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World View-3、Geo Eye-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。Aiming at the difficulty of refined 3 D modeling data acquisition and product production technology in typical overseas regions,this paper designs a high-resolution optical satellite image refined 3 D modeling method.In this method,the central area of Dubai is selected as the experimental area.High-resolution satellite image data such as World View-3 and Geo Eye-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 3 D model production of the main buildings in the area,and forms a high-resolution satellite image 3 D modeling prototype system,which meets the needs of the accuracy and fineness requirements of quickly produce 3 D digital models production in global geographic information resource construction projects.
