Abstract
The present invention relates to a high-accuracy automatic 3D modeling method for complex buildings, comprising the steps of: transforming the complex building to a complex polygon by using the topological structure of polygons firstly, transforming complex polygons to a set of triangles which are seamlessly spliced by programming an algorithm and accomplishing high-accuracy automatic 3D modeling of buildings.
Claims11
A high-accuracy automatic 3D modeling method for complex buildings, comprising the steps of:
- reading and preprocessing data of a building;
- extracting information for modeling from the preprocessed data;
- and
- modeling a main body and a roof of the building by using the information for modeling acquired in the extracting step;
- wherein the main body of the building is modeled based on plane coordinates and elevation data of a boundary of the building acquired from the information for modeling;
- wherein an order in which nodes of the boundary of the building are plotted in the information for modeling is rearranged and then input to a 3D engine for modeling;
- characterized in that the roof is modeled by determining the shape of the roof based on the plane coordinates of the boundary of the roof acquired from the information for modeling, processing the boundary of the roof based on the determination, and modeling the roof based on the shape of the roof and the elevation data without addition of nodes of the boundary.
