[Termes IGN] reconstruction 3D du bâtiIndex. décimale : 33.30 Photogrammétrie numérique Résumé : (Auteur) The thesis is based on the present state of the art of automatic photogrammetric surface reconstruction by multi-image matching in object space. This reconstruction approach can be characterised by the fact that any pixel gray value in image space is assumed to be an observation while formulating the quantities for describing the surface geometry and gray values in object space directly as unknown parameters and calculating the solution in the sense of a least squares' estimation. This very general method gives not only the possibility of a simultaneous matching of more than two images but also the broad spectrum of a complete multi-image approach: Ways for a simultaneous evaluation of data obtained from different optical sensors as well as for a simultaneous integration of multispectral and multitemporal image data are described in this thesis and illustrated by exemplary results of reconstruction.
An example given for the reconstruction of urban scenes from large-scale aerial images shows that a generalised surface representation in object space is necessary which allows vertical and even overhanging parts of the surface. Following the requirements of the photogrammetric multi-image matching, such a generalized 3-d surface model is set up and discussed in connection with the present developments in the fields of Computer Graphics and Computer Aided Geometric Design. More concretely, an irregular triangular mesh in R' is used as an explicit topological basis. This topological description is completed by transfinite, visually continuous, triangular interpolants, which allow continuity degrees from zeroth up to second order for the resulting 3-d surface model. The concept of transfinite triangular interpolation applies also to the representation of the surface gray values.
The reconstruction itself is obtained on the basis of hierarchical multigrids in object space and image pyramids in image space, respectively. Thus, the geometric surface description becomes more and more differentiated in the course of the reconstruction procedure. Formulation of the generalized 3-d reconstruction approach is made by means of the local surface normal vectors, in order to indicate the directions of the surface displacements during an iteration step of the reconstruction procedure. A permanent, explicit detection of occlusion, or here visibility in the proper sense, is integrated within the reconstruction process. Numerical topics are also treated, especially as they are of interest with respect to acceptable computation times.
The test of the reconstruction approach on the basis of the new 3-d surface modelling proves that the photogrammetric multi-image matching can profit from the generalized surface model. Exemplary reconstruction results which have been calculated using the new 3-d surface model on the one hand and the classical surface model of the form Z = f (X, Y) on the other hand are compared to each other. Scenes of open terrain show the expected comparable results, but for urban scenes a considerable increase in geometric quality of the reconstruction result could be found using the 3-d surface model.
The newly formulated 3-d surface model allows to eliminate the modelling deficits that have existed so far concerning the reconstruction of general surfaces within W. The increases in geometric quality should considerably simplify subsequent tasks like the detection and reconstruction of buildings. Furthermore, the application of the generalized photogrammetric reconstruction procedure seems to be very promising for the applicational fields of industrial and close-range photogrammetry.
Recent publications in the English language concerning various aspects of multi-image matching in object space are given by [Schlüter and Wrobel 1996] and [Wrobel and SchIüter 1997], whereas [Schlüter 1994], [Schlüter 1998] concentrate on the improvement of surface modelling in object space with respect to photogrammetric reconstruction.Numéro de notice : 46108 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Thèse étrangère Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=58468 Réservation

[Termes IGN] visualisation 3DRésumé : (Auteur) Photogrammetry has many advantages as a technique for the acquisition of three-dimensional models for virtual reality. But the traditional photogrammetric process to extract 3D geometry from multiple images is often considered too labour-intensive. In this paper a method is presented with which a polyhedral object model can be efficiently derived from measurements in a single image combined with geometric knowledge on the object. Man-made objects can often be described by a polyhedral model and usually many geometric constraints are valid. These constraints are inferred during image interpretation or may even be extracted automatically. In this paper different types of geometric constraints and their use for object reconstruction are discussed. Applying more constraints than needed for reconstruction will lead to redundancy and thereby to the need for an adjustment. The redundancy is the basis for reliability that is introduced by testing for possible measurement errors. The adjusted observations are used for object reconstruction in a separate step. Of course the model that is obtained from a single image will not be complete, for instance due to occlusion. An arbitrary number of models can be combined using similarity transformations based on the coordinates of common points. The information gathered allows for a bundle adjustment if highest accuracy is strived for. In virtual reality applications this is generally not the case, as quality is mainly determined by visual perception. A visual aspect of major importance is the photo-realistic texture mapped to the faces of the object. This texture is extracted from the same (single) image. In this paper the measurement process, the different types of constraints, their adjustment and the object model reconstruction are treated. A practical application of the proposed method is discussed in which a texture mapped model of a historic building is constructed and the repeatability of the method is assessed. The application shows the feasibility of the method and the potential of photogrammetry as an efficient tool for the production of 3D models for virtual reality applications.

[Termes IGN] réseau bayesienRésumé : (Auteur) During the last years an increasing demand for 3D data of urban scenes can be recognized. Techniques for automatic acquisition of buildings are needed to satisfy this demand in an economic way. This paper describes an approach for building extraction using digital surface models (DSM) as input data. The first task is the detection of areas within the DSM which describe buildings. The second task is the reconstruction of geometric building descriptions. In this paper we focus on new extensions of our approach. The first extension is the detection of buildings using two alternative classification schemes: a binary or a statistical classification based on Bayesian nets, both using local geometric properties. The second extension is the extraction of roof structures as a first step towards the reconstruction of polyhedral building descriptions.
