Terrestrial photogrammetry

Terrestrial photogrammetry

Terrestrial photogrammetry is based on the visual documentation of the object to be surveyed. We use this technique for the visual documentation of buildings and other terrestrial objects at close range.

Introduced about 140 years ago for documenting historic monuments and art treasures, this process is still used today for documentation purposes for the protection of historic monuments, as well as in architecture, design, preservation of evidence, visualisation and 3D modelling.

The advantage of the process lies in the fact that an up-to-date and complete image of the structures can be recorded. The detailed evaluation is carried out retrospectively, separated spatially and temporally from the image recorded.

The method of single image rectification, which is used to produce facade views as an image file quickly and inexpensively as well as a CAD drawing at a later stage, is suitable for simple, level and unstructured objects. Objects with complex spatial structures are recorded using the traditional method of stereoscopic evaluation.

For image acquisition we have medium size (6 cm x 6 cm) and large size (13 cm x 18 cm) photographic cartographic cameras as well as digital camera systems.

High-lying and inaccessible sections as well as roof surfaces can be recorded by drones/UAVs to complete the survey where necessary.
