Method for generating different types of height map control bas-relief model

Abstract

The invention relates to a method for generating a different-type height map control bas-relief model, and belongs to the technical field of computer graphics. According to the method, the generation of the digital bas-relief is realized by combining mask operation in image processing and a three-dimensional modeling technology, the mask operation is utilized to process an image to be processed, the image processing technology is fused, the heights of different parts of the to-be-generated relief are controlled, and a height map for controlling the relief generation effect is obtained; normal decomposition is performed by using rolling guide normal filtering based on a Gaussian mixture model, and curved surface reconstruction is performed by using a local adjustment and global reconstruction method based on SfG; and denoising smoothing processing is performed by using a Laplace operator and a bilateral filter, and finally generating bas-relief models with different height styles. According to the method, a bas-relief model with a clear contour and rich details is realized mainly by adjusting relevant parameters of detail features and structural features.

Description

technical field [0001] The invention belongs to the technical field of computer graphics and relates to a method for generating shallow relief models controlled by different types of height maps. The bas-relief generated by the invention can be used as the input of the computer-aided manufacturing equipment, and provides a new solution for the custom-made service of relief products. Background technique [0002] As a kind of artistic product, relief has its own unique form of expression and advantages in aesthetic expression. In contrast to high relief, in which elements of the scene are taken from the plane of the relief, relief has elements projected into a very narrow range of depths. Its spatial structure not only expresses three-dimensional shape, but also has two-dimensional shape. It occupies a small space, but it is extremely rich in detail information. It is an art form that can provide more information for viewers in a limited space. Reliefs can be appreciated as...
