摘要
三维数据的有效管理是丰富集成应用的基础。在大量三维模型生产的基础上,如何实现既具有几何又具有纹理与属性信息的三维模型原始数据的有效管理,同时与应用系统进行无缝集成对接是当前三维数字城市的一个难点。本文通过对三维数字城市的数据体系与模型的研究,提出了对于各类三维模型的一体化集成与管理方法。以常州为例,通过数据的管理与三维应用系统的集成,实现了三维数据的高校管理与应用。
Effective management of three-dimensional data is the basis of rich integrated application.On the basis of a large number of three-dimensional model production,how to achieve both a three-dimensional geometric model of effective management but also has texture and properties of the original data ,and seamless integration with the application system is a difficulty of current three-dimensional digital city.In this paper,through the study of three-dimensional dig-ital model of the city＇s data system to proposed a three-dimensional model of integration for all types of integration and management methods.In case of Changzhou,through systems integration of data management and 3D applications,to a-chieve a three-dimensional data efficient management and applications.
