摘要

提出建立城市三维演示系统的一套技术流程

并针对其中的主要环节提出了可行的优化解决方案。该流程从房产数据、国土数据和规划数据等基本数据出发

利用数据分层存储的特性抽取有关建筑物、道路、水系及地形的空间数据和属性数据

并与实际采集的纹理数据结合起来

生成高分辨率城市三维演示数据。以此为基础建立城市三维演示模型。并利用VisualC ++6 0和OpenGL开发了三维演示模块

实现城市三维数据的逼真演示。在该流程的支持下

建立了扬州经济开发区三维演示系统

验证了技术的可行性和有效性

Abstract

A methodology to build 3D urban visualization system is suggested

and optimized solutions to key problems are studied.Real estate data

cadastral data

and city planning data are the fundamental data.The data of buildings

roads

water system and topography are extracted

and they are used to build urban 3D visualization models.Texture data collected with digital camera are integrated with 3D building model to generate high resolution urban visualization data.Visualization procedures are developed with Visual C++6 0 and OpenGL to visualization the 3D data.With the help of this methodology

the 3D visualization system of Yangzhou Economic Development Region is constructed

and the efficiency of the methodology is proved.
