Problems solved by technology

[0005] In order to overcome the geometric modeling and visual representation of objects in related technologies at least to a certain extent, as well as the long modeling time due to the traditional manual construction of LOD models in the massive modeling of 3D large scenes, the models are loaded all at once In the 3D scene, the initialization time is also long, and the problem of fast dynamic display, browsing and scheduling cannot be realized. This application provides a 3D large scene modeling data processing method and device

Embodiment Construction

[0059] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0060] figure 1 It is a flowchart of a three-dimensional large scene modeling data processing method provided by an embodiment of the present application.

[0061] like figure 1 As shown, the method of this embodiment is used for the scheduling of massive data in three-dimensional large scenes, including:

[0062]S11: Obtain solid model data from 3D large scene modeling data;

[0063] S12: storing the entity model data into the monomer database;

[0064] S13: Compile the monomer database, and convert the model description data in the monomer database into triangulation model data;

[0065] S14: Generate a tile library for creating a tile map pyramid model based on the compiled monomer database;

[0066] S15: Schedule the corresponding tile data in the tile library in real time, load it into the scene for display.

[0067] Applying the above meth...

Abstract

The invention relates to a three-dimensional large-scene modeling data processing method and device and computer equipment. The three-dimensional large-scene modeling data processing method comprisesthe steps of obtaining entity model data from three-dimensional large-scene modeling data; storing the entity model data into a single database; compiling the single database, and converting the modeldescription data in the single database into triangulation network model data; generating a tile library for creating a tile map pyramid model based on the compiled single database; and scheduling corresponding tile data in the tile library in real time, and loading the tile data in a scene for display. According to the method, the workload of traditional manual modeling is saved, the modeling period is shortened, the model accuracy is high, the model is finer, and the user experience effect is improved; moreover, quick loading display can be realized, the scene lagging phenomenon is reduced,and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of geographic information systems, in particular to a data processing method and device for three-dimensional large-scale scene modeling. Background technique [0002] GIS (Geographic Information System), based on spatial information, comprehensively uses remote sensing, virtual reality, global positioning system, computer network and other technologies to truly reflect the real appearance of a city in the computer. Terrain, buildings, roads, plants, sketches, rivers, vector data, underground pipelines and a large number of human and social attributes related to it. [0003] 3D visualization is an important function of geographic information system GIS. In the field of geographic information systems, traditional data visualization methods are mostly two-dimensional display, such as Baidu map, Google map, etc. [0004] In the related art, a three-dimensional visualization technology is used to dis...
