Abstract: Aiming at the problem of holes in the process of constructing real 3D scene by tilt photogrammetry, this paper looks for a method that can realize the automatic repair of holes. Through the compiled boundary shrinkage method processing program and using the spatial three processing results of tilt photogrammetry, the automatic hole repair of real 3D model is realized. Through the actual 3D modeling project of UAV tilt photography, the hole repair test is adopted to verify that the automatic hole repair method is feasible, and the model still has high a ContextCapture Centeruracy after hole repair.

Key words: oblique photography, 3D real scene, 3D modeling, hole repair, boundary shrinkage method
