In-depth tech details about the 3d scanned Nefertiti

[obelix]

Hello,

after reading several blog and tech articles about the 3d scanned Nefertiti (here and here) i decided to test it myself. I printed out a 1:1 replica of the bust (50cm, 70h, 3kg PLA, 0,2mm Layer height, 2 pieces in total) and scan it with the Kinect, as described in the articles.

Don’t forget that the main purpose of the action is not to show that you’re able to perform such scans undercover but raise awareness about the political problem with stolen art and art in the public domain.

I wrote everything down and you can take a look at it on my blog here: https://www.db4cl.com/3d-scanner/technical-analysis-3d-scanned-nefertiti/

As soon as they said they used a kinect I knew it was fake, a kinect is the worse kind of 3D scanner it can only do rough blobs.

and photogrammetry can never do surface detail if the object is painted.

But i think with photogrammetry and heavy post processing you could get there in some way. I think some of the details could be added by hand. Just with the small resolution pictures from Trigonart or looking at it from 1-2m distance (in the museum) you can’t verify the accuracy of the detail itself.

“Who cares how they got the data or how they scanned it in the museum, it’s where it should be: in the public domain.” Fantastic
