New Research Video Tutorial on Creating 3D Models from Digital Photos

Master’s student Jon Sanfilippo recently completed a short, informative video on Agisoft technology. Read more about the motivations behind the project below. Click here to watch the video!

In an era of ever evolving technology, we are always looking for new ways to obtain better data for research; Agisoft (http://www.agisoft.ru/products/photoscan) presents a unique opportunity for just that.  The program makes use of digital photographs that can be translated into a 3 dimensional model.  In the study of streams and stream morphology, the current methods used for resolving bed topography and stream bed roughness have included auto levels, total stations, Wolman pebble counts, and potentially green LiDar (very expensive).  Agisoft in the right situation, low turbidity and shallow water, can resolve bed formations, topography, and roughness with a water proof camera, a reasonably priced software package, and for larger areas a glass bottom viewer.
