Three-dimensional model construction method and device

Abstract

The invention provides a three-dimensional model construction method and device, and solves the problems of tedious work and low efficiency of manual configuration of spatial point locations in a three-dimensional space. The three-dimensional model construction method comprises the steps that outdoor position information of first objects in a three-dimensional space is obtained based on the mapping relation between longitude and latitude data of a geographic information system and coordinate data in the three-dimensional space, and the first objects comprise buildings; acquiring a preset building reference map corresponding to the building, and acquiring indoor position information of each second object in the building relative to the building based on the preset building reference map; obtaining object position information of each second object in the three-dimensional space based on the outdoor position information of each first object in the three-dimensional space and the indoor position information of each second object relative to the building; and constructing a three-dimensional model based on the outdoor position information of each first object in the three-dimensional space and the object position information of each second object in the three-dimensional space.

Description

technical field [0001] The invention relates to the technical field of spatial positioning, in particular to a method and device for building a three-dimensional model. Background technique [0002] With the development of science and technology, digital twin technology has gradually evolved from a theoretical concept to a stage of technical application. However, at present, there are many technical problems to be solved in the mapping from the physical world to the virtual world. At present, no technology can perfectly solve all the problems existing in the "digital twin". [0003] The realization of space physical coordinate technology in the game engine is an inevitable trend in the development of digital twins. The core advantage of the game engine lies in its powerful "scene expression". On the one hand, through real-time dynamic rendering, it can build rich and detailed scene performance, so as to better restore the world we "see"; on the other hand, the powerful The...
