Image-based 3d model search and retrieval

A computer-implemented method comprising:

• receiving a search query;
• selecting multiple, different two-dimensional views of a three-dimensional model that is identified as responsive to the search query;
• generating an image query that includes a query term that matches a query term of the search query;
• obtaining images that are identified as response to the image query that includes the query term that matches the query term of the search query;
• generating a respective score for each one of the multiple, different two-dimensional views based on one or more similarities between the views and the images that are identified as response to the image query that includes the query term that matches the query term of the search query;
• selecting a particular two-dimensional view of the three-dimensional model from among the multiple, different two-dimensional views as a representative view of the three-dimensional model based on the scores of the multiple, different two-dimensional views;
• and
• providing the representative view of the three-dimensional model in response to the search query.

A system comprising:

• one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• receiving a search query;
• selecting multiple, different two-dimensional views of a three-dimensional model that is identified as responsive to the search query;
• generating an image query that includes a query term that matches a query term of the search query;
• obtaining images that are identified as response to the image query that includes the query term that matches the query term of the search query;
• generating a respective score for each one of the multiple, different two-dimensional views based on one or more similarities between the views and the images that are identified as response to the image query that includes the query term that matches the query term of the search query;
• selecting a particular two-dimensional view of the three-dimensional model from among the multiple, different two-dimensional views as a representative view of the three-dimensional model based on the scores of the multiple, different two-dimensional views;
• and
• providing the representative view of the three-dimensional model in response to the search query.

A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

• receiving a search query;
• selecting multiple, different two-dimensional views of a three-dimensional model that is identified as responsive to the search query;
• generating an image query that includes a query term that matches a query term of the search query;
• obtaining images that are identified as response to the image query that includes the query term that matches the query term of the search query;
• generating a respective score for each one of the multiple, different two-dimensional views based on one or more similarities between the views and the images that are identified as response to the image query that includes the query term that matches the query term of the search query;
• selecting a particular two-dimensional view of the three-dimensional model from among the multiple, different two-dimensional views as a representative view of the three-dimensional model based on the scores of the multiple, different two-dimensional views;
• and
• providing the representative view of the three-dimensional model in response to the search query.
