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 by matched lines. Next, bundle block adjustment based on generalized point (lin...
