A multisensor surveillance system for Automated Border Control (eGate)

This paper presents
¹
a multisensor surveillance system used inside an Automated Border Control (ABC) system (more specifically, an eGate). The system consists of two parts: counting the number of persons inside the eGate (person separation), ensuring that no more than one passenger is present; left luggage detection, ensuring that the passenger did not leave any item inside the eGate. These tasks are performed using a top-view mounted sensor inside the eGate, consisting of a trinocular camera configuration comprised of a monochrome stereo setup which delivers depth information, and a color camera mounted in-between, capturing color information. In contrast to already existing ABC solutions, which mostly use electronic sensors, e.g. simple beam technology, for person separation and left item detection, we introduce vision based technologies to elevate the security of such systems to a higher level, also increasing the usability for the border guard. The system achieves real time and had been demonstrated and evaluated at the Vienna International Airport.
