Abstract:
1. A system for passively and unobtrusively detecting movement of people or objects through a passageway where detection of people or objects moving in a disallowed direction through the passageway is critical and a rapid response to a detected movement necessary comprising: a stereoscopic sensor sensing the person or object as it moves through the passageway in any direction and generating successive individual frames of three-dimensional imagery of the object; a processor integrated with the sensor and processing the individual frames of imagery to distinguish the person or object from other people and objects simultaneously moving through the passageway regardless of the direction of movement of the people and objects; an alarm indicator responsive to an input from the processor if the processor determines a person or object is moving through the passageway in the disallowed direction to promulgate an alarm whereby any people or objects moving in the disallowed direction are passively and unobtrusively detected and their movement reported; and at least one workstation, said workstation including at least one display configured to display a graphical user interface and one or more of said individual frames of imagery generated by said stereoscopic sensor, said alarm indicator being incorporated in said workstation to provide an alarm indication using the display.
