re-assembling fragments

Recommended Posts

In talking to some museum conservators, the notion of using 3D software to “put back together" broken ceramic or other artifacts has come up several times. Using the regular 3D programs for this can be very tedious. I was wondering whether there was any software that specifically addressed taking a bunch of models of fragments and efficiently finding how they might fit together.

P Fried,

I don't know how well it would translate to such a context, but there has been work in the computer vision field trying, and succeeding, in solving jigsaws, so there might be something there. Suspect they're geared around 2D, but might be possible to use them to produced an 'unwrapped' solution?

Hi P fried,

I don't know if there is anything off-the-shelf yet, but a couple of articles on computer-vision jigsaw solving: 

https://www.i-programmer.info/news/181-algorithms/4380-faster-jigsaw-solving.html

https://www.researchgate.net/publication/220843444_An_Innovative_Algorithm_for_Solving_Jigsaw_Puzzles_Using_Geometrical_and_Color_Features

 

Another related area which is receiving attention is the DARPA Shredder Challenge - reconstructing documents from images of shredded strips or fragments.
 

Let us know how you get on!

cheers/Dave
