Re: vision system accuracy

We use LabVIEW and the MS camera. At first it was off but after tuning it has been 100% no fail. At the first district event it would not work correctly for 90 of the event. Toward the end after refinement it started to work and at the second district event it didn't miss.

We use it for all shooting. Its does Auto high goal 100%. It missed one because the ball bounced out of the bot crossing over but its was not the shooter obviously.

Ours is reflective targeting with cross hairs. In Auto it looks for a match threshold and then shoots. In tele, its puts a box up and the drive team aligns the cross hairs and shoots.

To make the adjustments the shooter is on a turret that does azimuth and elevation. The software makes the turret adjust to the target so the bot does not have to move. We just need to be in a general area maybe +- 3-4 feet. Of course the margin can be bigger than that but to be most accurate we keep it in that range.
