Research on the construction method of demand-oriented Hybrid LOD modeling for 3D building model
In view of the problems of large data volume,redundant details,and heavy platform load in current 3D digital city simulation applications,this article proposes a demand-driven 3D building hybrid detail level model construction method from the perspective of application requirements.The method expands and optimizes on the basis of the LOD regulations of the OGC international standard CityGML,and believes that a better LOD design idea should be application-oriented and serve the application.Based on the importance of model parts to specific applications,a"focus+context"strategy is adopted for lightweight reconstruction of 3D building model,aiming to ensure that the application requirements are met while reducing the redundancy and data volume of model details.This method provides new ideas and directions for urban 3D model modeling and application,and has important theoretical and practical value for promoting the development of 3D digital cities and facilitating the realization of smart cities and digital twin cities.
