All it'd take is a simple background subtraction. Take a calibration image with nothing on the field. Then you grab an image during a match, and delete your calibration image from the image you just grabbed. As for velocity, you simply record the position of your object(s) , find the distance it traveled between frames and divide by frame time.

We do a background subtraction for depth tracking with the kinect (and asus xtion) and it works perfectly.

I don't think knowing the velocity (speed and heading) of another robot would be that useful considering most robots can turn on a dime, and some don't even hsbe to turn to go in a different direction. For game pieces it'd be somewhat useful, but I feel that having a camera above your intake would be more beneficial, but that's just me.
