Abstract

The invention provides a three-dimensional model construction method, device and equipment and a computer readable storage medium, and belongs to the technical field of three-dimensional modeling. The method comprises the steps that vector data of each object in a to-be-modeled area is obtained, and the vector data comprises attribute information and space information; based on the spatial information of each object in the to-be-modeled area, geometric structure body sub-models are generated, and one object corresponds to one geometric structure body sub-model; texture mapping processing is carried out on the geometric structure body sub-model of the target object by adopting mapping textures associated with attribute information of the target object, so that a three-dimensional model is obtained, and the to-be-modeled area comprises the target object; and the three-dimensional model is output. According to the invention, the modeling efficiency of three-dimensional modeling can be improved.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional modeling, in particular to a three-dimensional model construction method, device, equipment and computer-readable storage medium. Background technique [0002] There are many methods related to 3D modeling in the prior art, and representative methods include: using oblique photogrammetry technology to generate a real 3D model and using 3D modeling software to manually model. [0003] Among them, through oblique photogrammetry technology, it is necessary to use aerial photography devices to take multi-angle oblique photography of buildings, etc., so as to construct a surface model composed of continuous triangular nets based on the images obtained by oblique photography, and the model is not refined enough. And limited by the shooting angle, the density of buildings and automatic modeling technology, there will be problems of incomplete information acquisition. However, manual mo...
