Abstract

L'invention concerne un système d'aide à la détection d'un défaut (DF) de surface d'une paroi (PLV) d'un objet (V). Un tel système comporte un ou plusieurs dispositifs de capture (1, 1'), comprenant un capteur matriciel (C) et un premier, voire un deuxième, éléments lumineux (EL1, EL2) pour projeter sur la paroi (PLV) dudit objet (V) respectivement un premier motif hétérogène et un deuxième motif homogène. De tels dispositifs de capture (1, 1') coopèrent avec une unité de traitement (11) agencée pour produire à partir de représentations numériques (R(t), RW(t)) délivrées par ledit capteur matriciel (C) de chaque dispositif de capture (1, 1') une représentation composite ou fusionnée de ladite paroi (PLV) mettant en exergue un éventuel défaut (DF) de surface.The invention relates to a system for assisting in the detection of a defect (DF) in the surface of a wall (PLV) of an object (V). Such a system comprises one or more capture devices (1, 1 '), comprising a matrix sensor (C) and a first, or even a second, light elements (EL1, EL2) for projecting on the wall (PLV) of said object ( V) respectively a first heterogeneous unit and a second homogeneous unit. Such capture devices (1, 1 ') cooperate with a processing unit (11) arranged to produce from digital representations (R (t), RW (t)) delivered by said matrix sensor (C) of each device capture (1, 1 ') a composite or fused representation of said wall (PLV) highlighting a possible surface defect (DF).
