Abstract

L'invention concerne un procédé pour détecter des sites défectueux de produits semi-finis à base de fibres (3) posés sur une surface d'outillage (4), d'après lequel on détermine un profil de hauteur à l'aide d'un procédé optique de projection de lumière (6, 8), et on relève une répartition d'intensité par un éclairage supplémentaire (1 1a, 11b, 11c) et un enregistrement (8) de la zone éclairée. Des sites défectueux peuvent alors être localisés par une unité de traitement d'image (9), en fonction du profil de hauteur de la surface du produit semi-fini et de la répartition d'intensité sur celle-ci.The invention relates to a method for detecting defective sites of fiber-based semi-finished products (3) placed on a tooling surface (4), according to which a height profile is determined by means of an optical light projection method (6, 8), and an intensity distribution is detected by additional illumination (11a, 11b, 11c) and a recording (8) of the illuminated area. Defective sites can then be located by an image processing unit (9), depending on the height profile of the surface of the semi-finished product and the intensity distribution thereon.
