Method and device for processing image, and storage medium

A device for processing image, comprising:

• a processor;
• and
• a memory for storing computer executable instructions;
• wherein the processor is configured to execute the computer executable instructions in the memory to perform following:
• acquiring a first image and a first virtual object, wherein the first virtual object has the first image comprises a target object, the first virtual object has a corresponding relationship with a preset standard model, and the preset standard model is obtained by a three-dimensional reconstruction algorithm and a sample image;
• determining a target model by reconstructing the target object in three-dimension based on the three-dimensional reconstruction algorithm, wherein the target model corresponds to the target object;
• obtaining first preset vertexes on a first mesh model corresponding to the target model by transforming third preset vertexes on a third mesh model corresponding to the standard model through a first mapping between the target model and the standard model;
• obtaining control information based on a transformation matrix of the first preset vertexes in local coordinate systems relative to a world coordinate system;
• obtaining a second virtual object, by processing the first virtual object based on the control information;
• wherein the second virtual object is matched with the target object, and
• generating a second image based on the second virtual object, wherein the second image comprise the target object fitted with the second virtual object.

A nonvolatile storage medium, configured to store computer executable instructions, when the computer executable instructions are executed by a processor of an electronic apparatus, following is implemented:

• acquiring a first image and a first virtual object, wherein the first image comprises a target object, the first virtual object has a corresponding relationship with a preset standard model, and the preset standard model is obtained by a three-dimensional reconstruction algorithm and a sample image;
• determining a target model by reconstructing the target object in three-dimension based on the three-dimensional reconstruction algorithm, wherein the target model corresponds to the target object;
• obtaining first preset vertexes on a first mesh model corresponding to the target model by transforming third preset vertexes on a third mesh model corresponding to the standard model through a first mapping between the target model and the standard model;
• obtaining control information based on a transformation matrix of the first preset vertexes in local coordinate systems relative to a world coordinate system;
• obtaining a second virtual object, by processing the first virtual object based on the control information, wherein the second virtual object is matched with the target object, and
• generating a second image based on the second virtual object, wherein the second image comprise the target object fitted with the second virtual object.
