SYSTEME DE VISUALISATION "TETE HAUTE" POUR AERONEF COMPORTANT UN DISPOSITIF DE LECTURE SANS CONTACT DES PARAMETRES D'HARMONISATION AVEC L'AERONEF

The general field of the invention is that of "Head-Up" display systems for aircraft, comprising at least one display device (2) intended to be worn on the head of a user and a posture detection device comprising a first optical assembly (3) rigidly attached to the display device and a second optical assembly (4) consisting of optical detection patterns rigidly attached to the cockpit of said aircraft, said first optical assembly comprising a camera (6). The "Head-Up" display system according to the invention comprises a device for contactless reading of parameters for geometrical harmonisation of the display system with the aircraft, said contactless reading device comprising a harmonisation pattern (5) comprising an optical coding of said harmonising parameters and electronic identification means of said optical coding when it is filmed by the camera, said harmonisation pattern being disposed in the aircraft cockpit.
