摘要
基于不同系统平台对高分辨率立体卫星影像进行立体像对处理,通过实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",并在此基础上进行了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,能满足平原和丘陵地区1∶2000比例尺地形图的成图要求。
In this article,after processing the high resolution stereo satellite images on different system platform,and making system optimization through the test analysis,a suitable large-scale production system of＂high-resolution stereo satellite images integrated mapping system＂is formed.On this basis,DSM,DOM automatic production and DLG data collection are conducted.The author focuses on the statistical analysis of the images’orientation accuracy,and finally come to a conclusion： the 0.5 m spatial resolution of WorldView-1 satellite images can meet the topographic map of 1∶2000 scale in flat hill area.
