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.
- posterboy 10y agowith radar and lidar equipped cars, these models will become a commodity quickly
- hengheng 10y agoFixed 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)
- RangerScience 10y agoI know they merge with aerial scans, but I don't know if it's drone-based.
- metalliqaz 10y agoBefore 'drone' became a buzzword, they were just called remote-controlled airplanes.
- khedoros1 10y agoTo 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
- nerfhammer 10y agoHow does the drone know its exact elevation? GPS is only accurate within like 10 meters
- mlla 10y agoOne 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 http://diydrones.com/profiles/blogs/navio-rtk-demonstration
