[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] 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] traitement d'imageRésumé : (Auteur) The three-dimensional photogrammetric analysis of image sequences is a growing field of application. For the analysis of dynamic processes one important precondition has to be guaranteed: All cameras have to be synchronized, otherwise the results are affected by asynchronism. In this article a new method is presented, which can determine the asynchronism of an arbitrary number of image sequences. In contrast to already existing methods, in the new approach the asynchronism is modeled in object space and then converted into an interpolation function containing a set of unknowns for each camera. In this form the asynchronism is introduced into an extended bundle adjustment, in which the unknowns are solved simultaneously with the image orientation parameters and the object coordinates of tie points. Therefore, the approach has no restrictions with regard to the number and the set-up of the cameras in the acquisition network. Furthermore, both the temporal and spatial analysis step are carried out simultaneously. We have implemented the suggested method and have run a number of experiments in the context of vehicle impact testing. First, sequences with a frame rate of 1,000 Hz observing an object with a speed of up to 7 m/s and an asynchronism of 0.8 ms were analyzed. The accuracy of the object point determination could be improved by a factor of 10. Then, five sequences of a vehicle impact test with a speed of 15.6 m/s were investigated. Here, errors in the object coordinates of up to 30 mm could be eliminated using the new approach. Given the small tolerances in car development, this improvement in point accuracy is significant.

[Termes IGN] point de vérificationRésumé : (Auteur) In the case of sensor-independent georeferencing, accuracy of the used model is commonly assessed by misfits separately obtained from ground control points and independent check points. However, applying only this approach has some disadvantages. This paper proposes using the figure condition method to support the common approach. Applying the figure condition process, a more rigorous analysis of accuracy for the used models can be conducted, and one can decide whether the used model is proper or not. In this contribution, a case study is carried out using affine and extended affine models for high-resolution IKONOS Geo, OrbView-3 Basic, and QuickBird OrthoReady Standard images. The results obtained are subjected to the analysis of figure condition.

[Termes IGN] points homologuesRésumé : (Auteur) Direct measurement of exterior orientation parameters has been a challenge in photogrammetry for many years. Direct sensor orientation using a calibrated GPS/INS system can potentially eliminate the need for ground control points and aerial triangulation, and consequently, result in a great reduction in the cost and time of aerial photogrammetry. Previous studies have shown that, compared to conventional aerial triangulation, direct sensor orientation yields larger errors in the image and object space. It has also been shown that including a number of tie points within an integrated orientation approach can result in a reduction of errors in the image space. In this paper, the influence of the number and distribution of tie points on integrated orientation is investigated. Experiments with various numbers of tie points regularly as well as randomly distributed are presented. Results indicate that an increase in the number of tie points up to one point per model results in a considerable reduction of the errors in the image space.
