ABSTRACT
There is an increasing need of easy and affordable technologies
to automatically generate virtual 3D models from their real counterparts.
In particular, 3D human reconstruction has driven the
creation of many clever techniques, most of them based on the
visual hull (VH) concept. Such techniques do not require expensive
hardware; however, they tend to yield 3D humanoids with
realistic bodies but mediocre faces, since VH cannot handle concavities.
On the other hand, structured light projectors allow to
capture very accurate depth data, and thus to reconstruct realistic
faces, but they are too expensive to use several of them. We have
developed a technique to merge a VH-based 3D mesh of a reconstructed
humanoid and the depth data of its face, captured by a
single structured light projector. By combining the advantages of
both systems in a simple setting, we are able to reconstruct realistic
3D human models with believable faces
