New Article – Using Photogrammetry to Document, Analyze and Reverse-Engineer Grave Markers

This article discusses how to create (using free software) 3D models of historic grave markers, which can be used to explore the effects of various preservation treatments, tracking slope in markers that may soon become unstable, and reverse-engineering elements that may have been lost or damaged. This is the first in a series of articles that will focus on grave markers from the Oak Grove Cemetery in Nacogdoches, Texas. Many thanks to those that offered comments on this manuscript while in prep. Additionally, I would like to thank Ben Ford and the folks at the Society for Historical Archaeology’s Technical Briefs in Historical Archaeology for their willingness to push the boundaries of traditional publication by including 3D figures.

To download the article, simply click on the image of the first page below. To activate the 3D content, you will need to save it to your computer, then open it in Adobe Acrobat or Adobe Reader.

There are a variety of how-to videos distributed by Autodesk that highlight how to make your own 3D models (see below). I encourage you to get out and give it a try!
