Abstract
In order to solve the problem that the surface model of multi-view-stereo reconstruction is distorted and the plane of the building is uneven, which causes the error of texture mapping and garland, a method of 3D reconstruction of urban buildings with linear constraint is proposed.The method uses a series of pictures obtained by the UAV as input.Firstly, straight line segment and edge are extracted by line segment detector and super-pixel.After the polygon simplified, 2D single triangle 2D mesh is obtained by 2D constrained Delaunay triangulation.Then, according to the dense point cloud, the 3D position of 2D triangular mesh vertex is back-calculated, and the single view 3D mesh model is obtained.Finally, the multi-view merges to obtain the complete scene 3D model.The experimental results show that the proposed algorithm has good performance, stability and expansibility, and has high accuracy and efficiency.关键词
