Vision Targeting

[Chris Hibner]

There are differences this year that I've noticed:

1) the vision targets are behind the glass in the driver station. If you try to detect them at an angle (like us), the glass kills probably 50% of the light that reflects back to the camera. Bigger angles mean more lost light. Our great camera calibration from our home field was useless at the event. We learned a big lesson there: put some lexan in front of the vision target at home.

2) Delays and flutter in the mechanism that hides the hot-goal indicator result in having to wait a lot longer than we expected to be able to detect which goal is hot. If you're only shooting one ball, it's not a very big deal. If you're trying for multiple balls in hot goals, then this wait becomes significant.
