Controlling motors using vision processing help

[Wendy Holladay]

i think i found the +-1. is it in computer distance.vi

target center (-1 to 1) gives an x and y?

[Alan Anderson]

The rectangular target processing produces a Target info array. Each element of that array is a bundle containing X,Y coordinates and computed distance of each recognized rectangle.

[Wendy Holladay]

got it, we have been using the distance, but not the x, y coordinates,

thank u

There is a camera servo example that does a search pattern, moves the camera to point at a colored object, and has a small state machine for overshoot and other situations. You may be able to adapt it or to get the general idea from it.

Can you tell us where this example is?

Thanks!

It's with all the other LabVIEW examples on your programming computer.

When you launch LabVIEW, the "Getting Started" window appears. It has a number of tabs down the left side. One of those tabs is "Support", and it leads to a set of links including "Find FRC Examples..."

I think the specific example Greg is talking about is named "Servo Camera Example.lvproj". It resides in the FRC Robotics > Vision folder.
