Embodiment approach

[0073] 1) Level the aircraft, that is, adjust the horizontal and longitudinal directions of the aircraft. The method is: arrange two measuring points symmetrically on the left and right wings of the aircraft. Arrange two measuring points in the direction of the aircraft fuselage, and the height difference between the two points will reach longitudinal leveling within 0.5mm. Secondly, place the laser tracker at the lower station position, and the measurement coordinate system of the laser tracker and the assembly of the lower station Coordinate system 1. Here, the measurement coordinate system of the laser tracker refers to the spatial coordinate system automatically established by default after the laser tracker is turned on, and the assembly coordinate system of the next station refers to the one defined by the designer according to the layout of the general assembly of the aircraft on site. The spatial coordinate system, the method of unifying the two is: by measuring several...

Abstract

The invention discloses an HUD (Heads-Up Display) digitized boresight method applied to plane general assembly, comprising the following steps of: (1) leveling a plane, arranging a laser tracker on a lower station, unifying a measuring coordinate system of the laser tracker with an assembly coordinate system of the lower station and centering a water bubble on an HUD boresight device; (2) measuring a No. 2 point and a No. 12 point by utilizing the tracker and constructing a symmetric axis of the plane in a computer; (3) moving the tracker to an upper station and unifying a measuring coordinate system of the tracker with an assembly coordinate system of the upper station; (4) finishing the measurement of a target on the boresight device; (5) calculating and displaying the deviations of theboresight device relative to the construction plane and the symmetric axis of the plane through patterns and finishing HUD boresight if satisfying the requirement or else continuing the HUD boresight; and (6) manually adjusting the mounting position of the boresight device according to the prompts of the computer and repeating the steps (4) and (5) until satisfying the requirement. The invention can effectively improve the boresight precision and the efficiency, lessen the reliance of boresight operation on the size of a field space, and improve the automated and integrated level of plane general assembly.

Description

technical field [0001] The invention relates to a target calibration method, in particular to a HUD digital target calibration method applied to aircraft general assembly. Background technique [0002] The head-up display is a set of photoelectric display equipment with more functions than the optical sight. Its positioning and installation accuracy will directly affect the accuracy of the aircraft's fire control system. Therefore, the installation and positioning of the HUD must be calibrated to ensure the accuracy of the fire control of the aircraft system. Over the years, the head-up display calibration method in my country still follows the traditional optical calibration method, which has a low degree of automation, poor reliability of measurement data, and a large space occupied by the work site, which seriously inhibits the improvement of calibration accuracy and the accuracy of calibration. Efficiency improvement. Contents of the invention [0003] The object of t...
