Research on 3D Assisted Planning and Approval of Urban Infrastructure Projects Based on UAV Oblique Photogrammetry

The approval of urban infrastructure project planning and design schemes are an important part of urban planning and a planned blueprint formulated for urban development. Quickly realizing the three-dimensional planning and approval of urban infrastructure projects plays an important role in the reasonable layout and spatial arrangement of cities. Based on UAV oblique photogrammetry, this paper fuses the real-scene three-dimensional model with the planned MAX model for scene integration, and conducts three-dimensional effect simulation from various perspectives, reflecting the efficiency, intuitiveness, and scientific nature of urban three-dimensional assisted planning and approval. The feasibility of this method is verified by the actual case of three-dimensional planning and approval in Laoshan District.
