I don't really know. What I understood, in particular from the Chinese 
example, was that the hardware came 'cheap' as only a perfectly common 
digital camera was needed and no sophisticated laser-controlled stuff. 
And a simple stepladder in addition, to get around the statues. The same 
applied for the students with their drone. Concerning the software, I 
have no idea. The results looked good however, and I doubt that they had 
any particularly high expertise in the matter.
