CHANDLER, J.H. and BUCKLEY, S., 2016. Structure from motion (SFM) photogrammetry vs terrestrial laser scanning. IN: Carpenter, M.B. and Keane, C.M. (eds.) Geoscience Handbook 2016: AGI Data Sheets, 5th ed. Alexandria, VA: American Geosciences Institute, Section 20.1.
Structure from Motion (SfM) has its roots in the well-established spatial measurement method of photogrammetry, but is becoming increasingly recognised as a means to capture dense 3D data to represent real-world objects, both natural and man-
made. This capability has conventionally been the domain of the terrestrial laser scanner (TLS), a mature and easy to understand method used to generate millions of 3D point coordinates in a form known as a “point cloud”. Each technique is described and noted for its strengths and weaknesses.
