Abstract

The embodiment of the invention provides a monomer method and system for a three-dimensional building model. The method comprises the following steps that: according to the building information modelof a target building, obtaining the white model of the target building; independently processing the inclined remote-sensing image of each surface of the target building to obtain the front view texture image of each surface of the target building; and according to the front view texture image of each surface of the target building, rendering the white model of the target building to obtain the monomer model of the target model. By use of the monomer method and system, which is provided by the embodiment of the invention, for the three-dimensional building model, the geometrical information ofthe building information model data is organically combined with the texture information of the remote sensing image, so that on one hand, the monomer of the three-dimensional building model can be quickly and conveniently realized, efficiency is high, on the other hand, independent surface features in the three-dimensional geographic information can be effectively identified and distinguished, and the monomer accuracy of the three-dimensional building model can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of geographic information, and in particular to a method and system for singulating three-dimensional building models. Background technique [0002] The goal of monomerization is to build a 3D object model. The core is to realize the independence of the model in the 3D scene and to be able to efficiently manage and analyze it while taking efficiency into consideration. At present, in the fine application field of 3D geographic information system (Geographic Information System or Geo-Information system, referred to as GIS), there are mainly three single modeling methods, namely traditional manual modeling, 3D laser scanning modeling technology and oblique photogrammetry Automated modeling techniques. For these three methods, there are different monolithic solutions. Generally speaking, the current single method tends to two extreme directions: one is from geometric model construction t...
