Photogrammetry is a relatively low-threshold method for generating 3D models, both economically and technically. Its principle is first based on the montage of many object photos, which were taken from as different perspectives as possible in close succession. Serially produced image series or, in the special case of historical photo documents, found sources are used, as long as the material situation meets the technical requirements.
Using software, a triangular mesh of the object is calculated by searching for characteristic, corresponding structures from the respective image series and the inherently captured texture is digitally superimposed on it. The result is a three-dimensional representation in which both the plastic impression and the reproduction of the surface are convincing.
