Airborne head-up vision system target calibration method and target calibration equipment

Abstract

The invention belongs to the field of aviation equipment calibration equipment, and relates to an airborne head-up vision system target calibration method and target calibration equipment. According to the method and the equipment disclosed in the invention, the precision of the airborne head-up vision system is improved through the following three ways: firstly, multiple times of use of a boresighting reference is prevented in the boresighting process and is consistent with the use frequency of boresighting head-up display equipment, and therefore introduced extra errors are prevneted; secondly, the precision of the airborne head-up display equipment in a limited operating distance is improved in a manner of aligning the optical axes of the airborne head-up display equipment and the airborne visual equipment in a limited distance; thirdly, parallax caused by different mounting positions of the airborne head-up display equipment and the airborne visual equipment on the airplane is caused.

Description

technical field [0001] The invention belongs to the field of calibrating equipment for aviation equipment, and relates to a target calibration method and target calibration equipment for an airborne head-up visual system. Background technique [0002] The airborne head-up visual system is based on visual system (such as enhanced vision system (hereinafter referred to as EVS), low-light camera, etc.) and head-up display products (such as head-up display (hereinafter referred to as HUD), head-mounted ) is a new type of display system born from the evolution of head-up display technology. In order to meet the needs of supporting aircraft precision approach, the current industry's demand for the accuracy of the airborne head-up visual system is directly inherited from the industry standard of HUD, which is consistent with the minimum performance standard of HUD accuracy. Compared with the HUD, the airborne head-up vision system adds additional components of the vision system to...

AI Technical Summary

Problems solved by technology

At present, the methods in the industry to ensure the accuracy of the airborne head-up vision system are often accompanied by some trade-offs, such as increasing the cost of product processing and assembly accuracy, or sacrificing product interchangeability by directly calibrating the product during the target calibration process, etc.
