Embodiment Construction

[0057] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0058] The modeling method of Chinese Tang Dynasty style ancient building of the present invention, at first with the ancient building model layering based on point cloud, its similar layer clustering, obtains the different components of ancient building; Then utilize the symmetry of ancient building to ancient building Different components of different components are filled with missing data; straight lines and circles are extracted by Hough transform and least square method to realize elementary analytical surface reconstruction; then according to the characteristics of each layer point, the same point is selected for each layer, and according to the positional relationship of coordina...

Abstract

The modeling method of Tang Dynasty-style ancient buildings in China first layers the ancient building models based on point clouds, and clusters their similar layers to obtain different components of ancient buildings; then uses the symmetry of ancient buildings to model different components Fill in the missing data; extract straight lines and circles by Hough transform and least square method to realize elementary analytical surface reconstruction; then according to the characteristics of each layer point, select the same point for each layer, and form a quadrilateral mesh model according to the positional relationship of coordinates , to realize the reconstruction of free-form surfaces; finally, the realistic rendering of ancient buildings is realized by the method of texture mapping.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional visualization and mathematical modeling of computer graphics, and relates to a modeling method of a three-dimensional point cloud Chinese Tang Dynasty-style ancient building. Background technique [0002] The traditional 3D modeling of houses is mainly realized based on a set of picture information. For example, a 3D house modeling method based on multiple unordered photos designed by Sudipta et al. The viewpoint images of viewpoints are synthesized into new viewpoints and matched to build a 3D model of the entire object. This method effectively avoids the geometric complexity existing in the real scene, but the recovered object model lacks accurate geometric information and three-dimensional information, and the display effect of some corners of the house is not ideal, and it lacks a real three-dimensional sense. The modeling method is generally suitable for the field of virtual roamin...
