Its just texture mapped laser scanning but they must be scanning from multiple directions and using some point cloud re-meshing to get the model back from it. Its all not that new but its very nicely done. Cambridge uni does a lot of this sort of stuff.

Now if you had this model as a starting point then that thing that Waldronate mentioned with the 3D twin digi camera thing would come into its own. You could upres the model significantly with that.

You will be seeing little sesna type planes with google written on the side soon...
