Structure from motion (SfM) is a photogrammetric range imaging technique for estimating three-dimensional structures from two-dimensional image sequences that may be coupled with local motion signals. It is studied in the fields of computer vision and visual perception. In biological vision, SfM refers to the phenomenon by which humans (and other living creatures) can recover 3D structure from the projected 2D (retinal) motion field of a moving object or scene.
Steve Davis provides instruction for constructing 3D models using Agisoft Photoscan, focusing on the use of Structure from Motion to document archaeological excavations and artifacts. Students then will be given instructions for collecting their own photographic data to create a 3D model using either 123D Catch or Photoscan.
