Title (EN) QUANTITATIVE SURFACE MEASUREMENTS BY COMBINING IMAGE AND HEIGHT PROFILE DATA
(FR) MESURES QUANTITATIVES DE SURFACE PAR LA COMBINAISON DE DONNÉES D'IMAGE ET DE DONNÉES DE PROFIL DE HAUTEUR
Abstract:
(EN) A method of constructing a three-dimensional model of an internal surface of a tubular structure comprises obtaining image data from an area of the internal surface of the structure, obtaining measured height profile data from the internal surface in a plurality of sub-regions of the area, for example using a multi-finger caliper tool, determining image properties from the image data, correlating the measured height profile data with the image properties in the sub-regions, and constructing expected height profile data for at least part of the area outside the sub-regions using the correlated measured height profile data and image properties.
(FR) L'invention concerne un procédé de construction d'un modèle tridimensionnel d'une surface interne d'une structure tubulaire comprenant l'obtention de données d'image provenant d'une zone de la surface interne de la structure, l'obtention de données de profil de hauteur mesurées provenant de la surface interne dans une pluralité de sous-régions de la zone, par exemple à l'aide d'un outil de compas d'épaisseur à pieds multiples, la détermination de propriétés d'image à partir des données d'image, la corrélation des données de profil de hauteur mesurées avec les propriétés d'image dans les sous-régions, et la construction de données de profil de hauteur attendues pour au moins une partie de la zone à l'extérieur des sous-régions à l'aide des données de profil de hauteur mesurées et des propriétés d'image corrélées.
