Orientation and Automated Dsm Generation from Spot-5/hrs Stereo Images
The Institute of Geodesy and Photogrammetry (IGP) at ETH Zurich participated as Co-Investor in the ISPRS-CNES initiative for the investigation on DEM generation from SPOT-5/HRS stereoscenes. A dataset consisting of an HRS stereopair, object points and reference DTMs obtained from laser data and map contours at different spacings (5x5 m, 25x25 m and 50x50 m) were provided by CNES and DLR in Ober...
متن کاملSpot 5 Hrs Location Performance Tuning and Monitoring Principles
HRS instrument on board of SPOT5 allows acquisition of stereoscopic pairs in a single pass. This instrument has been subject of specific attention even after the end of SPOT5 in flight commissioning phase. The stake was not only to fulfil HRS' location specification of 50 meters in root mean square but to obtain a location performance as best as possible and at least about 25 meters in root mea...
متن کاملDem Generation by Spot Hrs
The HRS (high resolution stereo) is an autonomous imaging system on SPOT 5. It has been designed especially for the generation of digital elevation models (DEMs). The combination of a forward and a backward view do allow a stereoscopic imaging with a height to base relation of 1.2 and just 90 seconds time interval. Some images, which are usually not accessible and used only by SPOT Image for th...
متن کاملLine-of-Sight Vector Adjustment Model for Geopositioning of SPOT-5 Stereo Images
We formulate and present a new geopositioning method for SPOT-5 High-Resolution Geometric (HRG) stereo images, named the line-of-sight (LOS) vector adjustment model. It is applicable to satellites that move along a well-defined close-to-circular elliptical orbit with a predicted orbit close to true. SPOT-5 satisfies these requirements because it has the improved capability of providing accurate...
متن کاملCombined Bundle Adjustment of Panoramic and Central Perspective Images
Based on a strict mathematical model for rotating line cameras developed at the Institute of Photogrammetry and Remote Sensing of the Dresden University of Technology, a self-calibrating bundle adjustment of panoramic image data was implemented. This model has been extended by the option to involve central perspective images of a conventional camera. A panoramic bundle adjustment is a suitable ...
