Urban macroscopic scene three-dimensional visualization system

Abstract

The invention discloses a three-dimensional visualization system for an urban macroscopic scene. The three-dimensional visualization system comprises a data acquisition module, a space-time big data processing module, a space-time information service support module and a digital twinborn application design module, acquiring urban macroscopic scene data information through a data acquisition module; the data information is processed through a space-time big data processing module to obtain three-dimensional scene construction data, so that the problem that the urban three-dimensional scene data volume and the hardware resource overhead are too large is solved, and reliable data support is provided for quickly constructing the urban three-dimensional scene; a spatial data service and a spatial analysis capability are provided for constructing a city-level three-dimensional scene through a spatio-temporal information service support module, and the problem of association analysis of spatial data and business big data is solved; and through the data twin application design module, three-dimensional scene creation, special effect binding, real-time rendering, data interface definition and achievement publishing are realized, so that three-dimensional visualization of a city macroscopic scene is realized, and smart city operation management and auxiliary decision making are assisted.

Description

technical field [0001] The invention relates to the technical field of smart cities, and more particularly to a three-dimensional visualization system for urban macro scenes. Background technique [0002] At present, in recent years, with the development of science and technology and the drive of new urban development thinking, cities are constantly progressing towards digitization and intelligence. Digital cities represent the development direction of urban informatization and are an important means to promote the informatization of the entire country. , Since entering the 21st century, the digital city has developed rapidly and has become one of the strategic high-tech fields with the most development potential. [0003] The visualization of 3D scenes is one of the core contents of the current construction of "digital city", "smart city" and even "digital earth", and it has been paid more and more attention to reproduce and shape the real world in the form of 3D landscape ...

AI Technical Summary

Problems solved by technology

[0007] In view of this, the present invention provides a 3D visualization system for urban macro scenes, which solves the problem of excessive data volume and hardware resource overhead of city-level 3D scenes, and provides reliable data support for the rapid construction of city-level 3D scenes; solves the problem of spatial Analysis of the correlation between data and business big data, quickly build cool 3D scenes, realize 3D visualization of urban macro scenes, and help smart city operation management and auxiliary decision-making
