Photogrammetry is a very fascinating subject that leverages an key subfield of computer vision related to structure-from-motion (SFM) and photo reconstruction. Long story short, using the principles of multi-view geometry, one can derive a 3D model of the scene with just a series of static images.

To produce these reconstructions I use the excellent COLMAP toolkit that provides an automatic pipeline for converting a group of images into 3D models. Checkout their documentation for details on how SFM works.
