Compact biometric acquisition system and method

摘要

A method of determining the identity of a subject while the subject is walking or being transported in an essentially straight direction is disclosed, the two dimensional profile of the subject walking or being transported along forming a three dimensional swept volume, without requiring the subject to change direction to avoid any part of the system, comprising acquiring data related to one or more biometrics of the subject with the camera(s), processing the acquired biometrics data, and determining if the acquired biometric data match corresponding biometric data stored in the system, positioning camera(s) and strobed or scanned infrared illuminator(s) above, next to, or below the swept volume. A system for carrying out the method is also disclosed.

主权项

1. A system for acquiring one or more biometrics of a subject, the system comprising:
a sensor to detect a biometric feature of the subject and to acquire two or more images of a corresponding iris of the subject, and one or more infrared illuminators to provide:
infrared radiation at a first infrared radiation level sufficient for the sensor to detect a biometric feature of the subject, andresponsive to detection of the biometric feature by the sensor, a predetermined sequence of pulses of infrared radiation at a second infrared radiation level greater than the first infrared radiation level, the second infrared radiation level being sufficient for the sensor to acquire the two or more images of the corresponding iris of the subject for biometric matching.
