Armin Grün (born April 27, 1944 in Bad Berneck, Germany) was since 1984 Professor and Head of the Chair of Photogrammetry at the Institute of Geodesy and Photogrammetry (IGP), Federal Institute of Technology (ETH) Zurich, Switzerland. Since 1 August 2009 he is retired and is now with the Institute of Historic Building Research and Conservation, ETH Zurich Faculty of Architecture. For a year he worked part-time as Principal Investigator for the Simulation Platform of the Singapore - ETH Centre for Global Environmental Sustainability (SEC) project Future Cities Laboratory (FCL).

Research[edit]

Armin Grün's group’s major scientific achievements include (in chronological order):

  • Studies to the processing of amateur photographs (including his PhD thesis “Reconstruction of rotation surfaces from single images”)
  • System calibration by self-calibration with additional parameters
  • Reliability studies and blunder detection in bundle systems
  • Algorithms for sequential estimation in bundle systems (on-line triangulation)
  • Geometrically constrained multi-image least squares image matching
  • CCD-camera based measurement systems in close-range photogrammetry (“videogrammetry”)
  • Development of the new concept of a Digital Photogrammetric Station with the first pilot system (DIPS1)
  • Digital ortho-image generation on general low-cost computers
  • PTV system for the measurement of flow structures
  • First practical test for the integration of GPS and (simulated) INS observations into a photogrammetric bundle block, including self-calibration
  • LSB-Snakes for line feature extraction
  • CyberCity Modeler for semi-automated 3D city modeling
  • 3D modeling and tracking of clouds from satellite and terrestrial imaging sensors
  • 3D modeling in Archaeology and Cultural/Natural Heritage (among those are the Nasca geoglyphs, Mount Everest, Ayers Rock, the reconstruction of the Great Buddha of Bamyian, etc.)
  • Implementation and testing of new sensor and trajectory models for aerial and satellite Linear Array cameras, including self-calibration, for calibration, geo-referencing, validation
  • Advanced image matching for DSM generation
  • 3D Least Squares Surface and Intensity matching
  • UAV photogrammetry

His group’s most recent major projects in 3D modeling of Cultural Heritage, based on photogrammetry, laser scanning and structured light, include: Nasca Lines/Geoglyphs, Adobe pyramids of Tucume, Machu Picchu, Pinchango Alto, petroglyphs of Chichictara (all Peru), Mount Everest, Ayers Rock (Australia), reconstruction of the two Great Buddhas of Bamiyan, pre-Columbian site of Xochicalco (Mexico), Maya site of Copan (Honduras), Bayon/Angkor Wat (Cambodia), Drapham Dzong (Bhutan), Weary Herakles (Antalya, Turkey), Khmer Head (Rietberg Museum), Zurich 1800 city model relief, Alfred Escher memorial, St. Gallen Globe (all Zurich), Pfyffer Relief (Lucerne).
