Abstract

Methods, apparatus, and systems for information identification are provided. A card image of a pre-set collection area is photographed and obtained, when a request event for information identification is detected. Edge-size information of the card image obtained by photographing is determined. A target area of the card image is marked according to the edge-size information. An image of the target area is extracted. Character shapes to be identified in the image of the target area is determined based on a pre-set character pattern library. A character corresponding to each character shape to be identified is identified according to each character shape to be identified that is determined and according to the character pattern library.

First claim

What is claimed is:

1. A method for information identification by a user terminal having at least a processor and a camera, comprising:
obtaining a card image by photographing of a collection area that is pre-set, when a request event for an information identification is detected, including:
obtaining a card type of a card to be identified designated by the user according to the request event of the information identification;
displaying, on a display screen of the user terminal, a photographing interface having the collection area pre-set with a designated shape and a designated edge-size based on the card type, the collection area being a sub-area from a detection area of the camera; and
when a request event for photographing is detected, obtaining the card image of the collection area by photographing with the camera;

determining edge-size information of the card image obtained by photographing, marking a target area of the card image according to the edge-size information; and extracting an image of the target area; and
determining character shapes to be identified in the image of the target area based on a pre-set character pattern library, and identifying a character corresponding to each character shape to be identified according to each character shape to be identified that is determined and according to the character pattern library.

2. The method according to claim 1 , wherein the step of determining the edge-size information of the card image and extracting the image of the target area includes:
determining the edge-size information of the card image obtained by photographing, and determining the card type corresponding to the card image according to the determined edge-size information;
obtaining location information of an identification area set by the card type, wherein the location information of the identification area includes location information of the identification area in a card with respect to an edge of the card; and
determining and marking the target area of the card image, and extracting the image of the target area, based on the location information of the identification area and the edge-size information.

3. The method according to claim 1 , wherein the step of determining the edge-size information of the card image and extracting the image of the target area includes:
determining the edge-size information of the card image obtained by photographing, and according to the edge-size information, determining the card type corresponding to the card image;
marking an area containing the embossed information as the target area of the card image based on a pixel characteristic of an embossed part pre-set in the image, when the card type indicates a card containing embossed information; and
extracting the image of the target area.

4. The method according to claim 3 , further including one or more steps selected from:
displaying an identified character; and
sending the identified character to a server corresponding to the payment application according to a payment application turned on by a user, when the identified character includes a characteristic for a bank card number.

5. The method according to claim 1 , further including:
receiving the card image obtained by photographing from a terminal;
determining the edge-size information of the card image obtained by photographing; marking the target area of the card image according to the edge-size information; and extracting the image of the target area; and
determining character shapes to be identified in the image of the target area based on the pre-set character pattern library; and according to each character shape to be identified that is determined and the character pattern library, identifying the character corresponding to each character shape to be identified.

6. A method for information identification, comprising:
obtaining, by a terminal having at least a processor and a camera, a card image by photographing of a collection area that is pre-set, and sending the card image obtained by photographing to a server having at least a processor, when a request event for an information identification is detected;
determining, by the server, edge-size information of the card image obtained by photographing when the server receives the card image, marking a target area of the card image according to the edge-size information, and extracting an image of the target area; and
determining, by the server, character shapes to be identified in the image of the target area based on a pre-set character pattern library; and identifying a character corresponding to each character shape to be identified, according to each character shape to be identified that is determined and according to the character pattern library;
wherein obtaining the card image further comprises:
obtaining a card type of a card to be identified designated by the user according to the request event of the information identification;
displaying, on a display screen of the user terminal, a photographing interface having the collection area pre-set with a designated shape and a designated edge-size based on the card type, the collection area being a sub-area from a detection area of the camera; and
when a request event for photographing is detected, obtaining the card image of the collection area by photographing with the camera.

7. The method according to claim 6 , further including one or more steps selected from:
returning, by the server, an identified character to the terminal;
displaying, by the terminal, the identified character; and
according to a payment application turned on by a user, sending, by the terminal, the identified character to the server corresponding to the payment application.

8. An apparatus for information identification, comprising:
a collecting module, configured to obtain a card image by photographing of a collection area that is pre-set, when a request event of an information identification is detected, including:
obtaining a card type of a card to be identified designated by the user according to the request event of the information identification;
displaying, on a display screen of the user terminal, a photographing interface having the collection area pre-set with a designated shape and a designated edge-size based on the card type, the collection area being a sub-area from a detection area of the camera; and
when a request event for photographing is detected, obtaining the card image of the collection area by photographing with the camera;

an extracting module, configured to determine edge-size information of the card image obtained by photographing; to mark a target area of the card image according to the edge-size information; and to extract an image of the target area; and
an identifying module, configured to determine character shapes to be identified in the image of the target area based on a pre-set character pattern library; and to identify a character corresponding to each character shape to be identified according to each character shape to be identified that is determined and according to the character pattern library.

9. The apparatus according to claim 8 , wherein the extracting module includes:
a first determining unit, configured to determine the edge-size information of the card image obtained by photographing, and according to the determined edge-size information, to determine the card type corresponding to the card image;
an obtaining unit, configured to obtain location information of an identification area set by the card type, wherein the location information of the identification area includes location information of the identification area in a card with respect to an edge of the card; and
a first extracting unit
