Long distance multimodal biometric system and method
First Claim
1. A system for capturing biometric data from one or more subjects, comprising:
- a first imaging system having a first field of view and capturing a plurality of scene images from the first field of view, each scene image including a background image and a foreground image, the foreground image containing one or more subject images of the one or more subjects;
a second imaging system having a second field of view;
a third imaging system having a third field of view;
at least one programmable device that detects, in each scene image, the foreground image relative to the background image to detect the one or more subject images; 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 a selected one of the one or more subjects detected in the first field of view, movement of the adjustment system causing at least one of a face of the selected subject to be positioned in the second field of view and eyes of the selected subject to be positioned in the third field of view, the second imaging system capturing at least one facial image corresponding to the face of the selected subject when the face of the selected subject is positioned in the second field of view, and the third imaging system capturing at least one eye images corresponding to the eyes of the selected subject when the eyes of the selected subject are positioned in the third field of view, the at least one eye images being determined from the at least one facial 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.
