Abstract

Procédé de mesure de la localisation d'un objet (5) dans un espace observé par un système fixe d'observation (1) relié à une unité de traitement (4), pour générer une image composée d'une matrice de pixels, ledit objet (5) étant pourvu d'une mire (8). La mire (8) comprend au moins un motif périodique à deux dimensions et on procède à un traitement numérique de l'image du motif pour générer une image contenant un premier réseau et une image contenant un deuxième réseau qui sont analysées numériquement pour calculer la position de la mire dans la matrice de pixels.
