Photogrammetrische Punktbestimmung bei der Überwachung von Staumauern

The paper discusses the use of modern methods of terrestrial photogrammetry as an alternative or supplement to conventional surveying methods for the repeated inspection of dams. Photogrammetry is a very efficient technique for measuring deformations on dams especially when a large number of points needs to be measured regularly. Photogrammetric 3-D point determination was carried out on the Luzzone dam in the Valle di Blenio. The photographs were taken with a ditigal high-resolution Kodak DCS200 still video camera and a Wild P31 metric photographic camera. The results of the point determination are presented and compared with measurements taken using a theodolite and a Mekometer ME500 high-precision distance measuring apparatus. -English summary
