Abstract
The present invention relates to a device (1) for positioning a mock-up (2). The device comprises supports (3, 4) suitable for holding the mock-up in a variable position which is controllable in attitude and/or altitude relative to an illumination axis (I-I'). The mock-up is held by two pairs of top wires (6) and by two pairs of bottom wires (7). These four pairs of wires are mounted at their opposite ends on tensioning means (8) fixed to the opposite ends of the supports (3, 4) and intended to adjust the tensions and the lengths of the wires as a function of a desired attitude and/or a desired altitude for the mock-up. The device also includes control means (9) for controlling the angular positions of the supports (3, 4), and cameras connected to processor means for measuring the real position and attitude of the mock-up.
