Abstract：The paper elaborates on the 3D modeling technology of drone oblique photography,and takes the Luo Family Ancestral Hall in Linhe Ancient City as the research object.Based on the terrain characteristics of the research area,image control points are set up,and the DJI Elf 4 RTK drone is used to obtain images of the Luo Family Ancestral Hall and construct a 3D model.Set up checkpoints,compare and analyze the coordinates of the 3D model checkpoints with the measured checkpoint coordinates,and verify that the accuracy meets the relevant specifications through comparison.
