Abstract
La présente invention concerne un procédé de détection de défauts sur au moins une couche de poudre de fabrication additive déposée sur une zone de travail, ledit procédé comprenant, avant une consolidation sélective de la couche de poudre, la mise en œuvre par des moyens de traitement des étapes suivantes :i. acquisition d’une image de la couche de poudre de fabrication additive déposée,ii. découpage d’au moins une zone de ladite image en une pluralité de tuiles, ces tuiles assemblées les unes aux autres bord-à-bord permettant de reconstituer la zone découpée de ladite image,iii. traitements des tuiles en parallèle en appliquant à chacune un modèle de classification configuré pour détecter la présence d’un défaut de mise en couche dans une tuile,iv. génération, en fonction des résultats des traitements des tuiles en parallèle, d’un signal caractérisant un défaut dans la couche de poudre et/ou déclenchant une action corrective.
