Photogrammetric Measuring Methods

Synopsis: A programme from the series produced by the Federal Waterways Engineering and Research Institute;. Optical measuring methods applied the physical models of the BAW yield high quality and high quantity data. Using 2D particle tracking velocimetry, one camera records the velocity of the water surface. Using the 3D particle tracking velocimetry, three cameras are recording in three dimensions the water level and the surface velocity in the model at the same time. Three cameras also measure photogrammetrically the geometry and the changes of the river bed through the water during the ongoing experiment. Data are used in numerical models with which further dynamic analysis is performed.

Notes: Formerly known as Institut für den Wissenschaftlichen Film. IWF’s Infoteque contains details of over 8,900 films for use in university-level teaching and research. The collection is particularly strong in the areas of scientific and ethnographic films. The films are in German but many are also available with English commentaries. Programmes are available for sale on DVD, video or CD-ROM and some can be previewed free online. There is also an online Media Library of Cell Biology (http://www.iwf.de/IWF/Media/Cellbiology.htm) supplying digital media in various formats.
