[Termes IGN] précision géométrique (imagerie)Résumé : (Auteur) This research investigated the accuracy in three-dimensional (3D) geopositioning achieved by integrating Ikonos and QuickBird images using the vendor-provided rational polynomial coefficients (RPCs). One pair of stereo Ikonos images and one pair of stereo QuickBird images were collected for the same region of Tampa Bay, Florida, and used in this study. Results of 3D geopositioning from different combinations of Ikonos and QuickBird stereo images were generated by using an improved rational function model (RFM). The relationship between the satellite-borne pointing geometry and the attainable ground accuracy is examined. This research demonstrates that the integration of Ikonos and QuickBird images is feasible and can improve the 3D geopositioning accuracy using a proper combination of images.

[Termes IGN] point d'appuiRésumé : (Auteur) Elevations for digital surface model (DSM) generation were extracted from different stereo high-resolution (HR) images (QuickBird and Ikonos) using 3D physical and empirical geometric models. The 3D physical model is Toutin's model (TM) developed at the Canada Centre for Remote Sensing, and the empirical model is the rational function model (RFM). First, Vendor-supplied RFMs refined with polynomial functions and TM were compared for the sensor orientations with least-squares adjustments with different number of ground control points (GCPs). TM and RFMs gave similar results with Ikonos as soon as RFM was refined with a shift computed from at least one GCP. On the other hand, TM gave better results than RFMs with QuickBird regardless of the number of GCPs. Due to relief dependency, QuickBird RFM needed to be refined at least with linear functions computed from at least 6-10 GCPs. Some large errors were, however, noted on forward image RFM in column. The stereo-extracted elevations of DSMs were then compared to 0.2-m accurate Lidar elevation data. Because DSM stereo-extracted elevations included the height of land covers (trees, houses), elevation linear errors with 68 percent confidence level (LE68) were computed for the entire area and three land-cover classes (forested, urban/residential, bare surface). TM and RFMs with Ikonos, regardless of the method and GCP number, achieved comparable results for all classes while TM achieved overall better results than RFMs with QuickBird. All results demonstrated the necessity of refining Ikonos RFM with a tri-directional shift and at least one GCP but QuickBird RFM with 1st order linear functions and 6-10 GCPs.

[Termes IGN] transformation linéaire directeRésumé : (Auteur) Very high resolution optical space images are coming more and more into competition to classical aerial images making them more important for mapping projects. The orientation process of the dominating CCD-line scanner images taken from space is quite different from the orientation of perspective photos. Different image products like nearly original images and images projected to a plane with constant height are available, this requires corresponding orientation solutions. All optical satellites are equipped with direct sensor orientation based on a positioning system, gyros and star sensors, so they can estimate the orientation parameters. For IKONOS, QuickBird and OrbView-3, this can be made without control points with a standard deviation of the ground coordinates in the range of 10 m and better. The orientation information is available as view direction from the scene centre or start of scene or as ephemeris and as rational polynomial coefficients (RPCs). This allows the determination of the scene orientation by geometric reconstruction or bias corrected RPCs using control points. In addition approximations like 3D-affine transformation, direct linear transformation and terrain related RPCs are in use. The accuracy of the methods is compared in relation to the number and distribution of the control points and the limitations of the approximations are investigated. The approximations of the orientations by 3D affine transformation and direct linear transformation can only handle images projected to a plane with constant height like IKONOS and QuickBird or Standard. For original images they are not leading to acceptable accuracy. In any case they require more and three-dimensional well distributed control points.

[Termes IGN] modèle stéréoscopiqueRésumé : (Auteur) This research study addressed and compared 3D physical and empirical models for stereo-processing and the generation of digital surface models (DSMs) from different stereo high-resolution (HR) sensors (Ikonos and QuickBird). The 3D physical model is Toutin's Model (TM) developed at the Canada Centre for Remote Sensing, and the empirical model is the rational function model (RFM). The study also evaluated the conditions of experimentation to appropriately use these 3D models. The first results on stereo-bundle adjustments demonstrated that TM and vendor-supplied RFMs gave similar results with Ikonos as soon as RFM was refined with a shift computed from one GCP. On the other hand, TM gave better results than vendor-supplied RFMs with QuickBird regardless of the polynomial order and the number of GCPs. Due to its relief dependency, QuickBird RFM needed to be refined at least with linear functions computed from at least 6 to 10 GCPs. Some large errors were, however, noted on forward image RFM in column. The DSMs were then generated using an intensity matching approach and compared to 0.2 m accurate lidar elevation data. Because DSMs included the height of land-cover (trees, houses), elevation linear errors with 90 percent confidence level (LE90) were computed and compared for the entire area and three land-cover classes (forests, urban/ residential, bare surfaces). TM and vendor-supplied RFMs with Ikonos, regardless of the method and GCP number, achieved comparable results for all classes, while TM achieved overall better results than vendor-supplied RFMs with QuickBird. All results demonstrated the necessity of refining Ikonos RFM with a shift and one GCP only and QuickBird RFM with lst-order linear functions and 6 to 10 GCPs due to its relief dependency.

[Termes IGN] point d'appuiRésumé : (Auteur) The adoption of rational functions as a preferred sensor orientation model for narrow field of view line scanner imagery accompanied the introduction of commercial high-resolution satellite imagery (HRSI) at the turn of the millennium. This paper reviews the developments in ground point determination from HRSI via the model of terrain independent rational polynomial coefficients (RPCs). A brief mathematical background to rational functions is first presented, along with a review of the models for generating RPCs from a rigorous sensor orientation, and for geopositioning via either forward intersection or monoplotting. The concept of RPC block adjustment with compensation for exterior orientation biases is then discussed, as is the means to enhance the original RPCs through a bias correction procedure. The potential for RPC block adjustment to yield sub-pixel geopositioning accuracy from HRSI is illustrated using results from experimental testing with two Quickbird stereo image pairs and three multi-image IKONOS blocks. Finally, error propagation issues in RPC block adjustment of HRSI are considered.
