Imagine if police could stand back from a raucous crowd and scan the pack for criminals, without ever having to question a suspect or put their troops in harm's way.
That's exactly what Brazilian police are hoping to do with new eyeglasses equipped with stealthy crime-fighting properties. Dubbed RoboCop glasses after the 1987 action film, the glasses are fitted with a tiny camera that scans up to 400 faces per second. It cross-checks those images against a database of criminals and terrorists, and flashes a small red light inside the glasses if a match comes up. Then the officer knows whom to home in on and whom to leave alone.
Brazilian troops battle drug gangs in Rio de Janeiro last November. Brazilian security forces are testing new RoboCop glasses to scan crowds for known criminals.It's something discreet because you do not question the person or ask for documents. The computer does it, Maj. Leandro Pavani Agostini, chief of military police in the Brazilian city of Sao Paolo, told reporters Monday.
On its optimal settings, the camera can scan 400 faces a second at a distance of up to 50 yards away. But the settings can be changed to recognize faces at a slower pace, at up to 12 miles away.
Agostini said the camera and database compare 46,000 biometric points on a person's face, so the chances of mistaken identity are slim.
