Knowledge graph-based 3D modeling method and system thereof

The invention relates to a knowledge graph-based 3D modeling method, and the method comprises the following steps: building a data hotspot library, and carrying out the modeling management of 3D model information; establishing a 3D model association network, and obtaining a relation degree between devices in the 3D model system; establishing a 3D model matching network, and obtaining data hotspots corresponding to the 3D model; and analyzing and evaluating the 3D model matching network by comparing the feature information of the reality equipment with the obtained feature information of the 3D model. According to the method disclosed by the invention, the 3D models in the knowledge graph are subjected to hierarchical management, and the 3D models in the knowledge graph can be quickly queried through the received data hotspot information; by adopting the 3D model association network, the association degree among the devices in the system can be quickly obtained, and the 3D model obtained in the model matching
