Title
(DE) VORRICHTUNG ZUR INSPEKTION VON RISSEN IN BETONSTRUKTUREN UND RISSINSPEKTIONSVERFAHREN
(EN) CONCRETE STRUCTURE CRACK INSPECTION DEVICE AND CRACK INSPECTION METHOD
(FR) DISPOSITIF ET PROCEDE DE CONTROLE DES FISSURES SUR UN OUVRAGE EN BETON
Abstract
(EN) A crack inspection device (6) for a concrete structure (1) includes: storage means for storing raster data obtained by imaging a surface (2) of the concrete structure (1) having a crack (3); conversion means for performing raster vector conversion on the data obtained by digitizing the raster data; data superimposing means for superimposing the vector data of the crack (3) obtained by the conversion means on the graphic data of the surface (2) of the concrete structure (1) while matching the coordinates; and output means for outputting the superimposed data obtained by the data superimposing means.
(FR) La présente invention concerne un dispositif d’inspection des fissures (6) sur un ouvrage en béton (1) comprenant : des moyens pour stocker des données de trame obtenues par l’imagerie d’une surface (2) de l’ouvrage en béton (1) présentant une fissure (3) ; des moyens de conversion pour effectuer une conversion d’un vecteur de trame sur les données obtenues en numérisant les données de trame ; des moyens pour superposer les données vectorielles de la fissure (3) obtenues par les moyens de conversion sur les données graphiques de la surface (2) de l’ouvrage en béton (1) tout en respectant les coordonnées ; et des moyens pour afficher les données superposées obtenues par les moyens de superposition.
