Abstract

The invention discloses a three-dimensional geographic information model rendering method and system based on a generative adversarial network, equipment and a storage medium. The method comprises a geographic information three-dimensional modeling step, a three-dimensional model generation training step, an all-terrain element matching step, a three-dimensional geographic information collaborative rendering step and a three-dimensional geographic information overall rendering step. Generation of the geographic information model is achieved through an artificial intelligence method and a generative adversarial network framework, all-terrain element matching and similar terrain theme part extraction are achieved through a sliding matching mode, non-repeated rendering of similar three-dimensional geographic information model main body parts is achieved through a mode of pre-rendering in a cache in advance, therefore, the rendering speed of the three-dimensional object is improved.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional visualization of geographic information, and in particular relates to a fast rendering method, system, device and storage medium of a three-dimensional geographic information model based on a generative confrontation network. Background technique [0002] With the research and development of remote sensing technology and sensor technology, traditional two-dimensional maps have been gradually replaced by three-dimensional maps with more information and better visualization effects. [0003] At present, whether it is a vector map or an image map, two-dimensional maps can achieve efficient rendering on the basis of existing hardware performance and optimization algorithms, meeting the needs of real-time map display and use. [0004] For 3D maps, due to the large amount of data, and the traditional rendering method needs to render all points pixel by pixel, it often consumes a huge amount of...
