【摘要】 探讨了一套以无人驾驶飞行器遥感影像为基础,在现有二维GIS数据支持下的三维城市建模技术方案。根据虚拟现实技术三维建模的基本原理,结合已完成并通过验收的“数字威海”三维地理空间基础框架,详细论述了数字城市中纹理建模和几何建模的关键技术及建模方法。更多还原

【Abstract】 This paper presents a technical scheme of three-dimensional city modeling based on the image of UAV (Unmanned Air Vehicle) and the existing data of two-dimensional GIS. In terms of the basic theory of virtual reality in three-dimensional city modeling , the key technology and method of texture modeling and geometry modeling in the construction of digital city are discssed in de-tailly combining with the project of digital-Weihai.更多还原
