Three-dimensional design scene portrait construction method, electronic equipment and storage medium

The invention provides a three-dimensional design scene portrait construction method, which comprises the following steps of: acquiring offline design data and real-time design data in a three-dimensional design scene, and fusing the acquired two parts of design data; preprocessing three-dimensional space information of the three-dimensional design scene and design material information in the scene; constructing a double-tower model, mapping the feature representation of the three-dimensional scene and the design material representation in the same space by using a double-tower model structure, and performing feature alignment; feature description is carried out on the three-dimensional scene and feature extraction is carried out on the design material according to the double-tower model structure; and introducing the feature vectors subjected to feature description and feature extraction into recall and sorting stages of recommendation and search, and carrying out personalized recommendation and search resul
