Abstract

L’invention concerne un système de positionnement tridimensionnel par projection laser d’un repère lumineux, notamment pour salle (1) de scanner ou radiothérapie, comprenant au moins un couple de deux émetteurs (3;4) de nappes laser (30,31;40;41) se faisant face, disposés de façon ajustable pour qu’elles s’étendent suivant des plans (P1,P2) prévus pour être coplanaires entre eux. Lesdits émetteurs (3;4) de nappe laser (30,31;40;41) sont solidaires chacun d’au moins un capteur laser (9;8), lequel est disposé dans une position déterminée relativement à la nappe (30,31;40,41) dudit émetteur, et est agencé pour détecter la nappe laser de l’émetteur lui faisant face. Le système comporte un module de communication et de commande, communiquant avec ledit au moins un capteur pour permettre un ajustement en position de la nappe laser détectée (31;41) relativement à la nappe émise (30;40) par ledit émetteur (3;4), en détectant un passage de ladite nappe détectée (31;41) sur ledit capteur lors d’un mouvement d’ajustement de ladite nappe détectée, manuel ou commandé, réalisant ainsi un réglage du tilt («inclinaison» en français) ou de translation de ladite nappe détectée. Figure pour abrégé : Fig. 5The invention relates to a three-dimensional positioning system by laser projection of a light mark, in particular for a scanner or radiotherapy room (1), comprising at least one pair of two emitters (3; 4) of laser sheets (30,31; 40; 41) facing each other, arranged in an adjustable manner so that they extend along planes (P1, P2) intended to be coplanar with each other. Said emitters (3; 4) of the laser sheet (30,31; 40; 41) are each integral with at least one laser sensor (9; 8), which is arranged in a determined position relative to the sheet (30,31 ; 40,41) of said emitter, and is arranged to detect the laser layer of the emitter facing it. The system comprises a communication and control module, communicating with said at least one sensor to allow adjustment in position of the detected laser sheet (31; 41) relative to the sheet emitted (30; 40) by said emitter (3; 4), by detecting a passage of said detected sheet (31; 41) over said sensor during an adjustment movement of said detected sheet, manual or commanded, thus carrying out a tilt adjustment (“inclination” in French) or translation of said detected web. Figure for short: Fig. 5
