Abstract: In recent years, with the constantly improve of the level of science and technology, aerospace technology, network communication technology, computer technology and information technology rapid develop, the getting ability of remote sensing data has been effectively promoted, formed by the source (multiple platforms, multiple perspectives, multiple sensors), high resolution (spectrum, time, space, radiation) as the characteristics of high efficiency, diversity, rapid empty world integration of the data acquisition method. Taking Topcon falcon 8 eight-rotor UAV platform as an example, this paper analyzes the low-altitude photogrammetry data obtained by the platform, and uses Smart3D software to model buildings, so as to provide strong technical support for the three-dimensional system construction of smart city.

Key words: multi-rotor UAV platform, photogrammetry at low altitude, Smart3D software
