Title (EN) IMPROVED METHOD FOR CONTROLLING THE POLISHING OF GEMSTONES
(FR) PROCÉDÉ AMÉLIORÉ DE COMMANDE DU POLISSAGE DE PIERRES PRÉCIEUSES
Abstract:
(EN) Method for controlling the polishing of a gemstone, comprising: obtaining a three-dimensional model of the gemstone; fixing the gemstone in a dop, wherein an initial facet to be polished is aligned; obtaining at least one image of the initial facet while the gemstone is; based on the obtained at least one image and the obtained three-dimensional model, determining at least first setting parameters for a first planned facet positioned between the initial facet and a desired final polished facet; setting the dop for obtaining a polished gemstone having a polished facet approaching the first planned facet; obtaining of at least one image of the polished; based on the obtained at least one image of the polished facet and the three-dimensional model, determining at least further setting parameters for a further planned facet; setting the dop for obtaining a polished gemstone having a polished facet approaching the further planned facet.
(FR) L'invention concerne un procédé pour commander le polissage d'une pierre précieuse, comprenant les étapes consistant : à obtenir un modèle tridimensionnel de la pierre précieuse ; à fixer la pierre précieuse dans un dop, une facette initiale à polir étant alignée ; à obtenir au moins une image de la facette initiale pendant que la pierre précieuse est polie ; sur la base de ladite image obtenue et du modèle tridimensionnel obtenu, à déterminer au moins des premiers paramètres de réglage pour une première facette planifiée positionnée entre la facette initiale et une facette polie finale souhaitée ; à régler le dop pour obtenir une pierre précieuse polie présentant une facette polie s'approchant de la première facette planifiée ; à obtenir au moins une image de la pierre précieuse polie ; sur la base de ladite image obtenue de la facette polie et du modèle tridimensionnel, à déterminer au moins d'autres paramètres de réglage pour une autre facette planifiée ; à régler le dop pour obtenir une pierre précieuse polie présentant une facette polie s'approchant de l'autre facette planifiée.
