Scanning human bodies

[pbourke]

I'm well versed in the use of PhotoScan and PhotoScan Pro.
In my current project I will be assembling a 100-150 (exact number still to be determined) camera rig for capturing full body humans. However, we are not interested in texture and the models will be largely unclothed, just underwear or swin gear. In addition some of the models will have blemish free skin and so I'm concerned about the number (or lack of) feature points that may be found.
My question, does anyone have experience or advice in possible ways to painting, taping, or otherwise preparing human skin for photography. We seek the most accurate reconstructed surface meshes ... again, won't be using the texture maps at all so there are no constraints on the surface preparation except that it doesn't perturb the surface, and of course is safe.

Hello pbourke,

For better result it is recommended to apply a non-regular texture pattern. I think that using some kind of washable color spray would be fine. You can even mix a few colors.

Too large or too sparse applied texture elements wouldn't help much.

An example of good texture pattern:

For your information, and perhaps for others, this is what I did.

Worked extremely well. Really high quality models with no editing except closing the bottoms of the feet.
