Title
(EN) INDIVIDUAL IDENTIFICATION SYSTEM
(FR) SYSTÈME D'IDENTIFICATION INDIVIDUELLE
(JA) 個体識別システム
Abstract
(EN)
An individual identification system includes: a storage means that associates the surface of a reference object with characterization data and stores an imaging parameter; an acquisition means that, when data is input for characterizing the surface of a comparison object, calculates the degree of similarity of the input data with the data stored in the storage means, and acquires from the storage means the imaging parameter to be applied to the comparison object, on the basis of the calculated degree of similarity; a condition setting means that sets imaging conditions determined by the acquired imaging parameter; an imaging means that acquires an image of the surface of the comparison object, under the set imaging conditions; an extraction means that extracts a feature amount from the acquired image; and a comparison means that compares the extracted feature amount and a registered feature amount.
(FR)
L'invention concerne un système d'identification individuelle comprenant : un moyen de mémorisation qui associe la surface d'un objet de référence à des données de caractérisation et qui mémorise un paramètre d'imagerie ; un moyen d'acquisition qui, lorsque des données sont entrées à des fins de caractérisation de la surface d'un objet de comparaison, calcule le degré de similarité des données d'entrée avec les données mémorisées dans le moyen de mémorisation, et acquiert, à partir du moyen de mémorisation, le paramètre d'imagerie à appliquer à l'objet de comparaison, sur la base du degré de similarité calculé ; un moyen de définition de conditions qui définit des conditions d'imagerie déterminées par le paramètre d'imagerie acquis ; un moyen d'imagerie qui acquiert une image de la surface de l'objet de comparaison, dans les conditions d'imagerie définies ; un moyen d'extraction qui extrait une quantité de caractéristiques de l'image acquise ; et un moyen de comparaison qui compare la quantité de caractéristiques extraite et une quantité de caractéristiques enregistrée.
