In this thesis, the reconstruction of 3D building models from aerial images is addressed. The approach presented in this thesis integrates the aerial images analysis with information from a GIS database and domain knowledge.
The problem of automatic 3D building reconstruction has been a central research topic in computer vision and image understanding communities as well as in digital photogrammetry for many years. A variety of approaches has been suggested for the reconstruction of buildings from aerial images. Despite considerable research effort, there is no complete system that can reliably perform autonomous 3D building reconstruction in a wide variety of scene domains. This is particularly true in complex urban areas containing buildings with different shapes and roof types as well as in complicated underlying terrain. Of course, some progress has been made, but there is room for improvement. This improvement can be achieved by fusing multiple data sources and some a priori information.
In this project, largescale 2D GIS databases were used as additional information source. Combination of image data and map data turned out to improve the reliability of the reconstruction. Generic knowledge about the shape of the buildings is also incorporated in the system. Since most buildings can be described as an aggregation of simple building types, the knowledge about the problem domain can be represented in a building library containing simple building models. Therefore, a building library was defined containing the most common building primitives, such as flat roof, and different types of gable roofs.
The building reconstruction process was formulated as a multilevel hypothesis generation and verification scheme and it was implemented as a search tree. A method that can localize the buildings in images using map information has been developed. Also, a method for generating building hypotheses corresponding to the primitives defined in the building library has been developed. This implies stereo matching of image features (corners, lines) which correspond to map primitives and fitting of the building hypotheses to images.
A further contribution is the definition of a metric for evaluating the generated building hypotheses in order to select the one which best describes the image. The metric is based on the formulation of the mutual information between the building model and the images. Methods for the estimation of the mutual information from training samples were analyzed. This metric has been rigorously derived from information theory and does not require a priori information about the surface properties of the object and is robust with respect to variations of illumination. Also, no assumption about the shape of the objects are made. As result the method is quite general and may be used in a wide variety of applications.
The produced approach is able to meet most of the requirements of an automatic 3D building reconstruction system. The developed system has been used in urban and suburban areas to reconstruct buildings and showed good results. Experiments were carried out on two data sets with different characteristics. The system was able to reconstruct more than 80% of the buildings and the accuracy of the reconstruction is good enough for mapping purposes.Numéro de notice : 15043 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Monographie DOI : sans En ligne : https://ncgeo.nl/downloads/53Suveg.pdf Format de la ressource électronique : URL Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=55049 Réservation

[Termes IGN] transformation de HoughRésumé : (Auteur) Creating three dimensional (3D) models of a real urban objects is an important goal in a wide variety of applications. This paper describes a method that utilizes airborne laser elevation images and aerial images for the 3-D reconstruction of urban objects. Our modeling approach uses the vertical geometric pattern analysis of elevation images. These pattern correspond to object contours and, thus enable the extraction of the object. In addition, to provide realistic textured details, textures are cut from aerial images and mapped onto 3-D models. Our textures-mapping approach can avoid geometry mismatching and enable the automatic registration to determine the most reliable correspondence between projected outlines of 3-D models and contours of real objects shown in aerial images. Edge pairs, which are matched with projected outlines, are detected from aerial images. In order to minimize mismatching, we apply the voting technique based on the generalized Hough transform. Experimental results show that 3-D reconstruction of urban objects generally successful.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) The paper presents an automatic approach for the generalisation of 3D building models with regard to the visualisation of urban landscapes. Simplified versions of such models are not only needed for level of detail structures in real-time rendering, but also for web-based 3D GIS and for the presentation on mobile computing devices. To yield more sophisticated building models compared to already known surface simplification algorithms from the field of computer vision, the presented solution is based on least squares adjustment theory combined with an elaborate set of surface classification and simplification operations. This concept allows for the integration of surface regularities into the building models which are important for visual impression. These regularities are stringently preserved over the course of the generalisation process.
