The application discloses a three-dimensional building modeling method, a device and a three-dimensional building group modeling method. The three-dimensional building modeling method includes: acquiring oblique photographic data of building units; acquiring each semantic component of the building unit; acquiring multiple preset primitive component databases, one preset primitive component database corresponding to a semantic component, each The preset primitive component database includes a plurality of preset primitive components; for each semantic component, the following operations are performed: according to the semantic component, a corresponding preset primitive component is obtained as the primitive component to be modeled; Element components are modeled to form a building model. This application uses the preset primitive component database to obtain the preset primitive components that are basically the same as the semantic components corresponding to the oblique photography data as the primitive components to be modeled, which overcomes the problems caused by directly modeling with oblique photography data. Influenced by factors such as tree occlusion in the original grid, missing key parts of the grid, and noise.
Description
technical field [0001] The present application relates to the technical field of architectural modeling, and in particular to a three-dimensional architectural modeling method, a three-dimensional architectural modeling device, and a three-dimensional architectural group modeling method. Background technique [0002] The traditional oblique photography 3D reconstruction model is a dense point cloud or a dense mesh (mesh). The core is multi-eye reconstruction, the recognition of camera pose and the matching of feature points. The reconstruction results include: geometry and texture. Due to methodological flaws, it is a low-quality reconstruction. Disadvantages include geometrically noisy meshes, distorted textures, lack of materials, no semantics, etc. [0003] Therefore, it is desirable to have a technical solution to solve or at least alleviate the above-mentioned deficiencies of the prior art. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is t...
