[Termes IGN] système de numérisation mobileRésumé : (Auteur) The rapid technological developments of the 90's have completely redefined the mapping practice as a whole. In less than a decade, digital techniques have come to outnumber the traditionally analog data acquisition and processing methods. Supported by unprecedented demand for large-volume, accurate spatial data, these new digital techniques emerged as dominant mapping technologies by the end of the decade. Technological change has also recently reached the analog camera-based aerial surveying practice, which supplies about two-thirds of spatial data for mapping and was the last stronghold of analog techniques. Two key components of this emerging technology are the electronic sensor-based digital camera and GPS/INS-based direct platform orientation. In fact, these new platform orientation systems are rapidly becoming a core component of modern airborne mapping and remote sensing systems.
This paper investigates the calibration and performance validation aspects of a GPS/INS/CM prototype system, including the digital camera calibration and the boresighting misalignment calibration of the positioning component. The calibration performance of the system is evaluated based on data collected during several test flights.Numéro de notice : C1999-065 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Communication DOI : sans En ligne : https://phowo.ifp.uni-stuttgart.de/publications/phowo99/toth.pdf Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=65829
