Abstract

PROCEDE DE MES URE AUTOMATIQUE D’UN ECART ENTRE DEUX PIECES L’invention concerne un procédé de mesure automatique d’un écart (4) entre deux pièces (2 , 3) caractérisé en ce qu’il comprend les étapes suivantes : orientation d’un objectif (10, 11) d’axe X vers l’écart (4) à mesurer,acquisition d’une image de l’écart,traitement de l’image pour détecter un bord (210, 310) de chacune des deux pièces (2, 3),mesure de l’écart (4). Il est ainsi possible d’avoir une mesure exacte de l’écart de façon fiable. La qualité de l’étape d’acquisition permet de simplifier l’étape de traitement d’image Figure à publier avec l’abrégé : Figure 6
