Method and apparatus for iris biometric systems for use in an entryway
View Patent ↗A method and apparatus for designing an iris biometrics system that operates in minimally constrained settings. The image acquisition system has fewer constraints on subjects than traditional methods by extending standoff distance and capture volume. The method receives design parameters and provides derived quantities that are useful in designing an image acquisition system having a specific set of performance requirements. Exemplary scenarios of minimally constrained settings are provided, such as a high volume security checkpoint, an office, an aircraft boarding bridge, a wide corridor, and an automobile.
1. A computerized method for designing an iris biometrics system, comprising:
receiving, at a user interface, a plurality of design constraints for a minimally constrained environment related to a doorway;
calculating, by a processor, at least one calculated parameter; and
providing, by the processor, a design for an iris biometrics system that operates within the plurality of design constraints, the design being based on the at least one calculated parameter; and
displaying the design at the user interface;
wherein the iris biometrics system includes a plurality of illuminators, and a plurality of cameras, and the design includes positioning the illuminators and cameras in substantially the same plane.
2. An doorway iris biometric system produced by the method of claim 1 .
3. The method of claim 1 , wherein the illuminators and cameras are positioned in substantially the same plane as the doorway.
4. The method of claim 1 , wherein the illuminators and cameras are positioned over the doorway.
5. The method of claim 1 , wherein the illuminators and cameras are positioned above the doorway in substantially the same plane as the doorway.
6. The method of claim 1 , wherein the at least one calculated parameter comprises a camera standoff distance.
7. The method of claim 1 , wherein the at least one calculated parameter includes a height requirement.
8. A system for designing an iris biometrics system, comprising:
a user interface for receiving a plurality of design constraints for a minimally constrained environment related to a doorway;
a processor for calculating at least one calculated parameter and for providing a design for an iris biometrics system that operates within the plurality of design constraints, the design being based on the at least one calculated parameter; and
wherein the iris biometrics system includes a plurality of illuminators, and a plurality of cameras, and the design includes positioning the illuminators and cameras in substantially the same plane.
9. The system of claim 8 , wherein the illuminators and cameras are positioned in substantially the same plane as the doorway.
10. The system of claim 8 , wherein the illuminators and cameras are positioned over the doorway.
11. The system of claim 8 , wherein the illuminators and cameras are positioned above the doorway in substantially the same plane as the doorway.
12. The system of claim 8 , wherein the at least one calculated parameter comprises a camera standoff distance.
13. The system of claim 8 , wherein the at least one calculated parameter includes a height requirement.
