Another approach seems to be using Microsoft Kinect (x-box) or Asus Xtion sensors under Microsoft Windows with the German software Reconstructme, looks impressive. http://reconstructme.net/
Recontructme appears to be free for non commercial use.
The software enables 3d scanning captures in real time, from a face to a car, scanning around an object or room produces a model in scalable 3d metric space. The model is then exportable to common 3d formats such as 3ds, obj or stl. Best regards.
