Application of UAV Oblique Photogrammetry in BIM Design of Reservoir

In the construction project of Shuidishan Reservoir in Shenshan Cooperation District,the UAV oblique photogrammetry technology is used to obtain the real 3D model of the project area,combined with manual measurement,diversified geographic information data are obtained. Based on this,BIM forward design is used to complete project formulation. The real 3D model,digital elevation model of the survey area and reservoir BIM model are used as the foundation of spatial data. The function of three-dimensional visual analysis and calculation is realized and the UAV oblique photogrammetry is successfully applied to the BIM design of the project,by serving the design and construction management of reservoir construction projects better,it provides a technical reference for the fusion application of UAV oblique photogrammetry technology and BIM Technology in reservoir construction projects.
