How to perform better facial 3d scan

[Naderfagundes]

Hello my friends, I'm doing 3d facial scans from iphone's videos ( see example: https://youtu.be/TwmFIiI679k) . I can't get good scans of the teeth. I know that its because tooth are shinny. How can I surpass this problem?

Hi Naderfagundes,

There isn't much you can do with teeth and photogrammetry unless you coat them in something to reduce/eliminate the shine (Not ideal, I'd imagine!) Alternatively you could look into cross polarization, but it's going to be a struggle, especially using an iPhone and not a proper multi-camera DLSR studio setup.

Thank you Cam3d. We have a powder that was used with an old intraoral scanner. I'll try it.
