The math used to calcualte range to the target presumes the camera-to-upper-tape distance is bigger than the height of the target. If this is not true, you'll get NaN for the calcualtion of the distance (sqrt of a negative number).
When this happens, we can probably presume whatever we're looking at isn't actually the target we're looking for.
Update the logic in the vision target qualification system to detect this, and override to say there is no target visible when this happens.
