# Photogrammetry
Photogrammetry is the collection and organization of reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena.
Photogrammetry was first documented by the Prussian architect [Albrecht Meydenbauer](https://opus4.kobv.de/opus4-btu/files/749/db186714.pdf) in 1867. Since then it has been used for everything from simple measurement or color sampling to record complex 3d <a href="https://en.wikipedia.org/wiki/Motion_field">motion fields</a>.
