[Termes IGN] SMOSRésumé : (Auteur) MIRAS is more than just the payload of SMOS. It is a radio telescope pointed towards Earth, an instrument that has challenged the fundamental theories of radio astronomy, and made a major contribution to science even before being launched.

[Termes IGN] TautavelRésumé : (Auteur) We are currently developing a vision-based system aiming at automatically generating in situ ultra-high resolution mosaics in previously unknown, complex and unstructured underground environments. Nowadays, image stitching algorithms present several limitations when dealing with unstructured environments. The most important to our concern is the ability to deal with feature-less areas. In this paper we describe an automatic on line Gigapixel mosaicing system capable to deal with the absence of reliably detectable and trackable features. The input of our algorithm is a pose-annotated sequence of high-resolution images acquired from a common optical center by a calibrated pantilt motorized digital camera unit. The proposed mosaïcing system is powered by a global-to-local pairwise image alignment which recovers the rotations relating the overlapping images in a coarse-to-fine approach. The local motion procedure outputs a list of locally matched anonymous features which are later injected in a bundle adjustment engine for multi-view fine alignment. The proposed algorithm combines the state of the art mosaicing techniques in a complementary and efficient fashion providing an environment-independent solution for the image mosaicing task. The final output of the algorithm is a Gigapixel spherical mosaic rendering. Tests on real data acquired in a prehistorical cave (Tautavel Cave, France) illustrate mosaicing examples obtained from several hundreds of high-resolution images.

[Termes IGN] traitement d'imageRésumé : (Auteur) Progress in automated photogrammetric DEM generation is presented. Starting from the procedures and the performance parameters of automated photogrammetric DEM generation, the results of some practical tests with large scale images are presented. The DEMs are derived from images taken by a digital large-frame aerial camera and checked by reference data of superior accuracy. In average, a vertical accuracy of ó h = 13 cm or 0.20 per thousand of the mean flying height above mean terrain has been achieved. Some recent innovations in digital large-frame cameras and in the processing software give hope for even better results. In comparison with results from film-based cameras, it can be stated that both technologies are able to produce very dense and accurate DEMs. Copyright ASPRS Numéro de notice : A2009-009 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Article DOI : 10.14358/PERS.75.1.87 En ligne : https://doi.org/10.14358/PERS.75.1.87 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=29639

[Termes IGN] télémétrie laser terrestreRésumé : (Auteur) The 8th Conference on Laser Scanning & Digital Aerial Photography was held, as in the previous two years, at the president Hotel in Moscow on 10th and eleventh December 2008. The Conference attracted over 200 participants, principally from Russia and CIS countries. However there were 20 or so participants from western countries, mainly from the system and software suppliers, most of whom made presentations at the conference, besides promoting their products in the conference exhibition.
