Abstract (en)
[origin: FR2910123A1] The method involves implementing four projection axes of a light fringe on an object (6), where an origin of each projection axis is considered as an illumination point disposed at a virtual tetrahedron. Four shooting points are arranged along four shooting axes (7), where each shooting axis is a median of the tetrahedron. A set of images containing a portion of outer surfaces of the object is illuminated by the illumination points of the projection axis. The images illuminated by the illumination points are captured by a charge coupled device camera (8). An independent claim is also included for a system for 3-dimensional measuring of an outer surface of an object.
