高分辨率立体卫星影像测绘应用潜力分析

Analysis on the Application Potential of High-resolution Stereo Satellite Image Mapping

文中是在不同系统平台上对高分辨率立体卫星影像进行立体像对处理,通过试验分析进行系统优化,形成适宜大规模生产的"高分辨率立体卫星影像一体化测图系统",在此基础上进行了DSM、DOM的自动生产实践及DLG数据采集。重点对影像定向精度进行了统计分析,最后得出了0.5 m空间分辨率WorldView-1卫星影像,能满足1∶2000比例尺地形图成图要求。

In the paper,the author deals with high-resolution three-dimensional satellite images on different system platforms and form 'high-resolution three-dimensional satellite images integrated mapping system'suitable for largescale production by experimental analysis to the system optimization and carries the DSM,the DOM automatic production practices and the DLG data collection.The author statistics and analyzes the accuracy of image orientation,and finally arrives at the 0.5 m spatial resolution WorldView-1 satellite imagery which can meet the requirements of 1:2000 scale topographic maps.
