Look at sample program f33-camera.bas: it already prints white text on top of a picture taken by camera, you can replace white text by what you want (red target, buttons etc.)

We worked really hard to do computer graphics over live video back in the mid 80s.
System was used to range and aim a Hughes 20 MM gun.

We did range by horizontal line cursors capturing a tank top and bottom (known height).
But had to characterize the zoom on each camera lens too. They had different response
curves zooming in vs out.

How cool it would be if we could do that kind of thing in BASIC! on live video...
