AGILE NON-CONTACT BIOMETRIC SENSOR
Exemplary embodiments include an agile non-contact biometric sensor apparatus, having a sensor that monitors a field of view for a user, an imaging system that captures one or more pieces of biometric information from the user, and a pan-tilt device that orients the imaging system to a location of the user in the field of view detected by the sensor.
1 . An agile non-contact biometric sensor apparatus, comprising:
a sensor that monitors a field of view for a user;
an imaging system that captures one or more pieces of biometric information from the user; and
a pan-tilt device that orients the imaging system to a location of the user in the field of view detected by the sensor.
2 . The agile non-contact biometric sensor apparatus of claim 1 , further comprising a processor configured to receive an indication of the location of user in the field of view from the sensor.
3 . The agile non-contact biometric sensor apparatus of claim 3 , wherein the processor is further configured to provide the pan-tilt device with the location of user in the field of view from the sensor.
4 . The agile non-contact biometric sensor apparatus of claim 1 , wherein the imaging system is a contactless fingerprint acquisition device.
5 . The agile non-contact biometric sensor apparatus of claim 2 , wherein the sensor detects a presence of a hand of the user inside the field of view and responsively provides a signal to the processor that indicates a location of the hand in the field of view.
6 . The agile non-contact biometric sensor apparatus of claim 2 , wherein the processor provides the imaging system with the location of the user in the field of view and the imaging system responsively adjusts one or more operation parameters of the imaging system.
7 . The agile non-contact biometric sensor apparatus of claim 6 , wherein the one or more operation parameters of the imaging system comprise an optical zoom, a digital zoom, and a focus.
8 . A method for capturing fingerprint data with an agile non-contact biometric sensor apparatus, comprising:
monitoring a field of view for a hand by a sensor of the agile non-contact biometric sensor apparatus;
based on determining that the hand is present in the field of view:
receiving a location of the hand from the sensor;
pointing an imaging system of the agile non-contact biometric sensor apparatus at the location of the hand; and
capturing fingerprint data from the hand with the imaging system.
9 . The method of claim 8 , further comprising based on determining that the hand is present in the field of view adjusting a focus and zoom of the imaging system based on the location of the hand.
10 . The method of claim 8 , wherein the imaging system is a contactless fingerprint acquisition device.
11 . The method of claim 8 , wherein the imaging system is mounted on a pan-tilt device that controls an orientation of the imaging system.
12 . The method of claim 8 , further comprising comparing the captured fingerprint data with one or more records of a database of known fingerprints.
13 . The method of claim 11 , wherein capturing fingerprint data from the hand with the imaging system comprises taking an image of the hand with a camera of the imaging system and using the pan-tilt device to adjust a position of the camera such that a center of a fingertip of the hand is in the field of view.
14 . The method of claim 8 , wherein capturing fingerprint data from the hand with the imaging system comprises varying a focus of a lens of a camera of the imaging system and acquiring an image at each focus position.
15 . A computer program product having a non-transitory computer readable medium storing instructions for causing a computer to perform a method for capturing fingerprint data with an agile non-contact biometric sensor apparatus, the method comprising:
monitoring a field of view for a hand by a sensor of the agile non-contact biometric sensor apparatus;
based on determining that the hand is present in the field of view:
receiving a location of the hand from the sensor;
pointing an imaging system of the agile non-contact biometric sensor apparatus at the location of the hand; and
capturing fingerprint data from the hand with the imaging system.
16 . The method of claim 15 , further comprising based on determining that the hand is present in the field of view adjusting a focus and zoom of the imaging system based on the location of the hand.
17 . The method of claim 15 , wherein the imaging system is a contactless fingerprint acquisition device.
18 . The method of claim 15 , wherein the imaging system is mounted on a pan-tilt device that controls an orientation of the imaging system.
19 . The method of claim 15 , further comprising comparing the captured fingerprint data with one or more records of a database of known fingerprints.
