A friend of mine works for a company doing something like this with vehicle-mounted scanners. It's like street view on crack - I want to say something like centimeter precision on the measurements, and then they skin it with the photos? It's pretty impressive.

This is also impressive, but for other reasons.



Fixed wing drones can do the same, but it's hard to get the necessary permits. (In fact the data could even be merged with truck mounted lidar)


I know they merge with aerial scans, but I don't know if it's drone-based.


Before 'drone' became a buzzword, they were just called remote-controlled airplanes.


To me, "drone" has some different connotations. It usually seems to mean either:

- Ability to operate out of the pilot's line of sight (through streamed cockpit video or autonomous operation)

- A lazy term for a multi-rotor (3 or more) aircraft


How does the drone know its exact elevation? GPS is only accurate within like 10 meters


One option is to use Real Time Kinematics (RTK) GPS, which can provide accuracy close to few centimetres, see e.g. http://diydrones.com/profiles/blogs/navio-rtk-demonstration


Coool! Thanks.


with radar and lidar equipped cars, these models will become a commodity quickly
