Title:
METHOD AND APPARATUS FOR ESTABLISHING MODEL, ELECTRONIC DEVICE, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/021309
Kind Code:
A1
Abstract:
A method and apparatus for establishing a model and a computer readable storage medium. The method comprises: obtaining description accuracy information of a first grid display layer of a scene three-dimensional model for a scene (101); determining a target geometric error of a second grid display layer of the scene three-dimensional model according to the description accuracy information (102); performing grid simplification processing on multiple grid surfaces in the first grid display layer to obtain new grid surfaces (103); and using the newly formed grid surfaces as the second grid display layer of the scene three-dimensional model for storage (104). According to the method, in the process of obtaining the grid display layers having decreasing levels of detail, the process of calculation of a perfect display layer is eliminated and calculation pressure is reduced; moreover, because more accurate physical size information and/or deviation information of sampling points are used for determining the target geometric error, the problem that when a global hausdorff distance is used as the geometric error, the level index of detail of the grid display layer is too large, thereby causing the subsequent rendering accuracy to decrease is solved.
