[Termes IGN] théorie de Dempster-ShaferIndex. décimale : 33.30 Photogrammétrie numérique Résumé : (Auteur) Information gained from aerial and satellite images is widely used in industry and public life. Thus, the inter-national community supports big efforts to automate the image analysis process and to increase the reliability of the results. In this context we aim to develop a knowledge based system for the interpretation of monocular aerial images. By using knowledge gained from topographical maps, the system shall be able to automatically build a description of complex urban scenes. As input data large scale colour aerial images, digitised to a pixel size of 30 cm x 30 cm on the ground, and topographical maps with scale 1:5000 are used.
A central component of the system are the object models. In order to adequately represent the available knowledge and to assure the flexibility of the system we build several models. They are arranged in a model hierarchy and we represent them in semantic networks. The most general model is the generic scene model. From it we derive the map-domain model and the image-domain model. They describe the projection of a scene in a topographic map and in an aerial image, respectively.
The models are used in the four steps of our analysis process. In the first step the map-domain model is used to analyse the map. As result, a structural description of the scene, as far as it is represented in the map, is built. As soon as digital maps already provide a structural scene description, this step becomes obsolete. One can expect that such maps will be available in the future. In the second step the scene description gained after the first step is automatically combined with the image-domain model. As result one obtains a model which is specific for the current scene to be analysed. In the third step line segments and regions are calculated from the aerial image. The line segments are calculated with a gradient based procedure. The regions are gained by segmenting J;he image with a region growing procedure. Starting points for the region growing are extracted from the specific model. In the segmentation process we use a new homogeneity predicate based on the a-posteriori probability of the pixels to fulfil a region model. The proposed region models cover most of the practical relevant cases and allow an efficient computation of the homogeneity predicate.
The specific model is used again in the fourth step. This step is performed in three phases. In the first phase the objects represented in the map are verified in the image data. The knowledge gained in this phase is used as context in the following phases. In the second phase the description of the verified objects is improved by extracting additional attributes from the image data. Finally, in the third phase those areas of the scene are addressed, for which the map does not provide any information or for which in the first phase the verification has failed.
The analysis is performed in all three phases by using the same problem independent control algorithm. It implements the analysis as a search process. We use the E-A*-algorithm to conduct this search. The merit functions for the search algorithm have been embedded in the Dempster-Shafer-theory of evidence and to calculate them we have developed a new method to propagate evidence in an hierarchical environment. We discuss the performance of our system and show its applicability not only for the recognition of single object classes or single objects, but for the recognition and reconstruction of buildings of different size and shape, of parking areas, cars and vegetation areas.Numéro de notice : 28013 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Thèse étrangère Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=63360 Réservation

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) When a human cartographer designs a map, the symbols represent objects in a way that attempts to convey geographic process occurring at a given scale. The skill is in abstracting patterns of process and representing them in a context at an appropriate scale. The cartographer conveys the essence of the phenomenon by capturing the essential characteristics of a feature. In order for automated cartographic systems to match this subtlety in design and this ability to characterize, they must have cartometric techniques that enable the same abstraction of pattern to take place; techniques that take into account the phenomenological aspects of features. This article utilizes an algorithm for urban space pattern analysis and illustrates how it can be applied to capture the essence of urban settlement in order to generate objective, intermediate design solutions for the representation of urban settlement at a range of scales. Such an algorithm is considered to be one of a growing set of generalization operators that need to be developed as part of a knowledgebased cartographic expert system. The article begins with a description of a "Iine of sight" pattern analysis algorithm applied to road networks and then demonstrates how the algorithm can be used to derive hierarchies of meaningful patterns-patterns which capture the character and extent of urban areas appropriate to a given scale. The article concludes with a discussion of how such techniques may be utilized for automated cartographic generalization of urban space.
