Abstract

L'invention se rapporte à un dispositif (3) et un procédé d'acquisition d'images. Le dispositif (3) comprend un appareil photographique (31) relié à un canon (32) pour estimer, via un logiciel de traitement d'images, un pourcentage d'ouverture d'orifices d'une peau de panneau acoustique pour ensemble propulsif d'aéronef. Le dispositif (3) est agencé pour empêcher le passage de la lumière environnante dans le canon (32) et comprend un moyen d'éclairage (33) interne apte à contrôler la luminosité de la peau à photographier.
