Title
(EN) PROJECTION DEVICE FOR DISPLAYING CONSTRUCTION PLANS
(FR) DISPOSITIF DE PROJECTION PERMETTANT D'AFFICHER DES PLANS DE CONSTRUCTION
Abstract
(EN)
A projection device for displaying construction plans comprises a projector head having projection optics, a laser module, a first mirror galvanometer redirecting incident light from the laser module toward a second mirror galvanometer that redirects further the incident light toward the projection optics. A memory device stores one or more construction plans. A controller operatively connected to the laser module, the two mirror galvanometers, and the memory device chooses a construction plan to be displayed from the memory device, selectively activates the laser module, and selectively causes the first and second mirror galvanometers to follow a path defined by the chosen construction plan concurrently with the selective activation of the laser module so that the incident light redirected toward the projection optics selectively forms a projection of the construction plan on a construction site.

L'invention concerne un dispositif de projection permettant d'afficher des plans de construction et comprenant une tête de projecteur comportant une optique de projection, un module laser, un premier galvanomètre à miroir redirigeant la lumière incidente provenant du module laser vers un second galvanomètre à miroir qui redirige la lumière incidente vers l'optique de projection. Un dispositif de mémoire stocke au moins un plan de construction. Un dispositif de commande connecté fonctionnellement au module laser, aux deux galvanomètres à miroir et au dispositif de mémoire choisit un plan de construction à afficher à partir du dispositif de mémoire, active sélectivement le module laser et amène sélectivement les premier et second galvanomètres à miroir à suivre un trajet défini par le plan de construction choisi, simultanément à l'activation sélective du module laser, afin que la lumière incidente redirigée vers l'optique de projection forme sélectivement une projection du plan de construction sur un site de construction.
