[Termes IGN] point d'appuiRésumé : (Auteur) On s'attache dans cet article à la comparaison de deux sortes de modélisations physiques de capteurs correspondant à des images satellites issues de capteurs en peigne: dans la première modélisation on se base sur des paramètres de localisation et d'angles de rotation, et dans la seconde sur des paramètres d'orbite et d'attitude. La comparaison a porté sur la précision obtenue dans les compensations par faisceaux et sur celle avec laquelle on a pu estimer les paramètres d'orientation externe. La première a permis d'estimer la précision cartographique des deux modélisations. La seconde paraît également intéressante pour certaines applications. On a effectué des essais avec ces deux sortes de modélisations sur deux scènes provenant de la Caméra d'Observation de la Terre (EOC) de KOMPSAT-1, en utilisant des points d'appui déterminés par GPS et en mettant en œuvre différents jeux de paramètres entrés comme inconnues. En ce qui concerne la précision des compensations par faisceaux, les deux modélisations fournissent des résultats similaires tandis que pour les paramètres d'orientation celle basée sur l'orbite et l'attitude surclasse l'autre. Il semble donc préférable d'utiliser cette dernière si l'on souhaite restituer l'orbite ou l'attitude du satellite par des compensations par faisceaux.

[Termes IGN] précision du positionnementRésumé : (Auteur) During the HRS (High Resolution Stereo) Scientific Assessment Program the French space agency CNES delivered data sets from the HRS camera System with high precision ancillary data. Two test data sets from this program were evaluated: one is located in Germany, the other in Spain. The first goal was to derive orthoimages and digital surface models (DSM) from the along track stereo data by applying the rigorous model with direct georeferencing and without ground control points (GCPs). For the derivation of DSM, the stereo processing software, developed at DLR for the MOMS-2P three line stereo camera was used. As a first step, the interior and exterior orientation of the camera, delivered as ancillary data from positioning and attitude Systems were extracted. A dense image matching, using nearly all pixels as kernel centers provided the parallaxes. The quality of the stereo lie points was controlled by forward and backward matching of the two stereo partners using the local least squares matching method. Forward intersection lead to points in object space which are subsequently interpolated to a DSM in a regular grid. DEM filtering methods were also applied and evaluations carried out differentiating between accuracies in forest and other areas. Additionally, orthoimages were generated from the images of the two stereo looking directions. The orthoimage and DSM accuracy was determined by using GCPs and available reference DEMs of superior accuracy (DEM derived from laser data and/or classical airborne photogrammetry). As expected the results obtained without using GCPs showed a bias in the order of 5-20 m to the reference data for ail three coordinates. By image matching it could be shown that the two independently derived orthoimages exhibit a very constant shift behaviour. In a second step few GCPs (3-4) were used to calculate bore-sight alignment angles, introduced into the direct georeferencing process of each image independently. This method improved the absolute accuracy of the resulting orthoimages and DSM significantly.

[Termes IGN] semis de pointsRésumé : (Auteur) This paper describes the derivation and accuracy assessment of Digital Elevation Models (DEM) from 3-fold along-track stereoscopic SPOT-5 imagery. The work was conducted in the scope of the HRS (Haute Resolution Stereoscopique)-Scientifïc Assessment Program, organized by the Centre National d'Etudes Spatiales (CNES) and the International Society of Photogrammetry and Remote Sensing (ISPRS). The orientation of the SPOT-5 image scene is reconstructed by bundle adjustment using ground control points. The functional model is based on correction polynomials and permits autocalibration. At 17 independent check points a RMS-error of 2 m was achieved. DEM are produced in two different ways: The more rigorous way employs an automatic region growing image matching process generating a dense point cloud in image space, transforms it into the object space using the estimated model parameters and converts it into a regular grid DEM. In a second approach the commercial software ISAE and rational functions are applied. The comparison with a digital terrain model (DTM) of superior accuracy yields standard deviations better than 5 m in flat and moderate terrain and better than 10 m in mountainous regions. With ISAE a DEM for the entire image area (approx. 60 x 80 km) is produced with a standard deviation of approximately 8 m. All grid points were generated fully automatically, i.e. the presented standard deviations still include the effect of large differences between the produced DEM and the DTM.

[Termes IGN] traitement d'imageRésumé : (Auteur) Digital terrain models (DTMs) were extracted from SPOT-5 High Resolution Stereoscopic (HRS, 10m resolution) in-track stereo-images and High Resolution Geometric (HRG, 5m resolution) across-track stereo-images using a three-dimensional (3D) multisensor physical model developed at the Canada Centre for Remote Sensing, Natural Resources Canada, and were evaluated against precise lidar data. Firstly, the stereo HRS and HRG photogrammetric bundle block adjustments using spatiotriangulation and autocalibration were set-up with 10 ground control points and errors of about half-resolution were obtained over 190 and 95 independent checkpoints (ICPs): 6.4m, 6.8m and 5.1m in X, Y and Z axes, and 2.6m, 2.2m and 2.9m in X, Y and Z axes for HRS and HRG, respectively. The internal accuracy are, however, better because these errors include the half-pixel image plotting error and the 3m cartographic error on ICPs. Only the results with HRS were achieved with autocalibration of the lens to correct for the radial distortions due to the largest number of pixels. The DTMs were then generated using an area-based multi-scale image matching method and 3D semi-automatic editing tools, and then compared to lidar data with 0.2m accuracy in elevation. An elevation error with 68% confidence level (LE68) of 5.2m and 6.5m were achieved over the full area for HRS and HRG, respectively. Since the DTM is in fact a digital surface model where the height, or a part, of different land cover classes (trees, houses) is included, the accuracy is depending on the land cover types. Using previous 3D visual classification, different classes (forests, residential areas, bare surfaces) were generated to take into account the height of the surfaces (natural and human-made) in the accuracy evaluation. LE68 values of 3.2m to 6.7m were thus obtained depending on the land cover types. On the other hand, LE68 values of 2.4m and 2.2m were obtained over bare surfaces for HRS and HRG, respectively. These last results are more representative of the real stereo SPOT-5 potential for DTM, compliant with the highest topographic standard.

[Termes IGN] SuisseRésumé : (Auteur) High-resolution satellite images at sub-5-m footprint, such as IKONOS and SPOT5 HRG/HRS images, are becoming increasingly available to the earth observation community and their respective clients. The related cameras all use linear array CCD technology for image sensing. The processing of these kinds of images provides a challenge for algorithmic redesign and this offers the possibility of reconsidering and improving many photogrammetric processing components. This contribution presents an advanced matching approach for automatic DSM generation from high-resolution satellite images. It can provide dense, precise and reliable results. The method matches multiple (more than two) images simultaneously and it uses a coarse-to-fine hierarchical solution with an effective combination of several image matching algorithms and automatic quality control. The DSMs are generated by a combination of matching results of feature points, grid points and edges. The proposed approach has been applied to IKONOS images over a testfield in Thun, Switzerland with accurate ground control points, a 1600-m height range and variable land cover, but with sub-optimal imaging conditions (snow, long shadows). The accuracy tests are based on the comparison between the reference data from an airborne laser scanner and the automatically extracted DSMs. The RMS errors for the whole area, excluding trees and bushes, are 2-3 m, while for bare ground the accuracy is about 1 m or even better.
