Photogrammetry
The science and technique of obtaining reliable measurements and 3D models from overlapping photographs — the standard method for heritage surface documentation at scale.
Structure from Motion(SfM)
The photogrammetric algorithm that reconstructs 3D geometry from a set of overlapping 2D photographs by tracking common feature points across images.
Ground Control Points(GCPs)
Surveyed reference targets placed in the scene before photogrammetry or drone survey, used to scale and georeference the output to real-world coordinates.
Orthophoto
A geometrically corrected aerial or terrestrial photograph in which scale is uniform throughout, suitable for precise measurement — unlike a perspective photograph.
