Abstract

Un appareil d'étalonnage de caméra utilise une cible d'étalonnage associée à une source laser générant un faisceau laser qui délimite un plan d'étalonnage et qui croise le champ de vision de la caméra afin de définir une zone d'exposition d'objet. La cible d'étalonnage comprend un cadre délimitant un agencement coplanaire de points de référence ayant des coordonnées de position connues à l'intérieur d'un système de référence d'objets. Le cadre est disposé dans une position d'étalonnage de caméra dans laquelle l'agencement coplanaire des points de référence est essentiellement parallèle au plan d'étalonnage. La cible inclut un agencement d'éléments réfléchissant la lumière qui dépassent de l'agencement des points de référence dans une direction quasi-perpendiculaire à celui-ci de manière à se prolonger à l'intérieur de la zone d'exposition de l'objet afin de permettre à la caméra de capturer une image formée par des parties éclairées des éléments réfléchissant la lumière. L'appareil comprend également des processeurs d'images programmés selon un modèle de caméra étalonné pour associer des coordonnées de position du système de référence d'objets aux coordonnées correspondantes d'un système de référence d'images.
