摘要: 针对境外典型区域精细化三维建模数据获取与产品制作技术难点,本文设计归纳出一种高分辨率光学卫星影像精细化三维建模方法。选取迪拜市中心城区为试验区域,以WorldView-3、GeoEye-1等主流高分卫星影像为主要数据源,以互联网众源影像为辅助数据源,利用卫星影像精准定向精化的RPC参数及生成的精准几何信息(DSM/DOM),完成区域内主要建筑物的三维模型生产制作,并形成高分辨率卫星影像三维建模原型系统,满足全球地理信息资源建设与维护更新工程,快速制作符合精度和精细度要求的三维数字模型的需要。

Abstract: Aiming at the difficulty of refined 3D modeling data acquisition and product production technology in typical overseas regions, this paper designs a high-resolution optical satellite image refined 3D modeling method. In this method, the central area of Dubai is selected as the experimental area. High-resolution satellite image data such as WorldView-3 and GeoEye-1 are selected as the main data source, and multi-source image downloading from internet is used as the auxiliary data.The method uses accurate orientated refined RPC parametersand the precise geometric information (DEM/DOM) to complete 3D model production of the main buildings in the area, and forms a high-resolution satellite image 3D modeling prototype system, which meets the needs of the accuracy and fineness requirements of quickly produce 3D digital models production in global geographic information resource construction projects.

Key words: 3D modeling, monomerization, high-resolution satellite image, multi-source image online, global geographic information resource construction
