METHOD AND SYSTEM FOR DUAL HARMONIZATION OF A HIGH-DOOR HEAD DISPLAY SYSTEM TO REALIZE AIRCRAFT DRIVING INFORMATION DISPLAY WITH THE REAL WORLD OUTSIDE

摘要

A dual harmonization method of a head-up display system carried to conform the display of flight information of an aircraft with the external real world comprises: - a step (206; 306) of acquisition of N measurements of head postures by a series of different sight Vi which each align a sighting pattern, located at a different fixed position Pi on the display DO with a target vector function of the position Pi, then - a step ( 208; 308) for calculating the relative orientation matrix M01 between the display D0 in a tilted engagement position in the field of view and the first tracking element D1 as the right matrix D solution of the system of equations d dual harmonization G.KiD.xi = y0 for i varying from 1 to N, the vector y0 denoting the vector in the inertial frame of the platform corresponding to the target target point in the outside real world and being unknown; and the left matrix G being the relative orientation matrix M23 between the second fixed element D2 and the attitude inertial device D3, which is potentially incorrect but assumed to be constant as a function of time, and which, when unknown, requires at least four measures Ki. A head-up display system is configured to implement said dual harmonization method.
