Embodiment

[0027] like figure 1 As shown, the data classification request rendering method based on the CIM platform in this embodiment adopts the fusion storage data format to perform hierarchical fusion storage and rendering on the input city information model (CIM) platform items and multi-source data. In the process of hierarchical fusion storage, multi-source data is classified and expanded, and LOD14-LOD21 (Levels of Detail, multi-level of detail) data is classified, and data or models stored under different levels are defined; finally, according to The data characteristics of different levels adopt different data slicing methods, so that multi-source data can be efficiently hierarchically fused and stored; for example, three-dimensional data and two-dimensional data are stored separately. When two-dimensional data is stored in the form of tiles at each LOD level, the traditional quadtree cut graph (also called slice) is used. The types of cut graphs are divided into compact type a...

Abstract

The invention belongs to the technical field of computer application, and discloses a data grading request rendering method and system based on a CIM platform, and the method comprises the following steps: carrying out the grading expansion of two-dimensional and three-dimensional data models based on the related international standard of the CIM platform, and dividing the highest levels of data of the LOD level according to the fineness; according to the expanded two-dimensional and three-dimensional data model grading, defining data or models needing to be displayed in each grading section; determining storage modes of two-dimensional and three-dimensional data on each LOD level according to an optimal mode required by data display; and according to the requirement of a rendering scene, requesting data of a corresponding structure, and performing rendering display by responding to a data loading request in a grading manner. According to the method and system, data storage is carried out on the hybrid model under the corresponding level through level-to-level management of data of different dimensions, fused data is read from different data storage under different scales, and an efficient storage format is provided for multi-source data rendering.

Description

technical field [0001] The invention belongs to the technical field of computer application, and specifically relates to a data classification request rendering method and system based on a CIM platform. Background technique [0002] With the development of smart cities, the Internet of Things, and 3D technology, two-dimensional data can no longer meet the needs of smart city applications. As the basic operating system of smart cities, the CIM platform has comprehensively promoted IoT data, oblique photography, single model, With the access of BIM models, the CIM platform will continue to integrate other multi-source data to realize refined simulation of cities. [0003] However, problems such as high data calculation and cost, unreasonable data slicing, unreasonable index structure, and slow data access speed are also exposed during the fusion and refinement of multi-source data, seriously affecting the user experience of the CIM platform.
