Abstract

L'invention concerne un procédé pour obtenir une image fusionnée d'une empreinte papillaire. Le procédé est mis en œuvre dans un capteur d'empreintes papillaires (110) comportant, superposés sous une surface de contact (106), un capteur optique matriciel (112), et des moyens d'éclairage (111) formés par une pluralité de dispositifs d'éclairage parallèles entre eux. Le procédé comprend les étapes suivantes : illumination de l'empreinte papillaire, les dispositifs d'éclairage étant allumés et éteints de façon à former successivement, sur la surface de contact (106), différentes figures d'éclairement constituées chacune d'au moins une bande lumineuse s'étendant sur toute la largeur (L1) d'une surface de détection du capteur optique matriciel, et acquisition par le capteur optique matriciel d'une série d'images brutes, chacune associée à l'une des figures d'éclairement ; et construction de l'image fusionnée par combinaison de pixels des images brutes, chaque série de pixel formant une ligne parallèle aux bandes lumineuses. L'invention permet d'obtenir des images de grande qualité.The invention relates to a method for obtaining a fused image of a papillary impression. The method is implemented in a papillary impression sensor (110) having, superimposed beneath a contact surface (106), a matrix optical sensor (112), and illumination means (111) formed by a plurality of lighting devices parallel to each other. The method comprises the following steps: illumination of the papillary impression, the lighting devices being switched on and off so as to successively form, on the contact surface (106), different illumination figures each consisting of at least one light strip extending over the entire width (L1) of a detection surface of the matrix optical sensor, and acquisition by the matrix optical sensor of a series of raw images, each associated with one of the illumination figures ; and constructing the merged image by combining pixels of the raw images, each pixel series forming a line parallel to the light bands. The invention makes it possible to obtain high quality images.
