Re: Camera Tracking
Great paper! We did something similar last year where we calculated our starting position based on the perceived size of the circle target and their overall ecentricity. It worked extremely well and was much more reliable than having our drive team dial in our starting position.
While it probably does not matter too much this year, I was curious whether any one knew how the 2" retroflective tape would be applied to the 3" target circles ? A couple camera shots from kickoff suggested that the 2" tape would simply be centered in the circle with rounded (to the circle) tops & bottoms (i.e. the whole circle is not covered). This NI paper showed nice 'round' (red) targets. I've found no formal documentation on this subject and would be curious as to the specific retroreflective configuration. Thanks, John |

Re: Camera Tracking
The construction of the targets wasn't finalized when the paper was written. The circular targets in the paper are slightly smaller and totally covered. Your description matches what I believe the official targets will look like.
A 1x4" strip above and below, and a 2x2.75 strip rounded on top and bottom centered on the circle. Greg McKaskle |
