Title (EN) METHOD OF HYPERSPECTRAL MEASUREMENT
(FR) PROCÉDÉ DE MESURE HYPERSPECTRALE
Abstract:
(EN) The present disclosure provides a method of providing a hyperspectral image of a scene comprising a point (p). The method comprises providing an imaging device (10, 10') comprising a two-dimensional image sensing unit (12, 13, 14) having a spectral characteristic, which varies along at least one direction in a plane parallel with an image sensor (13), acquiring a first two-dimensional image (11) of the scene, the first image comprising the point (p), wherein the spectral content of the scene varies along the direction as a consequence of the varying spectral characteristic of the image sensing unit (12, 13, 14), moving the imaging device (10, 10') and the scene relative to each other, acquiring a second two-dimensional image (I2) of the scene, the second image comprising the point (p), wherein the spectral content of the scene varies along the direction as a consequence of the varying spectral characteristic of the image sensing unit (12, 13, 14), identifying the point (p) in the second image (I2) as a second pixel at a position (x2, y2) depicting the point (p), providing a spectral vector (S(p)) of the point, and providing an updated spectral vector (S'(p)) of the point based on an applicability vector (A(p)) of the point (p), the spectral vector (S(p)) of the point, a spectral value (z2(p)) of the second pixel and an applicability vector (B(p)) of the second pixel.
(FR) La présente invention concerne un procédé de fourniture d'une image hyperspectrale d'une scène comprenant un point (p). Le procédé comprend la fourniture d'un dispositif d'imagerie (10, 10') comprenant une unité de détection d'image bidimensionnelle (12, 13, 14) ayant une caractéristique spectrale, qui varie le long d'au moins une direction dans un plan parallèle à un capteur d'image (13), l'acquisition d'une première image bidimensionnelle (11) de la scène, la première image comprenant le point (p), dans lequel le contenu spectral de la scène varie le long de la direction en conséquence de la variation de la caractéristique spectrale de l'unité de détection d'image (12, 13, 14), le déplacement du dispositif d'imagerie (10, 10') et de la scène l'un par rapport à l'autre, l'acquisition d'une deuxième image bidimensionnelle (I2) de la scène, la deuxième image comprenant le point (p), dans lequel le contenu spectral de la scène varie le long de la direction en conséquence de la variation de la caractéristique spectrale de l'unité de détection d'image (12, 13, 14), l'identification du point (p) dans la deuxième image (I2) sous la forme d'un deuxième pixel à une position (x2, y2) représentant le point (p), la fourniture d'un vecteur spectral (S(p)) du point, et la fourniture d'un vecteur spectral mis à jour (S'(p)) du point sur la base d'un vecteur d'applicabilité (A(p)) du point (p), du vecteur spectral (S(p)) du point, d'une valeur spectrale (z2(p)) du deuxième pixel et d'un vecteur d'applicabilité (B(p)) du deuxième pixel.
