The paper describes the comprehensive testing of the digital photogrammetric modules forming parts of the image processing systems available from a number of remote sensing system suppliers - PCI, ERD...
基于干涉合成孔径雷达(Interferometric SAR, InSAR)技术生成高精度数字高程模型(Digital Elevation Model, DEM)，需要进行干涉定标。繁重的地面控制点(Ground Control Points, GCPs)布放不利于InSAR大区域地形测绘的自动化。该文介绍一种稀疏GCPs下，基于自动提取的连接点(Tie Points, TPs)，利用最小二乘平差...
