Abstract

La présente divulgation porte sur la description d'une méthode et d'un appareil portatif de balayage pour le balayage tridimensionnel d'un objet. L'appareil portatif à auto-référence comprend les éléments qui suivent. Une source lumineuse pour éclairer des marqueurs rétroréfléchissants, ces marqueurs rétroréfléchissants occupant des positions fixes sur l'objet ou autour de celui-ci; une caméra photogrammétrique à haute résolution, un projecteur de trace pour fournir une trace projetée sur la surface de l'objet; au moins une paire de caméras de base coopérant avec les sources lumineuses, la trace projetée et au moins une partie des marqueurs rétroréfléchissants étant apparents sur les images bidimensionnelles; une carcasse pour maintenir en place tous les éléments dans l'appareil portatif, la carcasse étant pourvue d'une poignée, et cette carcasse assurant le support le mouvement libre de l'appareil de balayage par un utilisateur.
