Abstract
The Distant Human Identification (DHID) system is a master-slave,
real-time surveillance system designed to acquire biometric imagery
of humans at a distance. A stationary wide field of view master camera
is used to monitor an environment at a distance. When the master camera
detects a moving person, a narrow field of view slave camera is
commanded to turn to that direction, acquire the target human, and
track them while recording zoomed-in images. These zoomed-in views provide
meaningful biometric imagery of the distant humans, who are not
recognizable in the master view. Based on the lenses we currently use,
the system can detect and track moving people at distances up to
50 meters, within a 60 degree field of regard.
