Development of an enhanced video location and tracking system foran XY servo table

摘要

A PC equipped with a monochrome screen capture card and dedicatedcamera, is used to provide position feedback for an automated trackingsystem. It is shown how object location information can be extractedfrom a composite video signal to provide position feedback forclosed-loop control of a 2-DOF servo-driven tracking system.Difficulties encountered are highlighted and conclusions are drawn fromexperimental observations
