Video tracking

[Marco Trapanese]

Hello,

I know there are web cams that may track my face on its own movements. I
also know there are software to guide the telescope using a star as
reference point.

What I'd like to know is if there is a software that tracks an image
from a web cam and outputs its movements in order to control motors and
recenter the image.

Thanks

Yes, of course. You can write your own if you like.
We setup an motorized X-Y gantry for a webcam and
wrote software to track worms, well maggots, actually.
We illuminated them with a ring of LEDs attached to
the camera, and in early tests used red LEDs. This
didn't work because the worm would always turn away
from the light, and the camera/light would follow,
so he/she/it? ended up going around in a continuous
circle. Changing to 850nm IR LEDs fixed that problem.

Well, please may you provide some useful links about this concept? Or
better, what should I search for? I'm not sure about the right keywords
to use.
