Another one from the "How-good-is-my-new-phone-for-photogrammetry?" testing series:
Cast of the early medieval tombstone from Niederdollendorf, Germany, shot in June 2019 in the special exhibition in the LVR-LandesMuseum Bonn with a RugGear RG850 smartphone. Guerilla scanning style - 63 pictures in less than 7 minutes under ambient lighting. The base of the tombstone was mounted in a pedestal and was therefore not accessible.
For more information on the tombstone itself see https://de.wikipedia.org/wiki/Grabstele_von_Niederdollendorf#/ or http://www.suehnekreuz.de/nrw/niederdollendorf.htm (in German).
Modeling was not without problems - the dimensions of the limestone block might be a bit distorted. Feel free to compare the results with the two other Niederdollendorf tombstone models on Sketchfab: https://skfb.ly/6KGS6 (incomplete model of a cast, base is missing) and https://skfb.ly/6LDzt (complete tombstone including the base).
