| 摘 要： | 采用广义点摄影测量理论对建筑物立面框架轮廓进行重构。广义点是对当代线摄影测量以及无穷远点（灭点）理论的升华。实验结果表明,采用线面基元进行立面重构相比于经典的点云重构方法,不仅简洁、高效,还能获得清晰的三维边缘轮廓,且自动化程度较高。 |

| Abstract: | 3D model reconstructed by point cloud triangulation has some edge burrs.Taking many lines and planes information of city building into account,we suggest retrieving 3D framework model of city building facade based on generalized point photogrammetry theory,which is a sublimation for the contemporary line photogrammetry and the contemporary infinite point(vanishing point) theory.Firstly,initial values of image orientation element can be got by vanishing points.Then,straight-lines of object space are achieved... |
