The present invention relates to the field of measuring apparatuses systems allowing for measuring presence, position and/or shape of an object placed on a carrier and a method for such measuring. The measuring apparatus comprises at least one light source arranged to illuminate said object and said carrier with incident light; at least one sensor placed on a predetermined distance from said at least one light source and arranged to repeatedly measure said object and said carrier by detecting reflected light from said object and said carrier when said carrier is moved in said direction of movement and to convert the detected light into electrical signals; an image-processing unit arranged to use the electrical signals and obtain a three-dimensional sub- image of each of the measurements of said object and said carrier and to obtain a three-dimensional image of said object and said carrier from one or more of said obtained sub-images; and, a calculating unit arranged to determine the presence, position and/or shape of said object on said carrier from said three-dimensional image.

L'invention concerne le domaine des appareils de mesure dans des systèmes de distribution permettant de mesurer la présence, la position et/ou la forme d'un objet placé sur un support, ainsi qu'un procédé associé à cette mesure. L'appareil de mesure comprend au moins une source de lumière conçue pour éclairer ledit objet et ledit support par de la lumière incidente, au moins un capteur placé à distance prédéterminée de ladite source de lumière et conçu pour mesurer en continu ledit objet et ledit support par détection de la lumière réfléchie par ledit objet et ledit support quand ce dernier est déplacé dans ledit sens de déplacement et convertir la lumière détectée en signaux électriques, un ensemble de traitement d'image conçu pour mettre en application les signaux électriques et obtenir une sous-image tridimensionnelle de chacune des mesures dudit objet dudit support et obtenir une image tridimensionnelle dudit objet et dudit support à partir d'une ou plusieurs desdites sous-images obtenues, enfin un ensemble de calcul conçu pour déterminer la présence, la position et/ou la forme dudit objet placé sur ledit support à partir de ladite image tridimensionnelle.
