Abstract

Claims (35)

1. An object comparison method, comprising:

acquiring, in response to a selection operation of at least two objects in an object list, corresponding object information according to identifiers of the at least two objects;

performing, on the basis of each object information, three-dimensional model information rendering to obtain three-dimensional model information of each of the objects; and

receiving image information of a real scenario to construct three-dimensional reconstruction information of the real scenario, and superimposing the three-dimensional model information of each of the objects onto the three-dimensional reconstruction information for display and comparison,

wherein the object information includes a three-dimensional resource and an information digest value;

the step of performing, on the basis of each object information, three-dimensional model information rendering further comprises:

processing, using an information digest algorithm, the three-dimensional resource of each of the objects to obtain a first information digest value; and

performing, on the basis of each of the three-dimensional resources, three-dimensional model information rendering if the information digest value is the same as the corresponding first information digest value.

2. The method of claim 1 , wherein the object information further includes a three-dimensional resource download address;

after the obtainment of the first information digest value, the step further comprises:

performing, on the basis of the three-dimensional resource download address in the object information, a three-dimensional resource download if the information digest value is different from the corresponding first information digest value;

processing, using the information digest algorithm, the downloaded three-dimensional resources to obtain a second information digest value; and

performing, using the downloaded three-dimensional resources, three-dimensional model information rendering if the information digest value is the same as the corresponding second information digest value.

3. The method of claim 2 , wherein the step of superimposing the three-dimensional model information of each of the objects onto the three-dimensional reconstruction information for display and comparison comprises:

determining, in accordance with a predetermined relative spatial position relationship in the three-dimensional reconstruction information, a storage position of each three-dimensional model information to superimpose each three-dimensional model information onto the three-dimensional reconstruction information at the corresponding storage position for display.

4. The method of claim 1 , wherein the construction of three-dimensional reconstruction information of the real scenario comprises:

determining, in a manner of a three-dimensional vision coordinate system, three-dimensional coordinate values of respective pixels in the image information to construct the three-dimensional reconstruction information on the basis of the three-dimensional coordinate values.

5. The method of claim 4 , wherein the step of superimposing the three-dimensional model information of each of the objects onto the three-dimensional reconstruction information for display and comparison comprises:

determining, in accordance with a predetermined relative spatial position relationship in the three-dimensional reconstruction information, a storage position of each three-dimensional model information to superimpose each three-dimensional model information onto the three-dimensional reconstruction information at the corresponding storage position for display.

6. The method of claim 1 , wherein the step of superimposing the three-dimensional model information of each of the objects onto the three-dimensional reconstruction information for display and comparison comprises:

determining, in accordance with a predetermined relative spatial position relationship in the three-dimensional reconstruction information, a storage position of each three-dimensional model information to superimpose each three-dimensional model information onto the three-dimensional reconstruction information at the corresponding storage position for display.

7. A non-transitory computer-readable storage medium, on which a computer program is stored, wherein the program, when executed by a processor, implements the method of claim 1 .

8. An object comparison apparatus, comprising:

a processor, wherein the processor is configured to performing:

acquiring, in response to a selection operation of at least two objects in an object list, corresponding object information according to identifiers of the at least two objects;

performing, on the basis of each object information, three-dimensional model information rendering to obtain three-dimensional model information of each of the objects; and

receiving image information of a real scenario to construct three-dimensional reconstruction information of the real scenario, and superimposing the three-dimensional model information of each of the objects onto the three-dimensional reconstruction information for display and comparison,

wherein the object information includes a three-dimensional resource and an information digest value;

the step of performing, on the basis of each object information, three-dimensional model information rendering further comprises:

processing, using an information digest algorithm, the three-dimensional resource of each of the objects to obtain a first information digest value; and

performing, on the basis of each of the three-dimensional resources, three-dimensional model information rendering if the information digest value is the same as the corresponding first information digest value.

9. An electrode device, comprising:

one or more processors; and

a storage means for storing one or more programs,

the one or more programs, when executed by the one or more processors, causing the one or more processors to implement the method of claim 1 .
