Definitions

  • the cameras can be mounted on a portal, under which the workpiece is transported, and thus capture it from various directions that may be difficult for an employee to access.
  • the gesture to be detected can be a pointing at the defect, a look at a predetermined object in the vicinity of the workpiece or a processing of the defect by the user of the VR glasses.
  • Fig. 1 is a schematic representation of the system according to the invention.
  • Vehicle bodies 1 are transported by the drive means 2 through a scanner 3, which comprises a portal 5 equipped with various cameras 4.
  • the cameras 4 are aligned with an interior of the portal 5 in order to detect the outer surfaces of the bodies 1 transported through.
  • Fig. 2 shows schematically the image that the employee 1 1 presents through the VR glasses 10.
  • the VR glasses 10 comprise one in a manner known per se

Abstract

L'invention concerne un système d'assistance d'un usinage de surfaces sur une pièce (1). Le système comprend : un scanner (3) servant à identifier et à localiser des défauts sur la surface d'une pièce (1) ; un instrument d'édition mobile par rapport au scanner (3) sous la forme d'un casque de réalité virtuelle (11) servant à éditer les positions, sur lesquelles le scanner (3) identifie un défaut ; des moyens (6, 9) servant à détecter la position et l'orientation du casque de réalité virtuelle (10) par rapport à la pièce (1) ; et un processeur graphique (12), qui est mis au point pour afficher, sur une image s'affichant dans le casque de réalité virtuelle (10), une information concernant le défaut sur ou à proximité d'une ligne de vision (15) s'étendant entre l'œil d'un utilisateur (11) du casque de réalité virtuelle (10) et le défaut.
