Scanning a person in full-size is always a problem because it's living (and moving). Who can stand still for some seconds? That means in any case it's necessary to underpin the person by several supports. These pillars can be removed easily afterwards in DAVID's Shape Fusion.
The scanner could look like this Japanese one:http://www.youtube.com/watch?v=86hN0x9RycM
That means it should consist of three, or better of four single scanners standing around the person. Each scanner has its own video projector and a camera. The 3 or 4 scanner units would be started one after the other to capture the 3D data. Only one DAVID license would be necessary!
But it’s costly, maybe that’s the reason that up to now nobody of the DAVID forum has tried it. So be the first and give it a try.
PS. What people already had done here on the forum are e.g. these scanners:

2. A turn-around scanner:viewtopic.php?p=18622#p18622
