Photogrammetry

Definition

Photogrammetry is a technique that uses photography to measure and map physical objects and environments. This method allows for the accurate capture of three-dimensional data from two-dimensional images, making it invaluable in fields like archaeology and architecture, especially in documenting and analyzing ancient sites and artifacts without disturbing them.
