Model fusion method and related device

Abstract

The embodiment of the application discloses a model fusion method and a related device, which are applied to electronic equipment. The method comprise the steps: obtaining a target building currentlyselected by a user and a browsing view angle of the target building; determining a to-be-displayed model data combination of a building information model (BIM) and a to-be-displayed model unit of a geographic information system (GIS) model according to the browsing view angle of the target building; loading first model data corresponding to the to-be-displayed model data combination and second model data corresponding to the to-be-displayed model unit, the first model data being part of model data of the target building BIM; and fusing and displaying the BIM and GIS models corresponding to thetarget building. According to the embodiment of the application, the BIM and GIS models of the target building can be better fused and displayed according to the requirements of different applicationscenes.

Description

technical field [0001] The present application relates to the technical field of architectural models, in particular to a model fusion method and related devices. Background technique [0002] In the prior art, the real scene 3D model in the field of geographic information system (Geographic Information System, GIS) focuses on the macroscopic expression of buildings and surface phenomena, and has the characteristics of high precision, high fidelity, and measurability, while the building information modeling (Building Information Modeling) Modeling (BIM) focuses on the expression of 3D model details, with detailed parameters and business attributes. At present, there are still some deficiencies in the deep integration of GIS and BIM, because the data collection methods and model generation methods of GIS real-scene 3D models and BIM are different. It is difficult to achieve in-depth integration applications, and the BIM data is huge. If the BIM has not been lightweighted, the...

[0002]In the prior art, the real scene 3D model in the field of geographic information system (Geographic Information System, GIS) focuses on the macro expression of buildings and surface phenomena, with high precision, high Realistic, measurable, etc., while Building Information Modeling (Building Information Modeling, BIM) focuses on the expression of 3D model details, with detailed parameters and business attributes. At present, there are still some shortcomings in the deep integration of GIS and BIM, because GIS The real-world 3D model and BIM have different data acquisition methods and model generation methods, so it is difficult to achieve in-depth fusion and application, and BIM data is huge. If BIM is not light-weighted, it will have poor performance when loaded into GIS for 3D display. poor fluency
