Abstract
The splitting property of triangle patches are used to solve the problem of achieving the separate 3D building model to be single based on oblique photogrammetry image. Firstly, this paper draws a cutting polygon to determine the model boundary. Then bounding box is used to make the intersection detection to obtain the triangle patches which need to be cut. And the intersection points of triangles are found which may intersect with cutting polygon. Each of intersecting cases is detailed introduced and analyzed. All these intersection should be cut according to their actual conditions respec-tively. The cut triangular patches should be reconstructed. Through reconstructing the texture and levels of detail can achieve the separate 3D building model to be single. The experimental results show that this method can effectively achieve 3D model to be single.关键词
