Researchers Jian Xu and Hua Dai have developed a new path planning model for unmanned aerial vehicles (UAVs) that takes wind conditions into account, po...
“Its also stability/focus and speed”
“Drones have a ton of vibrations.”
I think you’re conflating ‘drone’ with a $1000 consumer grade DJI. You can put whatever light, sensor or camera you want any one of a dozen stabilized platforms that are good up to 50 lbs. They’re still not any harder to fly, it’s still a one person job, you could make it two people and have the second person aiming and shooting you can do the work twice as fast.
“highest zoom you can” I didn’t say that, because it would be an intensely stupid statement to make.
If you want sub millimeter resolution of the entire structure, that’s doable. You want infrared? FLIR? all doable.
If you used a stabilized 50MP mirrorless with a fixed lens to take pictures from 10ft away, you could get 2.62 pixels per mm. If you reeled that in to 5ft at a time, you’d get 5.25 pixels per mm.
On a gimbal, with a stabilized lens, vibration would be a non issue. But if you want to beat that horse, you have 6 blades at 10krpm. The maximum frequency of the vibrations would be around 1000hz. (6*10000rpm/60) which means if you’re shooting faster than 1/1000 there’s no time for vibration even if it was completely un-stabilized. That’s easily doable with a light source. That said shooting at 800 would be more than adequate.
And there are cameras with higher resolution and faster sensors available. I’m just taking an upper end off the shelf Nikon at the moment to make the point.
5.25 pixels per millimeter does not sound like very good resolution, especially for close inspection… Did you leave out a modifier or am I misreading something here?

Nah I’m kind of tired of chasing these goal posts here. Go find somebody else to argue with.
