I found a damaged and illegible headstone today and wanted to recover the engraving but did not want to disturb it to try for an etching. Instead I attempted to use photogrammetric techniques to 3D model the tombstone and do a “digital etching” by coloring the model by depth. I used my camera phone and AgiSoft PhotoScan and the results were very successful.
