Abstract

The present disclosure provides a method and for acquiring text data of a trademark image, a computer device and a non-transitory computer readable storage medium. The method includes the followings. A trademark database including one or more mappings among trademark feature information, trademark description information and trademark text information is established. A to-be-processed image including image description information is acquired. Trademark feature information corresponding to the to-be-processed image is determined. The trademark text information corresponding to the trademark feature information as the text data of the trademark image corresponding to the to-be-processed image according to the one or more mappings in the trademark database when the trademark description information corresponding to the trademark feature information corresponding to the to-be-processed image is contained in the image description information corresponding to the to-be-processed image.

First claim

What is claimed is:

1. A method for acquiring text data of a trademark image, comprising:
x, establishing a trademark database, wherein the trademark database comprises one or more mappings among trademark feature information, trademark description information and trademark text information;
wherein the method further comprises:
a, acquiring a to-be-processed image from a page, and determining image description information of the to-be-processed image from page information of the page, wherein the image description information comprises text information contained in the page information;
b, determining trademark feature information corresponding to the to-be-processed image; and
c, according to the one or more mappings in the trademark database, when trademark description information corresponding to the trademark feature information corresponding to the to-be-processed image is contained in the image description information, determining trademark text information corresponding to the trademark feature information corresponding to the to-be-processed image as text data of the trademark image corresponding to the to-be-processed image.

2. The method according to claim 1 , wherein step a further comprises:
determining one or more similar images corresponding to the to-be-processed image according to the to-be-processed image; and
determining the image description information of the to-be-processed image according to the image description information corresponding to the one or more similar images.

3. The method according to claim 1 , wherein step b comprises:
performing an object detection on the to-be-processed image, to determine a trademark position on the to-be-processed image; and
determining the trademark feature information corresponding to the trademark position.

4. The method according to claim 3 , wherein step c comprises:
according to the one or more mappings in the trademark database, when the trademark description information corresponding to the trademark feature information corresponding to the to-be-processed image is contained in the image description information, determining the trademark text information corresponding to the trademark feature information corresponding to the to-be-processed image as the text data of the trademark image corresponding to the trademark position on the to-be-processed image.

5. The method according to claim 1 , further comprising:
r, determining the trademark image corresponding to the to-be-processed image and the text data corresponding to the trademark image as training data.

6. The method according to claim 5 , wherein step r comprises:
only when the text data of the trademark image corresponding to the to-be-processed image is a nonempty set, determining the trademark image corresponding to the to-be-processed image and the text data corresponding to the trademark image as the training data.

7. A computer device, comprising:
one or more processors;
a memory, configured to store one or more computer programs;
wherein when the one or more computer programs are executed by the one or more processors, a method for acquiring text data of a trademark image is executed by the one or more processors, the method comprises:
x, establishing a trademark database, wherein the trademark database comprises one or more mappings among trademark feature information, trademark description information and trademark text information;
a, acquiring a to-be-processed image from a page, and determining image description information of the to-be-processed image from page information of the page, wherein the image description information comprises text information contained in the page information;
b, determining trademark feature information corresponding to the to-be-processed image; and
c, according to the one or more mappings in the trademark database, when trademark description information corresponding to the trademark feature information corresponding to the to-be-processed image is contained in the image description information, determining trademark text information corresponding to the trademark feature information corresponding to the to-be-processed image as text data of the trademark image corresponding to the to-be-processed image.

8. The computer device according to claim 7 , wherein step a further comprises:
determining one or more similar images corresponding to the to-be-processed image according to the to-be-processed image; and
determining the image description information of the to-be-processed image according to the image description information corresponding to the one or more similar images.

9. The computer device according to claim 7 , wherein step b comprises:
performing an object detection on the to-be-processed image, to determine a trademark position on the to-be-processed image; and
determining the trademark feature information corresponding to the trademark position.

10. The computer device according to claim 9 , wherein step c comprises:
according to the one or more mappings in the trademark database, when the trademark description information corresponding to the trademark feature information corresponding to the to-be-processed image is contained in the image description information, determining the trademark text information corresponding to the trademark feature information corresponding to the to-be-processed image as the text data of the trademark image corresponding to the trademark position on the to-be-processed image.

11. The computer device according to claim 7 , further comprising:
r, determining the trademark image corresponding to the to-be-processed image and the text data corresponding to the trademark image as training data.

12. The computer device according to claim 11 , wherein step r comprises:
only when the text data of the trademark image corresponding to the to-be-processed image is a nonempty set, determining the trademark image corresponding to the to-be-processed image and the text data corresponding to the trademark image as the training data.

13. A non-transitory computer readable storage medium, having computer codes stored therein, when the computer codes are executed, a method for acquiring text data of a trademark image is executed, wherein the method includes:
x, establishing a trademark database, wherein the trademark database comprises one or more mappings among trademark feature information, trademark description information and trademark text information;
wherein the method further comprises:
a, acquiring a to-be-processed image from a page, and determining image description information of the to-be-processed image from page information of the page, wherein the image description information comprises text information contained in the page information;
b, determining trademark feature information corresponding to the to-be-processed image; and
c, according to the one or more mappings in the trademark database, when trademark description information corresponding to the trademark feature information corresponding to the to-be-processed image is contained in the image description information, determining trademark text information corresponding to the trademark feature information corresponding to the to-be-processed image as text data of the trademark image corresponding to the to-be-processed image.

14. The non-transitory computer readable storage medium according to claim 13 , wherein step a further comprises:
determining one or more similar images corresponding to the to-be-processed image according to the to-be-processed image; and
determining the image description information of the to-be-process
