Yes, that would be the basic idea. I used a hal module to do homing directly, so I didn't actually have to have any G-code callable code. In your case, though, I think you need a combination of initiating the measurement from G-code and then writing the measured values into parameters from a hal module.

Ah, right, I think I remember that I once read about his possibility, but never looked up any details at that time, so I forgot about it again. > I think that was the approach I took.

So I could write my python program (using opencv), call it from the g-code program, pass a few parameters (ca. positions of the tracking marks) and get back some parameters (x/y-offset and angel) and than call G10L2 using these. Right? Sounds easy....
