It depends on how much resolution you need. If facial wrinkles and moles are important to capture, then the aardvark is correct; you'll need a pro system at a pro price. But if a general impression of a person's face and body is sufficient, then the consumer-grade scanners will work, and the price is much lower. The Sense scanner, for instance, which lists for $399, does a pretty good job with objects the size of a human. It has some limitations in common with all the other scanners based on the Primesense sensor - it won't work in full sunlight, it's easy to lose tracking, and the resolution is limited to about 1mm granularity, but it captures color as well as form, the software for processing the scans is pretty good, and you can generate printable models with it.
