Abstract

Procédé de contrôle non destructif d’une pièce, par exemple une pièce aéronautique, système, produit programme d’ordinateur, pièce aéronautique et aéronef, le procédé comprenant une étape d’acquisition de plusieurs images de la pièce à différents instants d’acquisition respectifs, chaque image comprenant des pixels associés respectivement à des zones de la pièce, une valeur du pixel étant représentative d’une caractéristique de la zone, une étape d'association de chaque zone à un vecteur ayant des composantes comprenant les valeurs du pixel aux différents instants d’acquisition, une étape de détermination de paramètres de référence, associés à au moins une zone, par moyennage du vecteur de zones voisines de la zone d’une pièce de référence et une étape de comparaison du vecteur de la zone avec les paramètres de référence pour détecter une anomalie sur la zone. Figure pour l’abrégé : Fig. 1Method for non-destructive testing of a part, for example an aeronautical part, system, computer program product, aeronautical part and aircraft, the method comprising a step of acquiring several images of the part at different respective acquisition times , each image comprising pixels associated respectively with zones of the room, a value of the pixel being representative of a characteristic of the zone, a step of associating each zone with a vector having components comprising the values of the pixel at the different acquisition instants, a step of determining reference parameters, associated with at least one zone, by averaging the vector of zones neighboring the zone of a reference part and a step of comparing the vector of the zone with the parameters reference to detect an anomaly in the area.
