[Termes IGN] point d'appuiRésumé : (Auteur) Geometric sensor models are used in image processing to model the relationship between object space and image space and to transform image data to conform to a map projection. An Rational Polynomial Coefficient (RCP) is a generic sensor model that can be used to transform images from a variety of different high resolution satellite and airborne remote sensing systems. To date, numerous researchers have published papers about RPC refinement, aimed at improving the accuracy of the results. So far, the Bias Compensation method is the one that is the most accepted and widely used, but this method has rigorous conditions that limit its use; namely, it can only be used to improve the RPC of images obtained from cameras with a narrow field of view and small attitude errors, such as those used on Ikonos or QuickBird satellites. In many cases, these rigorous conditions may not be satisfied (e.g., cameras with a wide field of view and some satellites with large ephemeris and attitude errors). Therefore, a more robust method that can be used to refine the RPC under a wider range of conditions is desirable. In this paper, a generic method for RPC refinement is proposed. The method first restores the sensor’s pseudo position and attitude, then adjusts these parameters using ground control points. Finally a new RPC is generated based on the sensor’s adjusted position and attitude. We commence our paper with a review of the previous ten years of research directed toward RPC refinement, and compare the characteristics of different refinement methods that have been proposed to date. We then present a methodology for a proposed generic method for RPC refinement and describe the results of two sets of experiments that compare the proposed Generic method with the Bias Compensation method. The results confirm that the Bias Compensation method works well only when the aforementioned rigorous conditions are met. The accuracy of the RPC refined by the Bias Compensation method decreased rapidly with the sensor’s position error and attitude error. In contrast to this, the Generic method proposed in this paper was found to yield highly accurate results under a variety of different sensor positions and attitudes.

[Termes IGN] point de fuiteRésumé : (Auteur) A new automated approach for vanishing point detection in images of urbanscenes is described. This method is based on the theorem of Thales. The maincontribution of this paper is the automatic and simultaneous detection of allvanishing points of the image, achieved by converting this problem into the detectionof circles in a complex cloud of points, in which each point corresponds to a segmentand is associated with an uncertainty. This extraction of circles uses a RANSACmethod, modified to improve its speed by using accumulation techniques (Houghtransform or otherwise). This robust estimation is then refined by least squares errorpropagation using the individual variances of each segment. The algorithm is robust,its accuracy is optimised and it is entirely automatic. Its successful operation hasbeen tested on a large number of images of varied urban scenes.

[Termes IGN] qualité géométrique (image)Résumé : (Auteur) Accuracy and reliability are two popular indicators for assessment of the quality of aerial triangulation. This paper explores these quality indicators in relation to GPS-supported bundle block adjustment based on aerial digital frame imagery with GPS navigation data. A set of aerial digital frame imagery, taken over hilly terrain using an SWDC-4 area-array digital camera made in China, was selected and used. These empirical images have superior resolution with a pixel size of 9 um, with a ground sample distance of 10 cm and larger than traditional overlaps (80% longitudinal and 63% lateral). GPS-supported bundle block adjustment was carried out with the WuCAPS high-precision combined bundle block adjustment software package developed by the author. The achieved a posteriori standard deviation (rms errors of observation residuals) of the image coordinates is +3·7 um. The empirical accuracy of the photogrammetric point coordinates reaches +7·1 cm for planimetry and +4·8 cm for elevation on the ground, and the average redundancies (average components of the redundancy for one kind of observation) of the image coordinates and the camera station coordinates determined via GPS are more than 0·74 and 0·69, respectively. These results have shown that GPS-supported aerial triangulation with aerial digital frame imagery provides higher precision and reliability; the practical height accuracy is close to its theoretical possibility; also, it avoids the use of the cross strips and lines of ground height control points on each side of the adjusted block. This not only changes the present situation, in which height accuracy is always lower than the planimetric accuracy in aerial triangulation of aerial film images, but also opens up a new prospect in which the orientation points for models for stereoplotting need not be determined by full field surveying for topographic mapping of reasonably flat terrain at medium and large scales. Therefore, this paper provides an operational basis for a broad range of applications for aerial digital imagery in national basic surveying and mapping, and the rapid production and updating of geographic information in general.

[Termes IGN] séquence d'imagesRésumé : (Auteur) This paper deals with a novel imaging arrangement for special modeling purpose. The method introduced here will take care of the geometrical consistence of photography. It is based on image ray bundles and is meant for conditions where imaging is accomplished inside the object space (e.g. in case of interior model reconstruction). Imaging is designed to be contrained in terms of camera position and orientation and to consist of two image sequences. The image orientation will be resolved by use of LSQ-estimation in heavily overdetermined conditions. The benefits of overdetermination are discussed and the accuracy assessment in a real experiment is published. The accuracy assessment is accomplished with help of exterior reference and stochastic error programmation.
