Tracking pin hole image using a vision chp at the bottom of a black box

[victor joseph]

Track, store & drive two motors in x & y plane untill the real time image on vision chip is tightly aligned with preset neutrl position. Can anyone help me build this unit?

Do you mean that you'd store a reference image that would indicate a "neutral" position and you would drive the two motors (x and y) until there is an alignment? How big would the image be with respect to the motors motion e.g. will you use a bright spot that is always within the field of view, and just move the motors until the spot is centered, or would there be substantially more motion that might require some sort of visual odometry?
