I don't necessarily agree with number 3. They should simply feed the image to the driver station and let them do the heavy lifting of finding the position of the robots. I know the arguments against this ("teams wouldn't have data to play around with before competition"), but all you'd need is an image from all 4 of those cameras with no robots or game pieces in it, then implement a transformation on the image like Yash mentioned to change the perspective. You could even do sterio vision (with homograph (yash)), to calculate distance and use simple trig to calculate distance.

As for number 4, if the fms did number 3, and it sometimes didn't work, it should be counted as a field fault, not an "oh well" situation.
