A Monomorphic Method of Oblique Photography Model Based on 3D Scene

Abstract

In nowadays’ urban 3D modeling construction, the oblique photography technology growing up to an advancing data acquisition and modeling technology that can get a good performance in 3D scene. However, the model is composed of point cloud and Triangulated Irregular Network (TIN), so that it can’t be clicked, queried and implement to other basic functions of GIS. In this paper, we use the dividibility of triangular patches to design a tool which can cut oblique photographic model as well as pick oblique photographic data objects .Moreover it realize the Singlization of the oblique photography model according to the angle of model cutting. Experiments show that the tool can pick up the object with the user's operations. Besides, the object generation will not destroy the structure of the original data and can also completely represent the object.
