FACIAL RECOGNITION METHOD AND APPARATUS

摘要

An active-imaging system useful for biometric facial recognition has an optical head with a short-wave infrared (SWIR) imager, an illuminator, and a processor. The imager and illuminator are aligned and mounted on a single pan-tilt stage. The illuminator produces a wavelength of light greater than 1400 nm and less than 1700 nm, which is centered on the imager field of view. An electronics box having power supplies, communications electronics, and a light source for the illuminator can be included. The electronics box is connected to the optical head by an umbilical having cables to deliver light and power to support data communication to and from the optical head. The processor is connected to the electronics box for comparing SWIR-illuminated facial images captured by the imager to a database of visible-spectrum face images.

主权项

1. An active-imaging system, comprising:
an optical head comprising (i) a short-wave infrared (SWIR) imager having a field of view and (ii) an illuminator, wherein the imager and illuminator are aligned and mounted on a single pan-tilt stage such that the illuminator produces a beam of light always centered on the imager field of view, and further wherein the illuminator uses a wavelength of light greater than 1400 nm and less than 1700 nm; an electronics box comprising power supplies, communications electronics, and a light source for the illuminator, wherein the electronics box is connected to the optical head by an umbilical comprising cables to deliver light and power to support data communication to and from the optical head; and a processor connected to the electronics box for comparing facial images captured by the imager to a database of visible-spectrum face images.
