You can easily and cheaply scan 3d objects or a person.
They are 2 main ways :
- on a photo base
- with a scanner
In any case, don't expect too much. You'll need to fix and work on the resulted model.
A software reconstructs the 3d geometry by using a bundle of raw photography. The software tries to find the similitude between the picture. So each picture needs to have a kind of common feature ( for example 60% of recovery).
The best method to take the pictures is to use a reflex with a 50mm fixed lens. You need to have many photos. Try to avoid mirrors, glass and reflections. If you scan an object try to have a big contrast with the background.

If they are some glitches, you can manually readjust the pictures.
For many 3d scanner, the scanner emits a signal ( an infrared grid) and measure the reception of that signal ( a camera film the deformation of that infrared grid). Based on the deformation, the software recreate a 3d object.
A cheap 3d scanner is the Kinect, you can find them for about 30€ in a second-hand store (like CashConverter).
The rest of this article focus on the Kinect method
You need to install the driver for Kinect.
