Abstract

L'invention concerne un procédé d'étalonnage géométrique d'une première caméra (C) d'un système de détermination d'images tridimensionnelles comprenant la projection par un dispositif de projection (P) d'un faisceau lumineux sur une mire d'étalonnage (30) comprenant des fils réfléchissant au moins partiellement le faisceau lumineux et fixés à un support, le support délimitant une ouverture traversante, chaque fil comprenant une portion tendue en vis-à-vis de l'ouverture traversante.The invention relates to a method for geometrical calibration of a first camera (C) of a system for determining three-dimensional images comprising the projection by a projection device (P) of a light beam on a calibration target. (30) comprising wires reflecting at least partially the light beam and fixed to a support, the support delimiting a through opening, each wire comprising a stretched portion opposite the through opening.
