How to track target

how does one go about tracking the circle as the target instead of a colored object?
Would it be better to target the FIRST logo in the middle though? Any input on algorithms used would be helpful. We are [unfortunately] using LabView this year to program

Re: How to track target

The LabVIEW robot project has vision target tracking built in. It already finds the black circle for you.

Re: How to track target

how do we get the camera to turn on the servo's? We keep making basic programs that should turn the servo's but it has just stumped us!:mad: does anyone have any bases that we could awork from and see what we are doing wrong? thanks for any help! we could use any pointers we can get. :)

Re: How to track target

There is an example which updates servos to center a vision target. It is not a black circle, but they are pretty compatible.

Make sure you put a jumper on the +V pins on the PWM you connected the servo to. I made that mistake initially.

Re: How to track target

im on a rookie team, and i have been looking around the robot project, and where is this built in tracking program in the project, i have not seen it looking around.

Re: How to track target

turns out our build team wiring was alittle finicky :) it works now! but thanks for the help we did edit out programming a little.

The Vision Processing vi should be listed in the Project Explorer window, under the Team Code. Robot Main calls it.

Thanks for the answer but i looked in there and i didnt see anything dealing with finding the target. Am I missing something when looking in there? Or did I misunderstand What you said concerning the program finding the target for you?

I think you must have missed the "Find Circular Target" right in the middle of it.
