As an undergrad I worked with a professor who was doing precisely that! https://sense-lab.github.io/pubs/pdf/solomon_nature_2006.pdf

I hadn't thought about this in a long time. Looks like her lab is still going strong doing research at the intersection of biology and robotics on whisker-based sensing:

Thin lightweight whiskers are going to be challenging to manage on a propeller-driven vehicle. They'll get blown all over the place. Having them extend out past the propellers will likely get them tangled in the propellers.

A cage around the drone, there are kids toys like this, and also commercial products for inspection. Prevents contact with other objects, contact can be sensed and reacted to. https://www.flyability.com/elios-3

Doesn't protect against everything, like Spanish Moss which dangles from trees, but that is a lot bigger than a long thin wire.

Would help avoid damage with other misrecognized or ignired objects, too.

Sorry, not profitable enough, not a "team player". Please enjoy these weekly 1:1s with your manager and HR.

We experimented with a rig with more cameras on it (four, in a square) but the baseline of the cameras on the drones we were using could be measured in centimeters, so the vertical stereo pairs didn't provide much better results. Further, more cameras means more power, more weight, and much more expensive on-board processing (which also will require more power).

OpenStreetMap supports annotating poles and theirs cables. It's common for power lines (local and long distance). There are also annotations for communication lines (https://wiki.openstreetmap.org/wiki/Tag:communication%3Dline).

There are also public and proprietary "aviation obstacle" databases across the world.

Any one particular cable might not move often, but if a telco owns N bucket trucks it's a safe bet that about N cables move every workday.

Telcos are notoriously secretive about the location of their fiber. They even got most state legislatures to exempt it from state-level FOIA laws.

All cables? Everywhere in the entire country? Accurate to the centimeter level and updated on the hour?

Edit: This was flippant, but the real issues are: any map you get will be incomplete and obsolete almost immediately and cables move and sway in the breeze.

Yes but tradeoffs with delivery speed, and thin wires are still hard to detect with limits on vision processing.
