Building model monomerization method, device and storage medium

The embodiment of the invention provides a building model monomerization method, a device and a storage medium. The method comprises the steps of generating a monomerization model framework of a building according to two-dimensional vector data of the building and an oblique photogrammetry model, wherein the oblique photogrammetry model comprises a three-dimensional model and texture information of the building; and mapping the texture information of the building in the oblique photogrammetry model to the monomer model framework, and generating a monomer model of the building. According to the method provided by the embodiment of the invention, the monomer model framework is generated through the two-dimensional vector data of the building and the oblique photogrammetry model, and texture mapping is performed on the monomer model framework to generate the monomer model of the building, so that attributes and management can be independently given to the building model; the large-range digital city rendering re
