倾斜摄影实景三维建模的孔洞修复方法

Research on automatic hole repair method based on 3D modeling of UAV tilt photography

针对倾斜摄影测量构建实景三维过程的孔洞问题,本文提出了一种可以实现孔洞自动修复的方法。首先通过边界收缩方法,编制处理程序,利用倾斜摄影测量空三处理成果,实现实景三维模型孔洞自动修复。然后利用实际的无人机倾斜摄影实景三维建模项目,采用孔洞修复试验处理,验证了孔洞自动修复方法的可行性,孔洞修复处理后模型仍具有较高精度。

Aiming at the problem of holes in the process of constructing real 3 D 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 3 D model is realized.Through the actual 3 D 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.
