Face collation apparatus and biometrics data collation apparatus
The invention provides a highly-reliable face collation apparatus and biometrics data collation apparatus in both of which when a person is to be identified, even at the time of a collation in which characteristic data on the person approximates to characteristic data on one of the other persons, the characteristic data are comprehensively collated by combination, whereby the person and the other person can be clearly discriminated from each other to reduce collation errors. The face collation apparatus includes a face image acquiring unit for acquiring face images, a storage unit in which a plurality of different face images on each of persons who are collation targets are stored in advance in such a manner as to be associated with each of the persons, a calculating unit for calculating collation degree data obtained by comparing the acquired face images with the stored face images, an extracting unit for extracting face images of high collation degrees by a predetermined number from among the calculated collation degree data, and an identifying unit for identifying a person when all face images of the person are contained in results extracted by the extracting unit.
1. A biometrics data collation apparatus comprising:
a biometrics data acquiring unit for acquiring biometrics data of a person to be identified;
a storage unit in which a plurality of biometrics data for each person of a plurality of persons who are collation targets are stored in advance in such a manner as to be associated with an identity of each person of said plurality of persons;
a calculating unit for calculating collation degree data obtained by comparing the acquired biometrics data of said person to be identified with the stored biometrics data;
an extracting unit for extracting a predetermined number of the highest collation degree data from the stored calculated collation degree data; and
an identifying unit responsive to said extracting unit for matching the acquired biometrics data of said person to be identified with an identity based on a predetermined condition relating to the quantity of biometric data of the person to be identified which are contained in results extracted by the extracting unit.
2. The biometrics data collection apparatus according to claim 1 , wherein the biometrics data acquired is data characterizing a face.
3. The biometrics data collection apparatus according to claim 2 , wherein the biometrics data acquiring unit comprises a camera.
4. The biometrics data collection apparatus according to claim 2 , wherein the storage unit, calculating unit, extracting unit, and identifying unit are part of a personal computer.
5. The biometrics data collection apparatus according to claim 1 , wherein the predetermined condition is such that the identifying unit matches the acquired biometric data of said person to be identified with an identity when a plurality of biometric data of said person to be identified are contained in results extracted by the extracting unit.
6. The biometrics data collection apparatus of claim 1 , wherein the predetermined condition is such that the identifying unit matches the acquired biometric data of said person to be identified with an identity when all of the stored biometric data of said person to be identified are contained in results extracted by the extracting unit.
7. The biometric data collection apparatus of claim 1 , wherein the predetermined condition is such that the identifying unit matches the acquired biometric data of said person to be identified with an identity when the stored biometric data of said person to be identified have the highest occupation proportion in results extracted by the extracting unit.
8. The biometric data collection apparatus of claim 1 , wherein the predetermined condition is such that the identifying unit matches the acquired biometric data of said person to be identified with an identity when a predetermined number of stored biometric data of said person to be identified are contained in results extracted by the extracting unit.
9. The biometrics data collation apparatus of claim 1 ,
wherein the acquired biometrics data comprises face images of the person to be identified and the biometrics data acquiring unit comprises a face image acquiring unit for acquiring face images of the person to be identified,
wherein the stored biometrics data comprises a plurality of face images and the storage unit comprises a face image storage unit in which a plurality of different face images for each person of a plurality of persons who are collation targets are stored in advance in such a manner as to be associated with an identity of each person of said plurality of persons,
wherein the calculating unit comprises a face image calculating unit for calculating collation degree data obtained by comparing the acquired face images of said person to be identified with the stored face images, and
wherein the identifying unit comprises a face image identifying unit responsive to said extracting unit for matching the acquired face images of said person to be identified with an identity based on a predetermined condition relating to the quantity of face images of the person to be identified which are contained in results extracted by the extracting unit.
10. The biometrics data collation apparatus of claim 9 , wherein the predetermined condition is such that the face image identifying unit matches the acquired face images of said person to be identified with an identity when a plurality of stored face images of said person to be identified are contained in results extracted by the extracting unit.
11. The biometrics data collation apparatus of claim 9 , wherein the predetermined condition is such that the face image identifying unit matches the acquired face images of said person to be identified with an identity when all of the stored face images of said person to be identified are contained in results extracted by the extracting unit.
12. The biometrics data collation apparatus of claim 9 , wherein the predetermined condition is such that the face image identifying unit matches the acquired face images of said person to be identified with an identity when the stored face images of said person to be identified have the highest occupation proportion in results extracted by the extracting unit.
13. The biometrics data collation apparatus of claim 9 , wherein the predetermined condition is such that the face image identifying unit matches the acquired face images of said person to be identified with an identity when a predetermined number of stored face images of said person to be identified are contained in results extracted by the extracting unit.
