A system and method for assuring a high resolution image of an object,
such as the face of a person, passing through a targeted space are
provided. Both stationary and active or pan-tilt-zoom cameras are
utilized. The at least one stationary camera acts as a trigger point such
that when a person passes through a predefined targeted area of the at
least one stationary camera, the system is triggered for object imaging
and tracking. Upon the occurrence of a triggering event in the system,
the system predicts the motion and position of the person. Based on this
predicted position of the person, an active camera that is capable of
obtaining an image of the predicted position is selected and may be
controlled to focus its image capture area on the predicted position of
the person. After the active camera control and image capture processes,
the system evaluates the quality of the captured face images and reports
the result to the security agents and interacts with the user.
