Embodiment Construction

[0043] Below we will further illustrate the present invention in conjunction with accompanying drawing and specific example:

[0044] Such as figure 1 As shown, the process of establishing the realistic and theoretical interactive model of architectural special-shaped surfaces is mainly divided into six steps: namely, 3D laser scanning, point cloud data processing, triangulation modeling, surface reconstruction and migration, theoretical model establishment, and production put up.

[0045] The following describes its implementation in conjunction with a specific example:

[0046] This example is a villa designed by a Dutch designer for a high-end villa area in Beijing. Because the design concept is relatively advanced, the villa adopts a large number of spatial and curved surface structures. figure 2 It is one of the villas in the villa area. image 3It is one of the complex special-shaped surfaces with a length of 7.5m and a height of 3m. After the curved surface is buil...

Abstract

The invention relates to a method for building a new theoretical model based on an existing special-shaped curved surface in reality, especially a method for building a new three-dimensional model on the special-shaped curved surface of a large-scale building. The method comprises the steps: obtaining three-dimensional point cloud data through scanning the special-shaped curved surface in reality; generating a triangulation network model of the special-shaped curved surface through the processing of point cloud data; reconstructing a new NURBS smooth curved surface on the basis of the triangulation network model, and carrying out the offsetting of the new NURBS smooth curved surface; constructing a theoretical model on the offset new NURBS smooth curved surface; and finally generating a new model which can be machined and installed on the existing special-shaped curved surface.

Description

technical field [0001] The invention relates to a method for establishing a new theoretical model based on an existing special-shaped curved surface in reality, especially for establishing a new three-dimensional model on a large-scale architectural special-shaped curved surface. [0002] technical background [0003] In engineering, the surface modeling of products is basically composed of the following two types: the first type is composed of elementary analytical surfaces such as plane, spherical surface, cylindrical surface, and conical surface. Because of its regular shape and easy processing, many machinery, construction, The shapes of industrial and other products belong to this category; the second category is not composed of elementary analytical surfaces, but is composed of curved surfaces that change freely in complex ways, that is, so-called special-shaped surfaces, which often appear in automobiles, airplanes, ships, and special-shaped buildings. .
