Vision Targeting for Aerial Assist 2014
Alright what are some ideas for vision targeting this year for the 2014 game? My ideas were to for autonomous use the hot zones to target.
Any ideas what are your ideas. I'm currently looking at the game/arena setup PDF. |

It seemed pretty clear that that was the intention of the hot zone from the very beginning.

Track the hot zone, the balls (calculate its speed and go to where it will be autonomously), track other robot and pass the ball so it will meet them in their path. Track opposing robot so you can autonomous move around them. Track the vision tape on the wall and index from that.
Not going to lie, this this very elementary stuff. |

But I don't see how you can possibly argue that tracking other robots and/or flying ball(s) is elementary. That betrays either a misunderstanding of how difficult it really is, or such a deep mastery of computer vision that you've forgotten how difficult it is to the inexperienced. I'll assume the latter. |

The ball is a fairly easy. You already know how big the ball is (therefore its diameter). You could simply use the area of the ball to calculate how far away it is. It would take some testing, but it is very doable. Then the same math applies to the previous example. |

Take a look at 341's vision paper. It's well written and has what you need to learn! While the programming isn't necessarily the easiest part of vision, the algorithm still seems quite simple to work with!

This is simpler than what it seems. Have you gotten pence installed with python bindings or Windows c++? Read 341's vision whitepaper!!! |

I doubt there will be much practical use in tracking anything but the hot zone. Anything else and you're adding unreliable gimmicks to your code. Letting the drivers practice for a few extra days at picking up and shooting is most likely much more beneficial than a ball tracking algorithm.
What I'm worried about is the brightness of the led strips around the hot zone. It seems like they will be a bit dim to track. If anyone has seen stills of teams using the reflective tape, you will see that the leds have to be blindingly bright for them to be as easy to destinguish. |
