Creating 3D Models of Artifacts and Features using Photogrammetry

Summary

During the 2015 and 2016 University of Texas at San Antonio Field Schools we made use of new low-cost photogrammetry techniques to document metates and rock ring features at Early Agricultural period sites along the Upper Gila River in southeastern Arizona. We systematically photographed a number of ground stone tools and rock ring features using point-and-shoot cameras. These photos were then processed using Agisoft’s Photoscan software to produce colored 3D computer renders of the artifacts and features. We were able to demonstrate that our method produces models that are accurate to the shape and scale of the physical items. This method also allowed us to document them with minimal impact to the features and without collecting the artifacts. While still in the early stages of development, this approach may have long-term potential to enhance archaeological documentation and collaboration.
