متن کاملÉvaluation de la vulnérabilité territoriale des enjeux environnementaux du Grand Lyon aux aléas technologiques
This study proposes a new methodology allowing a better knowledge of the territorial vulnerability of the Greater Lyon’s environmental stakes to the transport and the storage of hazardous materials. This one is mainly based on a compilation of heterogeneous spatial data and a statistical processing, based on semi-structured interviews with experts and cartographically translated with a Geograph...
متن کامل360 x 360 Mosaics
Current mosaicing methods use narrow field of view cameras to acquire image data. This poses problems when computing a complete spherical mosaic. First, a large number of images are needed to capture a sphere. Second, errors in mosaicing make it difficult to complete the spherical mosaic without seams. Third, with a hand-held camera it is hard for the user to ensure complete coverage of the sph...
متن کاملApprentissage artificiel : acquis, limites et enjeux
L’apprentissage artificiel est une activité circulaire, extrayant des connaissances à partir des observations disponibles et utilisant ces connaissances pour chercher de nouvelles informations, ou décrire différemment les observations. Dans cet article de synthèse, nous nous intéressons essentiellement à la construction de connaissances, règles ou modèles, à partir de données. Les acquis majeur...
متن کامل3d Reconstruction from 360 X 360 Mosaics 1 3d Reconstruction from 360 X 360 Mosaics
We are studying the geometry of a 360 x 360 mosaic image formation. A 360 x 360 mosaic camera model and a calibration procedure are proposed. It is shown that only one point correspondence is needed in order to acquire epipolarily rectified images. The 360 x 360 mosaic camera model is therefore determined by only one intrinsic parameter. It is shown that the relation between coordinates estimat...
