LONG DISTANCE MULTIMODAL BIOMETRIC SYSTEM AND METHOD
First Claim
1. A system for capturing biometric data from a subject, comprising:
- a first imaging system having a first field of view and capturing at least one first image in which a subject is detected;
a second imaging system having a second field of view;
a third imaging system having a third field of view; and
an adjustment system coupled to the second imaging system and the third imaging system, the adjustment system being movable according to a position of the subject detected in the first field of view, movement of the adjustment system causing the subject to be positioned in at least one of the second field of view and the third field of view, the second imaging system capturing at least one second image from the subject when the subject is positioned in the second field of view, and the third imaging system capturing at least one third image from the subject when the subject is positioned in the third field of view, the at least one third image being determined from the at least one second image and providing biometric data for the subject.

Abstract
A system for multimodal biometric identification has a first imaging system that detects one or more subjects in a first field of view, including a targeted subject having a first biometric characteristic and a second biometric characteristic; a second imaging system that captures a first image of the first biometric characteristic according to first photons, where the first biometric characteristic is positioned in a second field of view smaller than the first field of view, and the first image includes first data for biometric identification; a third imaging system that captures a second image of the second biometric characteristic according to second photons, where the second biometric characteristic is positioned in a third field of view which is smaller than the first and second fields of view, and the second image includes second data for biometric identification. At least one active illumination source emits the second photons.

34. A system for capturing biometric data a subject, comprising:
-
a first imaging system capturing at least one first image and detecting a subject; a second imaging system being movable to track the subject and capturing at least one facial image from the subject; a third imaging system including dual sensors, the third imaging system determining a position of the subject'"'"'s eyes in the at least one facial image and the dual sensors capturing eye images from the subject, the eye images containing biometric data. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A product comprising a machine-readable medium containing instructions for determining biometric data from one or more subjects, the instructions comprising the acts of:
-
receiving a plurality of scene images from a first field of view, each scene image including a background image and a foreground image, the foreground image containing one or more subject images, the one or more subject images including eye images having biometric data corresponding to one or more subjects; detecting, in each scene image, the foreground image relative to the background image; detecting, in each scene image, the one or more subject images in the foreground image; detecting facial images corresponding to the one or more subject images; tracking, in the plurality of scene images, the detected facial images corresponding to the one or more subject images; scheduling the tracked facial images for acquisition of the biometric data; directing a second field of view to the tracked facial images according to the act of scheduling; receiving the tracked facial images from the second field of view; locating the eye images in the tracked facial images from the second field of view; receiving the located eye images from a third field of view; and detecting the biometric data in the detected eye images from the third field of view. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81)
