摘要
以资源三号卫星三线阵影像为数据源,基于无控制区域网平差、三线阵影像的核线影像重构、多基线匹配、密集匹配、基于几何约束的半全局优化匹配策略、用SRTM 30m DEM填补DSM空洞等关键技术,实现全国DSM的快速自动生产与质量控制,并进行了试验验证。
In this paper, the automatic generation and quality control of ZY-3 DSM have been realized and verified by ex- periments on the basis of block adjustment technology, GCPs of large area satellite imagery, multi-baseline matching technique, dense matching technique, optimal matching strategy of all half bureau which is based on geometric con- straints and SRTM 30 m DEM filling. And experiment was carried out.
