基于倾斜摄影测量技术的三维数字城市建模

Three Dimensions Modeling of Digital City Based on Oblique Photogrammetry Method

在丹阳市数字城市三维建模生产中,利用倾斜摄影测量技术及相关快速建模的方法实施数字城市三维建模生产,本文总结了一套快捷高效的适合于实际生产操作的技术方案,该技术方案能显著提高测绘生产效率。贴近作业生产,切合实际,对于数字城市三维建模和测绘生产具有较好的参考借鉴作用。特别是对于大范围区域的三维建模,能有效地实现速度和逼真度的兼顾,显示其优越性。

In the 3D modeling production of I）anyang digital city, Oblique photogrammetry method and fast 3D modeling tech-nology are used, this paper summarized a technical scheme which is suitable for the actual production operation. It is proved that the method of modeling has the high speed and efficiency, having a good reference in 3D modeling of digital city and map-ping production. It can realize great balance of demand of speed and fidelity and show great advantages especially for large areas.
