Long distance multimodal biometric system and method
First Claim
1. A system for multimodal biometric identification, the system comprising:
- a first imaging system that detects one or more subjects in a first field of view, the one or more subjects 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 reflecting from the first biometric characteristic, the first biometric characteristic being positioned in a second field of view which is smaller than the first field of view, and the first image including first data for biometric identification;
a third imaging system that captures a second image of the second biometric characteristic according to second photons reflecting from the second biometric characteristic, the second biometric characteristic being positioned in a third field of view which is smaller than the first and second fields of view, and the second image including second data for biometric identification;
at least one active illumination source that emits the second photons to be reflected from the second biometric characteristic; and
a controller that operates the first imaging system, the second imaging system, the third imaging system, and the at least one illumination source according to programmed instructions, the controller comprising at least one of;
one or more independent sub-controllers and one or more interdependent sub-controllers.

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.

13. A method for multimodal biometric identification, the method comprising the steps of:
-
identifying one or more subjects in a first field of view; selecting a targeted subject from the one or more subjects, the targeted subject having a first biometric characteristic and a second biometric characteristic; aligning a second field of view to the first biometric characteristic, the second field of view being smaller than the first field of view; aligning a third field of view to the second biometric characteristic, the third field of view being smaller than the first field of view and the second field of view; actively illuminating with second photons the second biometric characteristic; capturing a first image of the first biometric characteristic according to first photons, the first image including first data for biometric identification; and capturing a second image of the second biometric characteristic according to the second photons, the second image including second data for biometric identification. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
