I am an engineer from Tennessee. I am very new to multirotors.
I am investigating the potential usefulness of UAVs for bridge inspections in hard to reach areas.
There is very little video on the web that show how they may be used for this purpose. A few large companies of very expensive RTF drones mention the use for bridge inspections but none have adequate video or photos proving the ability to do inspections. Aibotix is the only one that comes close to video examples and they are not proof of possible replacement/supplement to traditional bridge inspection.
Does anyone know of a company or videos doing a good job of showing the worth of multirotors for this application?
Also, I am considering building a quadcopter to experiment with the possibility of using them for bridge inspections. (may need to start a thread for this)
Steady hovers close to bridge components (beams, piers, truss members), GPS does not work well under bridges, so sonar,barometer, etc required
Live viewing (FPV system)
Photos (very clear)
Video (HD with possible sound recording from operator, as to narrate the part of bridge being viewed)
Propeller protection (do to proximity of objects and public)
Camera tilt for up/forward/down viewing
Lights for darkened areas (or camera with flash)
