Photogrammetry, or more strictly speaking
stereophotogrammetry, is the derivation of 3D
information on points, lines and areas on
objects or terrain from photographic image
sequences. It is a non-contact technique which
creates virtual reality 3D scenes with real-life
textured models. Created data can be used for
measurements and interpretation of objects by
providing precise 3D point coordinates and
other geometric and semantic object
information such as size and volume
information. It can be used in digital, graphical
and orthophoto forms as maps, charts and
overlays, but also 3D-printed to create precise
copies of the original objects.
