I did something similar, but much less complex, for detecting a balloon
and directing the aircraft onto it.  

Todd's stuff looks a lot more complex (and cooler!).

My detection routine ran in realtime quite happily on a battered old
Pentium 3 laptop, and I wrote them in Python opencv (with the help of
pyscho and the IPL module).  I never got to use it in anger because of
the uplink lag.  I'm currently working on stereo imaging using a
beagleboard (slightly more powerful version of a gumstix).
Unfortunately, OpenCV is highly optimised for x86 instruction set
machines, so I'm not sure how badly performance will suffer yet
(currently fighting V4L as we speak).  However, simple object detection
should run ok - after all, it only has to do 1-5 frames a second.
I think I've still got the code kicking around if you want it.
