  • Endoscopic fringe projection for in-situ inspection of a sheet-bulk metal forming process 
    Matthias, Steffen; Kästner, Markus; Reithmeier, Eduard (Bellingham, Wash. : SPIE, 2015)
    Sheet-bulk metal forming is a new production process capable of performing deep-drawing and massive forming steps in a single operation. However, due to the high forming forces of the forming process, continuous process ...
  • Fast in-situ tool inspection based on inverse fringe projection and compact sensor heads 
    Matthias, Steffen; Kästner, Markus; Reithmeier, Eduard (Bellingham, Wash. : SPIE, 2016)
    Inspection of machine elements is an important task in production processes in order to ensure the quality of produced parts and to gather feedback for the continuous improvement process. A new measuring system is presented, ...
  • Metal forming tool monitoring based on a 3D measuring endoscope using CAD assisted registration 
    Hinz, Lennart; Kästner, Markus; Reithmeier, Eduard (Basel : MDPI AG, 2019)
    In order to provide timely, reliable, and comprehensive data for the maintenance of highly stressed geometries in sheet-bulk metal forming tools, this article features a possible setup by combining a 3D measuring endoscope ...
  • On the development of a low-cost rigid borescopic fringe projection system 
    Schlobohm, Jochen; Pösch, Andreas; Kästner, Markus; Reithmeier, Eduard (Bellingham, Wash. : SPIE, 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 ...
  • Panorama imaging for image-to-physical registration of narrow drill holes inside spongy bones 
    Bergmeier, Jan; Fast, Jacob Friedemann; Ortmaier, Tobias; Kahrs, Lüder Alexander (Bellingham, Wash. : SPIE, 2017)
    Image-to-physical registration based on volumetric data like computed tomography on the one side and intraoperative endoscopic images on the other side is an important method for various surgical applications. In this ...
  • A raspberry pi based portable endoscopic 3D measurement system 
    Schlobohm, Jochen; Pösch, Andreas; Reithmeier, Eduard (Basel : MDPI AG, 2016)
    Geometry measurements are very important to monitor a machine part’s health and performance. Optical measurement system have several advantages for the acquisition of a parts geometry: measurement speed, precision, point ...
  • Single image geometry inspection using inverse endoscopic fringe projection 
    Matthias, Steffen; Ohrt, Christoph; Pösch, Andreas; Kästner, Markus; Reithmeier, Eduard (Budapest : International Measurement Confederation (IMEKO), 2015)
    Fringe projection is an important technology for the measurement of free form elements in several application fields. It can be applied to measure geometry elements smaller than one millimeter. In combination with deviation ...
