Building-oriented data fusion method and equipment

The invention provides a building-oriented data fusion method and equipment. The building-oriented data fusion method comprises the following steps: acquiring multi-modal data of a building in a target geographic area at different times through a crawler program; for the multi-modal data at each time, obtaining triple data of each type of data; according to the triple data of each type of data, carrying out attribute alignment processing, and constructing a building knowledge graph corresponding to the building entity identifier; obtaining an alignment entity pair, and according to the alignment entity pair, performing fusion processing on the knowledge graph of the building to obtain a target knowledge graph for the building after fusion processing; and constructing a multi-level index building database according to the target knowledge maps of the building at different times. According to the method provided by the invention, multi-dimensional data fusion of the building is realized, time sequence predictio
