You're talking about producing a lot of vision processing code if you're trying to account for the floor as well... just know that the floor isn't the only thing that appears white (people's t-shirts will appear white as well, so how does your camera know where the floor is? a toddler even has difficulty with that)

To the camera (or the robot) it's not so obvious... you might want to rethink your algorithm to account for the fact that perception of height from a single focal point depends on an apparent distance due to size on the image rather than the actual distance or height. (many people seated together with similarly colored t-shirts far away from the camera could look like a target).

I'm guessing that the floor will be out of the field of vision for most people's cameras (especially if you're near the target, looking up), so this is probably not a good choice for a reference.
This thread was intended more as a joke than anything else (I guess also as a warning to teams that may try to track a single color). I can almost guarantee that we'll have some rogue autonomous bots firing into the crowd at least once this competition. (and maybe at the judges, too, depending on what colors they're wearing)
who knows, maybe a camera will even track the screen above the field (which will sometimes display a target pulled behind a robot).
luckily, the point of this year's competition will not be shooting.
