Basically, you can tell how many targets there is by the number of pixels your camera counts, distance also affects this factor.

True, but distance would affect height and width of the box, whereas I believe two targets only primarily affects the width, so I think you could probably compensate for it fairly effectively with some basic math.

I'm a FIRST relic of sorts, I remember when we used PBASIC and we got CH Flightsticks in the KoP. In my day we didn't have motorized carts, we pushed our robots uphill, both ways! (Houston 2003!)

There's a balance to it all, when the engineers guide the students, and both cooperate to build a robot. There can be no better way then when both sides are in cooperation - the true spirit of FIRST. - Jim McGeehin [more]
