Research on integrated 3D spatial modeling of urban above-ground and underground spaces
JIANG Yajing
Abstract：In response to the need for three-dimensional modeling of urban spaces,the article employs laser scanning technology to achieve integrated modeling of above-ground and underground spaces.Data were collected using the RIEGL VZ-1000 scanning system,and through steps such as control point layout,point cloud acquisition,and processing,a three-dimensional point cloud model was successfully constructed.Based on this,a three-dimensional wireframe model was created,and parametric modeling and texture mapping were implemented using the Revit platform.The results show that this method achieves a modeling accuracy of 0.016 m,significantly improving modeling efficiency and providing a reference for the construction of spatial data in smart cities.
