacobsen, Karsten (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    Based on test blocks and standard production blocks Z/I Imaging DMCII-140, 230 and 250 as well as UltraCam Eagle images have been analyzed by bundle block adjustment with self calibration. By analysis of image coordinate ...
  • Grabowski, R.; Denkena, Berend; Köhler, Jens (Amsterdam : Elsevier, 2014)
    In order to optimize the cutting performance of end mills, the geometry of such cutters is optimized by toolmakers constantly. As a result of geometric changes, process forces can be reduced, i.e. by serrated end mills. ...
  • Jacobsen, Karsten; Neumann, K. (Göttingen : Copernicus GmbH, 2012)
    Z/I Imaging introduced with the DMC II 140, 230 and 250 digital aerial cameras with a very large format CCD for the panchromatic channel. The CCDs have with 140 / 230 / 250 mega pixel a size not available in photogrammetry ...
  • Hofmann, Sabine; Schulze, Malte Jan; Sester, Monika; Brenner, Claus (Göttingen : Copernicus GmbH, 2011)
    Driving autonomously requires highly accurate positioning. Therefore, alternative positioning systems to GPS are required especially to increase the accuracy, and to have a complementary data source in areas where GPS is ...
  • Jacobsen, Karsten; Topan, H.; Cam, A.; Özendi, M.; Oruç, M. (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    Pleiades images are distributed with 50cm ground sampling distance (GSD) even if the physical resolution for nadir images is just 70cm. By theory this should influence the effective GSD determined by means of point spread ...
  • Behrens, Bernd-Arno; Doege, E.; Krimm, R. (London : SAGE Publications Ltd., 2006)
    The production processes of sheet metal products with complex geometries often use transfer presses to obtain fully formed workpieces from a single machine. The job of adjusting a new multistage tool set increases with the ...
  • Gesing, Thorsten M.; Schowalter, Marco; Weidenthaler, Claudia; Murshed, M. Mangir; Nénert, Gwilherm; Mendive, Cecilia B.; Curti, Mariano; Rosenauer, Andreas; Buhl, Josef-Christian; Schneider, Hartmut; Fischer, Reinhard X. (Cambridge : Royal Society of Chemistry, 2012)
    We report on strontium doped dibismuth-nonaoxoaluminate(III) produced at 1023 K. Partial substitution of bismuth by strontium in the structure yields oxygen vacancies for charge balance. Introducing oxygen vacancies ...
  • Wippo, V.; Winter, Y.; Jaeschke, P.; Suttmann, O.; Overmeyer, L. (Amsterdam : Elsevier B.V., 2016)
    Presently, fiber reinforced materials are used for many industrial applications. Laser transmission welding (LTW) is a suitable method to join these materials. For multiple thermoplastics, the weld seam quality is affected ...
  • Kerpen, Nils B.; Schlurmann, Torsten (Reston : American Society of Civil Engineers, 2012)
    Hydraulic model tests at a scale of 1:10 are carried out in a 40 m x 25 m wave basin with a state-of-the-art 3D wave generator in order to collect wave overtopping data at vertical walls and dykes with topped vertical ...
