Abstract

The invention relates to a lightweight method applied to urban three-dimensional model data, and the method comprises the steps: S1, enabling an obtaining module to obtain a target image, and enabling a drawing module to draw a scene model according to the target image; s2, dividing each scene model into a plurality of layers by a division module, and storing the layers in a database module; s3, the matching module calculates the actual resolution A according to user requirements to select the corresponding scene model, and the scene model is displayed through the display module; s4, the statistical module calculates the actual display score B of each scene model so as to select whether to delete the corresponding scene model, the urban model data can be accurately updated and replaced, so that the size of the urban model data can be effectively reduced, the lightweight of the urban model data is completed, and the user experience is improved. And thus, the data lightweight efficiency is ensured.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a lightweight method applied to urban three-dimensional model data. Background technique [0002] As an important part of urban digital infrastructure, urban 3D models have a wide range of applications, such as urban planning, environmental monitoring, and spatial information analysis. When the existing technology stores the scene models, it is impossible to update and replace the scene models in the database in real time according to the actual situation of each scene model, so that the lightweight of the city model data is not complete. Contents of the invention [0003] Therefore, the present invention provides a lightweight method applied to urban three-dimensional model data to overcome the problem in the prior art that the scene models in the database cannot be updated and replaced in real time according to the actual situation of each scene model. [0004] In or...
