Title (EN) METHOD FOR MEASURING 3D COORDINATES OF A SURFACE WITH A PORTABLE ARTICULATED ARM COORDINATE MEASURING MACHINE HAVING A CAMERA
(FR) PROCÉDÉ PERMETTANT DE MESURER LES COORDONNÉES 3D D'UNE SURFACE À L'AIDE D'UNE MACHINE DE MESURE DE COORDONNÉES PORTATIVE À BRAS ARTICULÉ DOTÉE D'UN APPAREIL DE PRISE DE VUES
Abstract:
(EN) A method for measuring three-dimensional (3D) coordinates of a surface includes providing a manually positionable articulated arm portion having opposed first and second ends, providing a measurement device coupled to the first end, the measurement device including a camera having a lens and a photosensitive array and moving the camera to first and second positions and orientations to capture first and second images. Based on data from the camera, a first set of cardinal points common to the first and images and the second images are used to form a 3D coordinates that describe the surface.
(FR) La présente invention concerne un procédé qui permet de mesurer les coordonnées tridimensionnelles (3D) d'une surface et qui consiste : à utiliser une partie bras articulé positionnable manuellement et comportant des première et seconde extrémités situées en regard l'une de l'autre; et à utiliser un dispositif de mesure couplé à la première extrémité, ce dispositif de mesure comprenant un appareil de prise de vues qui est muni d'une lentille et d'une barrette photosensible et déplaçant l'appareil de prise de vues vers une première et une seconde position et selon une première et une seconde orientation afin de capturer une première et une seconde image. En fonction des données provenant de l'appareil de prise de vues, un premier ensemble de points cardinaux commun aux première et seconde images est utilisé pour créer les coordonnées 3D qui décrivent la surface.
