Hey! Welcome to the forums! I just became a new user a few minutes ago myself! and i'm starting to research up on 3D scanners as well as 3D printers. I've learned in a book called Meet the Kinect by Sean Kean, Jonathan Hall, and Phoenix Perry, they talked on some stuff regarding how the kinect works, setting it up to your laptop, etc.
so you can use the kinect as a scanning tool. I've tried it a little myself to scan my whole family room, although it didn't come out the best I wanted it. scanning individual items instead of a room might yield better results though.
If you google skanect by Manctl, that program should still be free to use to be able to scan objects using the kinect (and it might get upgraded and a better version for a fee), although you'll have to download and install the drivers for the kinect first (in a certain order no less), and you will need a USB AC Power Adapter Supply Cable for the kinect, so that you can plug it into your PC, since the kinect will need to draw power from a source. it costs around $4-6 on amazon. although I have to say, the kinect is much more capable than just being a 3D scanner.
artec3d also looks good for a kinect scanner software
googling the top ten best kinect hacks, #2 and 3 talks about other scanner software, especially #2, which talks about scanning people and objects.
also, search for NextEngine 3D Scanner, I just did some research on that and it looks like something definitely worth looking into, but it will set you back $3000, but the way that you're wishing to scan a person, this scanner seems to be following a pretty similiar pattern.
I'm just an eager guy trying to learn the ways of the 3D printer/scanner world, and i'll share whatever I can! I hope this helps! let me know how the progress works for you! i'd love to hear it!

sorry I couldn't help on the ps3 move! I don't have a ps3 yet lol, so I don't know much about it.
