METHOD AND SYSTEM FOR DUAL HARMONIZATION OF A HEAD-UP DISPLAY SYSTEM WITH AN INERTIAL ATTITUDE DEVICE REMOVABLE IN THE COCKPIT

摘要

A method of dual harmonization of a head-up display system worn to conform the display of piloting information of an aircraft on a display with the real outside world comprises: - an acquisition step (206) N measurements Ki for detecting head posture by a series of sights Vi corresponding to images oriented along orientations Oi of the same photograph taken by a camera, integral and aligned with the inertial attitude device D3, then - a step (208) of joint calculation of the relative orientation matrices M01 and M23 as joint solutions of the system of dual harmonization equations Ûi = G. Ki. D, i varying from 1 to N, in which Ûi is the transpose of the matrix M (image (i) / 0) of relative orientation of the image (i) of rank i with respect to the display D0, with M01 and M23 equal respectively to the right and left matrices D and G. A head-up display system carried is configured to implement said dual harmonization method.
