Abstract

SYSTEME DE DÉTECTION HYPERSPECTRALE Le système de détection d’une particularité hyperspectrale comprend un module informatisé de construction (16) d'une image hyperspectrale tridimensionnelle (15) à partir de différentes (R0-R7) d’un plan focal. Un module de construction (16) intègre un réseau de neurones (20) qui calcule une intensité (Ιx,y,λ) de chaque voxel (Vx,y,λ) de l’image hyperspectrale tridimensionnelle (15) en fonction d'une intensité lumineuse (lR (x,y); ΙG (x,y); IB(x,y) ; IIR(x,y)) dans les images non-diffractées (17-18) et des intensités lumineuses (In( u , v )) dans les diffractions (R0-R7) de l’image compressée (14) dont les coordonnées u,v sont dépendantes des coordonnées x, y, λ du voxel (Vx,y, λ). Le système de détection comprend un module informatisé de caractérisation (21) qui détermine un indice hyperspectral à partir de l’image hyperspectrale tridimensionnelle (15).
