[Termes IGN] superposition d'imagesRésumé : (Auteur) Accurate image registration is essential for the successful creation and interpretation of multi-image spatial information products. However, the enormous increase in the volume of remotely sensed data that is being acquired by an ever growing number of Earth Observation satellites means that automation now plays a more vital role than ever before in the registration procedure. This paper introduces an improved model for automatic feature-based image registration, and presents a robust system for automatically registering SAR and SPOT imagery. The model incorporates multiple feature extraction and feature matching algorithms which operate together to identify common features in the multi-sensor images, from which accurate tie points can be derived. Application of the proposed automatic registration model to both small and large images showed that in each case a large number of accurate tie points could be identified fully automatically across the images.

[Termes IGN] transformation de HoughRésumé : (Auteur) The automation of relative orientation (RO) has been the major focus of the photogrammetric research community in the last decade. Despite the reported progress, there is no reliable (robust) approach that can perform automatic relative orientation (ARO) using large-scale imagery over urban areas. A reliable and general method for solving matching problems in various photogrammetric activities has been developed at The Ohio State University. This approach has been used to solve single photo resection using free-form linear features, surface matching and relative orientation. The approach estimates the parameters of a mathematical model relating the entities of two data sets when the correspondence of the involved entities is unknown. When applied to relative orientation, the co planarity model is used to relate extracted edge pixels and/or feature points from a stereo-pair. In its execution, the relative orientation parameters are solved sequentially, using the co planarity model to evaluate all possible pairings of the input primitives and choosing the most probable solution. As a result of this technique, the matched entities that correspond to the parameter solution are implicitly determined. Experiments using real data conclude that this is a robust method for relative orientation for both urban and rural scenes.

[Termes IGN] photogrammétrie métrologiqueRésumé : (Auteur) Area-based least squares matching has existed since the 1980s, and its development may therefore be regarded by some photogrammetrists as complete. However, this is a relatively short time in a rapidly changing discipline, and the method does have scope for further refinement. This paper aims to enhance the fidelity of the fundamental mathematical model, which relates pixel positions in area-based matching. If successful, its benefit is seen to lie within close-range photogrammetry, in which object undulations, convergent camera directions and large image scales can introduce significant levels of perspective distortion. It is hypothesised that a model, which takes into account the surface shape within the match window, would provide a pixel position relationship which is applicable across larger windows than those which are applicable with the conventional matching model, based on an affine transformation. The use of larger windows for the image matching increases the redundancy. Revised co-ordinate transformations, based on mathematical surface models across the windows, are proposed in this paper. When tested on the measurement of real objects, even simple surface models are found to increase the complexity of the matching mathematics, but when compared with the traditional affine transformation solution using three test objects, precision improved noticeably. Generally, accuracy also improved, but the improvements were not as distinct as they were for precision. Quicker convergence with fewer iterations was usually obtained, and this is seen as particularly indicative of a more faithful model. Yet more rigorous surface modelling may be worth developing, but the means of choosing the most appropriate models for different objects also remains a question deserving to be pursued.

It discusses important developments in the Earth observation field, and includes substantial new material on application areas, the Envisat mission and new areas of technology such as the internet. The book opens with the basic techniques of satellite geocoding (including the use of GPS and mosaic production) before describing a wide range of algorithms for extraction of information from optical and radar satellite images. It then addresses the derivation of topographic information from space (including the recent shuttle Radar Topography Mission (SRTM) followed by an explanation of the added-value obtained through the integrated use of geocoded satellite data in a Geographic Information System (GIS). Practical commercial and scientific applications, such as agriculture, civil engineering, and the oceanographic, atmospheric and cryospheric worlds, are then described in detail. The book reviews recent developments in environmental monitoring and global security such as hazard and disaster monitoring, population dynamics and space missions dedicated to environmental monitoring (such as the Earth Observing System and the European Envisat Mission). Finally, the author draws together all the threads under the generic term of geomatics - addressing cuting-edge developments such as Very High Resolution Imagery (VHR) and the role that satellite data may play in the development of Location Bases Services for the third-generation telecom market.
