Abstract

L'invention concerne un dispositif d'identification de médicament qui, sur la base de la distance de déplacement effective d'un sachet d'emballage, détermine une limite candidate située à proximité d'un emplacement en tant que limite. Le dispositif d'identification de médicament comprend : un orifice d'insertion pour insérer des sachets d'emballage continus contenant des médicaments séparés en emballages individuels par une machine d'emballage ; un dispositif d'entraînement qui transporte les sachets d'emballage insérés à partir de l'orifice d'insertion le long d'un trajet de transport jusqu'à une zone d'imagerie ; un élément d'imagerie qui capture une image d'un sachet d'emballage contenant un médicament, dans la zone d'imagerie ; un processeur qui identifie le médicament sur la base de l'image capturée ; et un capteur de flux optique disposé sur le trajet de transport. Le processeur : entraîne le dispositif d'entraînement de telle sorte qu'une limite amont pour le sachet d'emballage est déplacée vers l'aval sur une distance définie ; calcule la distance de déplacement pour le sachet d'emballage à partir d'informations obtenues en provenance du capteur de flux optique ; et détermine, en tant que limite aval, une limite candidate aval positionnée à proximité de la distance de déplacement, dans l'image après le déplacement.
