The good people of /r/frc pointed out rule R73.
"R73
Any decorations that involve broadcasting a signal to/from the ROBOT, such as remote cameras, must be approved by FIRST (via e-mail to
frcparts@usfirst.org) prior to the event and tested for communications interference at the venue. Such devices, if reviewed and approved, are excluded from R61."
So I'm going to email them and ask if this idea would be ok (simply somehow getting a camera pointed at the field from a very high vantage point).
Update: I got a reply (I know, so fast?): "Thanks for your note. I’ve forwarded to the rest of the team and this will be considered when the rules are drafted, however and of course, I can’t promise anything."
My request was to allow us to send a message to our driver station wirelessly about where everything is on the field. A team could literally do all of the image processing before sending it and only send motor values to go to the designated point on the field instead of sending a stream of an entire image.
