Take a look at this video:
It is for an app called DroneDeploy.
Has anyone used anything like this for site surveys?
Someone asked about using it with the IPVM calculator. I think it is an interesting idea.
More broadly, 3D mapping for large scale video surveillance systems has been promoted by a handful of big companies but at a huge cost. Doing it with a drone would likely reduce the cost dramatically and it make it much more practical.
What do you think? Interesting? Applicable? Not interesting / not applicable?
