Abstract

High-resolution digital elevation models of urban areas can support humanitarian organisations in their work; especially the 3D reconstruction of buildings is desirable because it can be used for population estimation and damage analysis after crises and disaster events. In this paper, we test the quality of multi-date DEMs with 15 Pléiades images from Port-au-Prince, Haiti using the automatic stereo pipeline s2p. We focus on triplet combinations with images taken from different dates. This study investigates the metaparameters satellite azimuth and incident angle to understand which recording geometry yields a good result in terms of completeness and accuracy. It is assumed that the closer the multi-date constellation gets to an in-orbit triplet, the better the quality of the DEM.
城市多日期卫星立体影像数字高程模型评价
城市地区的高分辨率数字高程模型可以支持人道主义组织的工作;特别是建筑物的三维重建是可取的,因为它可以用于危机和灾害事件后的人口估计和损害分析。本文利用自动立体管道s2p对海地太子港的15幅plimades影像进行了多日期dem的质量测试。我们专注于从不同日期拍摄的图像的三重组合。本文研究了卫星方位和入射角的元参数,以了解哪种记录几何形状在完整性和准确性方面效果较好。假设多日期星座越接近在轨三联体,DEM的质量越好。
