In cartographic applications, area-based matching techniques are commonly used for stereo matching of low-resolution aerial images.However, these techniques fail in matching high-resolution aerial ima...
A photogrammetric method and process to generate a portion of the lunar DEM based on the Clementine images and 93 Unified Lunar Control Network 2005( ULCN2005) control points in Leica Photogrammetric ...
Seasonal snow plays a vital role in the world's water resources. In some areas, seasonal snow melt provides water for agriculture, industry, hydro-electricity generation and urban water supply. Accura...
With the increasing availability of a diverse range of datasets from sources such as airborne and terrestrial laser scanning, InSAR, and high resolution satellite remote sensing, there are improved op...
ASTER is a high-spatial resolution, multispectral imaging system flying aboard TERRA, a satellite launched in December 1999 as part of NASA’s Earth Observing System (EOS). An ASTER scene covering 61.5...
Digital photogrammetric sensor systems that have become available during the last years provide a high potential for generating high-resolution digital elevation models (DEM) and orthoimages for large...
This paper describes the derivation of Digital Surface Models (DSMs) from 3-fold along-track stereoscopic SPOT-5 imagery in the scope of the HRS (High Resolution Stereoscopic) study, organized by the ...
This paper targets the reconstruction of 3D urban models consisting of realistic architecture models and different objects on a ground surface. When reconstructing 3D urban models it is necessary to h...
不借助控制点匹配表面来探测表面差异是一个非常困难的问题!在多时相DEM分析中具有非常广阔的应用前景.提出一个使用截尾最小二乘估计的最小高差算法(LTS-LZD)该算法在迭代过程中通过基于高差直方图的自适应阈值来区分变形区观测量.通过模拟试验对算法性能进行全面深入的试验,试验结果表明新方法具有较高的匹配精度与差异探测精度!且与变形比例基本无关.
传统摄影测量都是采用等基线摄影测量的方式,等基线的航空摄影作业对于平坦地区具有较强的适应性,但是在丘陵、山区等作业区域高程起伏较大的地区,高程的起伏会影响到相邻航空影像的航向重叠度和旁向重叠度。为了解决这一问题,详细阐述了基于曝光点调整法的变基线航线设计方法,该方法是基于1:25万的DEM实现的。实现变基线航空摄影测量的基础是实现高精度定点曝光,重点介绍了智能定点曝光算法,及如何解决利用GPS动态...
