Abstract :
A PC equipped with a monochrome screen capture card and dedicated camera, is used to provide position feedback for an automated tracking system. It is shown how object location information can be extracted from a composite video signal to provide position feedback for closed-loop control of a 2-DOF servo-driven tracking system. Difficulties encountered are highlighted and conclusions are drawn from experimental observations
