why don't you go work with the vision system some before you go needlessly arguing over green robots, green shirts, and other distractions. IF in the process of trying to make it work you find that it is easily thrown off, then come here to ask questions about how to correct this problem in detection.

Its something any of us interested in vision will half to test, but just ranting back and fourth about all the possibilities of false detection without ever trying the system is a huge waste of time.

Personally, my guess is the focal range of the camera won't be entirely too large, probably green robots on the other side of the field won't be a problem, and defenitely a crowd in the background won't matter, but i'm anxious to work with the vision system before i commit to saying this is the case.

But i urge you - go try something with it before you sit here on chiefdelphi and needlessly banter back and fourth over it, without experience with the device you have no way of knowing, but by working with it some you can learn an awful lot.
