That'll set up the pi and a table specifically for vision. If you launch OutlineViewer from Eclipse (WPILib > Launch OutlineViewer), you'll be able to see the values update in realtime.

Then to publish the results from the vision processing

visionTable.putBoolean("Have target", haveTarget);
visionTable.putNumber("Angle to target", angleToTarget);
...

In your robot program, you'd also declare a table for vision just like we did on the pi. To read the values the pi is publishing, use the corresponding 'get' methods

haveTarget = visionTable.getBoolean("Have target", false); // default to false
targetAngle = visionTable.getNumber("Angle to target", 0); // default to 0
...

Does anyone know of a vision processing tutorial?
