Construction of component-level urban 3D model based on oblique photography Mesh model and laser point cloud
To construct a component-level urban three-dimensional(3D) real scene model,this paper explored the modeling methods of buildings,components,and urban scenes based on the techniques of oblique Mesh model modeling and laser point cloud modeling. Finally,these modeling methods were integrated to construct a component-level urban 3D real scene model, and are applied to the national new fundamental surveying and mapping Beijing pilot-sub center canal two bank business district 3D real scene modeling project. All this contributes to the construction of new fundamental surveying and mapping in Beijing.
