Abstract

The invention discloses a three-dimensional hollow model generation method based on a self-defined image. The method comprises the steps of connecting non-hollow areas of an input binary image; determining narrow areas of the non-hollow areas of the input binary image, establishing a narrow area set, and broadening and smoothing the narrow areas in the set, thereby forming the optimized binary image; mapping the optimized binary image as texture to a candidate area of a three-dimensional model through utilization of conformal parameterization method, and establishing a three-dimensional entity model; carrying out shell extraction on the three-dimensional entity model and carrying out hollowing according to a set image, thereby obtaining a three-dimensional hollow model; and carrying out stress detection on the established three-dimensional hollow model and carrying out optimization according to a detection result. According to the three-dimensional model obtained by the method, a geometrical shape of an input model is kept, and the hollow model which is generated according to the self-defined image, has artistic value and saves material is obtained.

Description

technical field [0001] The invention relates to a method for generating a three-dimensional hollow model based on a self-defined image. Background technique [0002] The three-dimensional hollow model is a digital model that hollows out the pattern that needs to be expressed on the model shell and retains the background on the basis of the three-dimensional model. Because the hollow art has the characteristics of prominent patterns and saving materials, it is widely used in the artistic processing of products in various fields, such as architectural decoration, furniture decoration, and utensil decoration. [0003] A binary image is a digital image with only two possible values ​​for each pixel. Black-and-white, B&W, and monochrome images are often used to represent binary images, but can also be used to represent any image that has only one sample value per pixel. [0004] Three-dimensional modeling technology has been developed for a long time and gradually matured. In t...
