I took the model of my upper teeth and used dental floss (irony) to suspend it from a lamp in my apartment. My thought being that with the model suspended in mid air I would be able to take pictures from every angle more easily. Photo of the setup below-
Here is a screen grab from the scan in 123D Catch-
I must say that I was quite disappointed with how this turned out, it basically interpreted the model as a curved plane, when I really wanted to get a scan of the volume of each tooth. Despite this setback I decided to see if I could trouble shoot the problem.
These were my thoughts:
First, I thought that not having the model on a ground plane was making it difficult for the software to find enough points of reference for the depth of the scene. Secondly I had the idea to place small colored markers on each tooth to help the computer have more points to track. I will try and set this up again and see if we can get some better results.
