Paper Abstract

Interest in 3D city Modeling and quickly updating have significantly raised in the past years. In this paper, an economically viable solution for city modeling based on strict digital photogrammetric theory is proposed. Two oblique image sequences for buildings' walls and one vertical image sequence for building's roof, acquired by digital video camera on helicopter, coarse 2D vector data of buildings and LIDAR data are used as sources of information. Camera parameters of each image are acquired by automatic aerial triangulation technique for high overlapping image sequence. By matching every space edge of the building to its image line, the building is accurately reconstructed. The visualization of 3D city model is realized based on the reconstructed buildings with fine textures superimposed on DSM and orthoimage.
