基于无人机倾斜摄影的建筑物三维建模尝试

近年来随着科学技术水平的不断提高，航天航空技术、网络通信技术、计算机技术和信息技术呈现飞速发展，遥感数据获取能力得到了有效提升，形成了以多源（多平台、多角度、多传感器）、高分辨率（光谱、时间、空间、辐射）为特点的高效、多样、快速的空天地一体化数据获取手段。本文以拓普康猎鹰8号八旋翼无人机平台为例，通过分析该平台获取的低空摄影测量数据，利用Smart3D软件对建筑物进行建模，为智慧城市的三维系统建设提供有力的技术保障。

An attempt of building 3D modeling based on UAV tilt photography

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.
