METHOD FOR SELECTING SURFACE POINTS FROM A CAD MODEL FOR LOCATING INDUSTRIAL 3D OBJECTS, APPLICATION OF THIS METHOD TO THE LOCATION OF INDUSTRIAL 3D OBJECTS, AND AUGMENTED REALITY SYSTEM USING 3D OBJECTS THUS LOCATED

摘要

A method for automatically selecting 3D points from a CAD model, for 3D locating of an industrial object, comprising the following steps: generating a geometric model from the CAD model; previously designating reference viewpoints from a priori knowledge of the current viewpoints of the camera; acquiring, by means of a camera, a plurality of images taken from viewpoints of interest of said object; associating each acquired image with a reference viewpoint in order to form sub-sets of images (partitions) and identifying a reference image for each partition; and selecting n 3D surface points for each partition. Use, in particular for locating industrial 3D objects, in augmented reality equipment.
