Abstract: 3D modeling based on oblique image of unmanned aircraft is the first choice for 3D modeling of the city because it is fast and low cost. Multiple problems, such as data redundancy, model deformation and image deletion, often affect the modeling effect in the 3D modeling based on oblique image of unmanned aircraft. This paper puts forward a series of model refinement treatment technology for 3D modeling based on oblique image of unmanned aircraft. These techniques make the 3D model more vivid and realistic.

Key words: oblique image of unmanned aircraft, three-dimensional modeling, model deformation, image missing, model refinement
