Embodiment Construction
[0022] Such as figure 1A detailed system flow diagram for 3D model retrieval is shown in Fig. The technology of the present invention can realize the system function of three-dimensional model network search. The user inputs a 3D model in the query interface and plans to search for all similar models of the model. The retrieval system sends the retrieval request of the model to the search engine through the network, and the search engine responds by sending the retrieved 3D models that meet the requirements to users, and sort the 3D models according to the degree of similarity. The specific process is that when the system receives the retrieval request of the 3D model sent by the client user, it first obtains the feature vector of the 3D model through a feature extraction algorithm. The feature vector can uniquely express a 3D model and has a high degree of discrimination, which can It is different from other 3D models. Feature extraction algorithms analyze shape orientatio...
