Abstract

Dispositif (100) immergé dans un milieu aqueux pour observer un objet d'intérêt présentant une couleur Ci, comprenant : une cible (102) comportant un élément d'acquisition (104), présentant une couleur Cc, une caméra (106) comportant un capteur d'image disposée pour former une image optique de l'élément d'acquisition sur le capteur d'image, selon une direction de prise d'image, dite axe de visée (X), dans lequel une distance D1, de la couleur Ci à la couleur Cc est supérieure ou égale à un seuil S1 prédéterminé, c'est-à-dire D1≥S1, le dispositif comprenant en outre : un moyen de détection de l'objet d'intérêt configuré pour détecter l'objet d'intérêt lorsque l'élément d'acquisition imagé présente une autre couleur dont une distance D, à la couleur Ci est supérieure à un seuil S2 prédéterminé, c'est-à-dire D2 ≥ S2.Device (100) immersed in an aqueous medium for observing an object of interest having a color Ci, comprising: a target (102) comprising an acquisition element (104), presenting a color Cc, a camera (106) comprising a image sensor arranged to form an optical image of the acquisition element on the image sensor, in an image-taking direction, called the viewing axis (X), in which a distance D1, of the color Ci at color Cc is greater than or equal to a predetermined threshold S1, that is to say D1≥S1, the device further comprising: a means of detecting the object of interest configured to detect the object d interest when the imaged acquisition element has another color whose distance D, to the color Ci is greater than a predetermined threshold S2, that is to say D2 ≥ S2.
