Abstract

Des méthodes sont décrites pour mettre en uvre automatiquement la compensation atmosphérique dune image multi ou hyper-spectrale. Une méthode consiste à transformer au moins deux éléments dextrémité extraits dune image en une réflectance au sol. La transformation peut être approximative et/ou uniquement dans certaines bandes spectrales afin de réduire le temps de traitement. Un composant dappariement est ensuite situé dans une bibliothèque spectrale pour chacun des éléments dextrémité extraits. Des valeurs de gain et de décalage sont ensuite calculées à laide des paires de composantes délément dextrémité extraites et de bibliothèque spectrale extraites appariées. Au moins une partie de limage est ensuite compensée à laide des valeurs de gain et de décalage calculées. Une autre méthode utilise au moins un élément dextrémité extrait de limage et un niveau du noir. Des méthodes pour compensation atmosphérique utilisant la teneur en vapeur deau de pixels sont également décrites. De plus, les méthodes de correction dombre dimages hyperspectrales et multispectrales sont décrites.
