METHOD AND SYSTEM FOR FACILITATING FACIAL-RECOGNITION-BASED PAYMENT SYSTEM WITH MULTIPLE VIEWING ANGLES AND REDUCED MISPAYMENT RISK
One embodiment described herein provides a system for facilitating processing payment based on facial recognition. During operation, the system obtains, from a first camera, visual information associated with a payment scene comprising bodies of one or more customers. In response to receiving a payment-initialization command, the system obtains, from a second camera, an image comprising faces of the one or more customers. The system identifies, based on the visual information associated with the payment scene, a body that is performing a movement to enter the payment-initialization command, and identifies a face in the image obtained from the second camera based on user-identification information associated with the identified body. The system then extracts facial information from the identified face, thereby facilitating a transaction of the payment based on the extracted facial information.
1 . A computer-implemented method for facilitating processing a payment based on facial recognition, the method comprising:
obtaining, from a first camera, visual information associated with a payment scene which includes one or more customers;
in response to receiving a payment-initialization command, obtaining, from a second camera, an image comprising faces of the one or more customers;
identifying, based on the visual information associated with the payment scene, a body performing a movement while entering the payment-initialization command;
identifying a face in the image obtained from the second camera based on user-identification information associated with the identified body; and
extracting facial information from the identified face, thereby facilitating a transaction of the payment based on the extracted facial information.
2 . The method of claim 1 , wherein the visual information associated with the payment scene comprises a video or a still image.
3 . The method of claim 1 , wherein identifying the body performing the movement comprises:
receiving timing information associated with the payment-initialization command; and
analyzing the visual information based on the received timing information.
4 . The method of claim 3 , wherein analyzing the visual information comprises one or more of:
recognizing a posture of the body;
recognizing a movement of a portion of the body; and
recognizing a position of the body or the portion of the body.
5 . The method of claim 1 , wherein the user-identification information comprises one or more of:
body posture information;
position information;
partial facial information; and
apparel information.
6 . The method of claim 1 , wherein identifying the face comprises:
extracting, from each face included in the image, user-identification information associated with each face; and
comparing the user-identification information associated with each face to the user-identification information associated with the identified body.
7 . The method of claim 6 , further comprising:
in response to failing to find a match or finding multiple matches between the user-identification information associated with each face and the user-identification information associated with the identified body, displaying an error message.
8 . The method of claim 1 , further comprising:
identifying a customer based on the extracted facial information;
identifying an account corresponding to the identified customer; and
completing the transaction using the identified account.
9 . The method of claim 1 , wherein the payment-initialization command comprises one or more of:
a tapping on a touchscreen display;
a keystroke on a keyboard; and
a press of a physical button.
10 . The method of claim 1 , wherein a field of view (FOV) of the first camera is greater than a FOV of the second camera.
11 . An apparatus for processing a payment based on facial recognition, comprising:
an input module configured to receive a payment-initialization command;
a first camera configured to obtain visual information associated with a payment scene which includes one or more customers;
a second camera configured to obtain an image comprising faces of the one or more customers, in response to the input module receiving the payment-initialization command;
a body-identification module configured to identify, based on the visual information associated with the payment scene, a body performing a movement while entering the payment-initialization command;
a face-identification module configured to identify a face in the image obtained by the second camera based on user-identification information associated with the identified body; and
a facial-information-extraction module configured to extract facial information from the identified face, thereby facilitating a transaction of the payment based on the extracted facial information.
12 . The apparatus of claim 11 , wherein the visual information associated with the payment scene comprises a video or a still image.
13 . The apparatus of claim 11 , wherein, while identifying the body performing the movement, the body-identification module is configured to:
receive timing information associated with the payment-initialization command; and
analyze the visual information based on the received timing information.
14 . The apparatus of claim 13 , wherein analyzing the visual information comprises one or more of:
recognizing a posture of the body;
recognizing a movement of a portion of the body; and
recognizing a position of the body or the portion of the body.
15 . The apparatus of claim 11 , wherein the user-identification information comprises one or more of:
body posture information;
position information;
partial facial information; and
apparel information.
16 . The apparatus of claim 11 , wherein, while identifying the face, the face-identification module is configured to:
extract, from each face included in the image, user-identification information associated with each face; and
compare the user-identification information associated with each face to the user-identification information associated with the identified body.
17 . The apparatus of claim 16 , further comprising a display configured to:
in response to the face-identification module failing to find a match or finding multiple matches between the user-identification information associated with each face and the user-identification information associated with the identified body, display an error message.
18 . The apparatus of claim 11 , further comprising:
a customer-identification module configured to identify a customer based on the extracted facial information;
an account-identification module configured to identify an account corresponding to the identified customer; and
a transaction module configured to complete the transaction using the identified account.
19 . The apparatus of claim 11 , wherein the payment-initialization command comprises one or more of:
a tapping on a touchscreen display;
a keystroke on a keyboard; and
a press of a physical button.
20 . The apparatus of claim 11 , wherein a field of view (FOV) of the first camera is greater than a FOV of the second camera.
