Problems solved by technology

However, because the aircraft skin is exposed to the air for a long time, it is a structure that is extremely prone to damage in the aircraft structure. In the history of aviation, aircraft accidents caused by damage to the aircraft skin are not uncommon.
Due to the harsh operating environment of the aircraft, in addition to the fatigue damage caused by normal flight, there are also structural corrosion caused by environmental factors. , there are certain hidden dangers to flight safety

Abstract

A small damage location method for aircraft skin based on honeycomb model. It includes establishing a small damage location system for aircraft skin; calibrating the camera; arranging honeycomb model marking points on the damaged part of the aircraft skin surface; using the camera to shoot the damaged part; The pixel edge of the marked point; extract the hexagonal boundary point from the pixel edge; calculate the line passing through the center of the marked point and the intersection coordinate of the line according to the hexagonal boundary point; calculate the intersection point coordinate of the marked point according to the intersection point coordinate of the marked point Steps such as the actual center location. The invention can realize feature comparison and matching between marking points on the surface of the aircraft skin, and further realize accurate detection of damaged parts of the aircraft skin. Its significance is to use the infinite and seamless expansion of the circular regular hexagonal honeycomb model for positioning design, so as to achieve high matching efficiency and high detection accuracy for aircraft skin damage detection.

Description

technical field [0001] The invention belongs to the technical field of visual calibration measurement, in particular to a honeycomb model-based small-scale damage location method for aircraft skin. Background technique [0002] The aircraft skin is a surrounding structure that surrounds the fuselage frame. It is fixed on the frame with adhesives, rivets or screws. In addition to forming and maintaining the starting shape of the aircraft, the aircraft skin also needs to bear local aerodynamic forces. However, because the aircraft skin is exposed to the air for a long time, it is a structure that is extremely prone to damage in the aircraft structure. In the history of aviation, aircraft accidents caused by damage to the aircraft skin are not uncommon. Due to the harsh operating environment of the aircraft, in addition to the fatigue damage caused by normal flight, there are also structural corrosion caused by environmental factors. , there are certain hidden dangers to fligh...
