Image recognition based on augmented reality

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• submitting, by an augmented reality device and to a server, user information of a user using the augmented reality device;
• receiving, at the augmented reality device and from the server, a picture feature sample sub-library corresponding to the user information, wherein the picture feature sample sub-library is generated by the server based on screening out picture feature samples associated with the user information from a preset picture feature sample library;
• and
• performing, by the augmented reality device and during image scanning of a real-world environment of the user, image recognition of images scanned from the real-world environment by comparing the scanned images to picture features in the picture feature sample sub-library.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• submitting, by an augmented reality device and to a server, user information of a user using the augmented reality device;
• receiving, at the augmented reality device and from the server, a picture feature sample sub-library corresponding to the user information, wherein the picture feature sample sub-library is generated by the server based on screening out picture feature samples associated with the user information from a preset picture feature sample library;
• and
• performing, by the augmented reality device and during image scanning of a real-world environment of the user, image recognition of images scanned from the real-world environment by comparing the scanned images to picture features in the picture feature sample sub-library.
