LONDON The Police Information Technology Organisation (PITO) has awarded a contract to Premier Electronics, in alliance with A4 Vision and Global Securities, to install a real time 3D facial recognition technology.
PITO, which provides information technology and communications systems and services to the police and other criminal justice organisations in the U.K., has selected the system to control access to its Biometrics Demonstration Laboratory at its headquarters. In addition to providing access control, it will be used for demonstrations to staff and stakeholders from across the police service and wider government, as well as for evaluation purposes.
The A4 Vision Access 3D face reader system combines standard digital photography with real time 3D facial recognition, providing a very powerful recognition and identification system with the ability to also produce a standard digital photograph.
Geoff Whitaker, Head of Biometrics at PITO, said, “3D face recognition systems have the potential to provide a very effective means of controlling access as well as identifying suspects, and the installation of this state of the art technology at PITO's offices will offer us the opportunity to demonstrate its possible operational benefits to the police service.”
There are two parts to the A4 Vision Access 3D face reader, an enrolment station and an identification/verification unit. The enrolment unit provides both a colour digital picture of the subject and a 3D facial template; it is possible to combine these two formats to provide a 3D-face mask. The digital picture can also be used to generate identity cards and with a special printer holographic prints. The 3D template is taken in real time and requires only a few seconds to be registered; personal details of the subject can then be added to the template as required.
The unit works in the near infrared so controlled lighting conditions are not required for the 3D template; up to 10,000 facial templates can be stored in this unit. The unit also supplies a 100Mb-ethernet connection to allow interfacing with remote identification/verification units and VA server.
The other unit just acts as an identification/verification unit and is connected to the enrolment station via ethernet. Subjects walk up to the unit and either present a card and look into the LCD if working in the verification mode or just look into the LCD if in the identification mode. Pictures are captured between 20 and 60 frames per second giving identification and verification times at under one second.
