Abstract

La présente invention concerne un procédé et un dispositif pour le traitement local d'une surface irrégulière (S), non métrique et soumise à des mouvements accidentels, qui permet d'effectuer un traitement ponctuel et pratiquement automatique et comprend les phases consistant à : faire l'acquisition d'une image numérique en temps réel (10) de la surface (S), la diviser en un ensemble de cellules élémentaires ou de pixels selon une résolution prédéterminée et associer à chaque pixel une valeur de référence ; identifier sans ambiguïté la zone cible (T) à traiter et un ou plusieurs points de repère (R), en associant un ensemble défini de pixels ; prédisposer une lampe témoin ; calculer le vecteur de déplacement entre la lampe témoin et les points de traitement, en utilisant comme système de référence les points de repère (R) qui sont visibles à travers une zone de visualisation (F), et déplacer la lampe témoin selon le vecteur de déplacement, en itérant le processus jusqu'à ce que la superposition entre la lampe témoin et le point de traitement soit obtenue ; appliquer le traitement ponctuel sur le point de traitement ; et répéter les phases précédentes pour chaque point de traitement jusqu'à ce que la zone cible (T) tout entière ait été traitée ; et chaque cible jusqu'à ce que le résultat voulu soit atteint.
