I'd be curious if anyone has devised a creative method of performing clean grids for photos/video capture? Doesn't really work with laser levels you would find in a hardware store(unless you have dozens of them pre-measured out).
In residential properties I can see this not being much of an issue, but large commercial or industrial could definitely benefit from such an approach. Stick the camera on a RC car or a roomba? heh.. fun. I'm reminded of Photogrammetry methods from the likes of DroneDeploy or Pix4D where you can make pre-programmed routes, but that's using GPS, a feature lacking in the RC/Roomba idea.
