Digital twin city space coordinate system implementation method and device based on unreal engine and storage medium

Abstract

The invention discloses a digital twin city space coordinate system implementation method based on an unreal engine, and the method comprises the steps: mapping the spherical coordinate data of a newly constructed equilateral triangle coverage area into a plane space coordinate system of the unreal engine through an equilateral triangle in a coverage range of a spherical space system; and the spherical space system being completely covered by the constructed equilateral triangle. By means of the coordinate system implementation method, a traditional gis spherical system can be mapped to a plane space coordinate system based on an unreal engine through a triangular section algorithm, and correct positioning of the spherical coordinate system can be achieved in the digital twin city technology of the unreal engine; the coordinate system established by adopting the method is rapid and variable in precision, and the precision can be changed at will according to different technical applications.

Description

technical field [0001] The present invention relates to the technical field of digital twins, in particular to a method, device and storage medium for realizing a digital twin city spatial coordinate system based on Unreal Engine. 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, there is no technology that can perfectly solve all the problems in the "digital twin". In the current technical environment, the game industry and the GIS industry are It is most likely to become the leading industry of digital twins. However, whoever can take the lead in stepping out of the framework of its own field, integrate its own technical advantages from a more macro level, and put it into more diverse application sc...

AI Technical Summary

Problems solved by technology

[0005] But as far as the current existing technology is concerned, traditional spherical coordinates cannot be used directly in Unreal. Due to the particularity of spherical coordinates, the existing positioning methods of spherical coordinates in Unreal Engine's plane coordinate system usually cause large errors. Accurate positioning of spherical coordinates in Unreal Engine's plane coordinate system cannot be achieved
