Abstract

Dispositif (1) pour détecter des défauts de surface sur un objet (100). Le dispositif comprend : des moyens d'éclairage (2) configurés pour éclairer l'objet avec un premier rayonnement lumineux (L1) ayant une première direction d'éclairage (D1) ou avec un deuxième rayonnement lumineux (L2) ayant une deuxième direction d'éclairage (D2) et des moyens d'acquisition (3) configurés pour acquérir au moins une image (I0, I1, I2) de l'objet, lorsqu'il est éclairé par les moyens d'éclairage. Les moyens d'éclairage (2) comprennent une première source lumineuse polychromatique (21) configurée pour fournir le premier rayonnement lumineux (L1) et une deuxième source lumineuse polychromatique (22) configurée pour fournir le deuxième rayonnement lumineux (L2). Figure pour l’abrégé : Figure 2Device (1) for detecting surface defects on an object (100). The device comprises: lighting means (2) configured to illuminate the object with a first light radiation (L1) having a first lighting direction (D1) or with a second light radiation (L2) having a second direction d lighting (D2) and acquisition means (3) configured to acquire at least one image (I0, I1, I2) of the object, when it is illuminated by the lighting means. The lighting means (2) comprise a first polychromatic light source (21) configured to provide the first light radiation (L1) and a second polychromatic light source (22) configured to provide the second light radiation (L2).
