摘要
提出一种基于蜂巢模型标记的飞机蒙皮小型损伤定位方法。利用CCD相机对损伤位置进行拍摄,对图像进行亚像素级处理,得到相应的坐标。根据调和共轭原理和交比不变性可求得实际位置,实现准确定位。以实际位置为主基点进行基点传递,利用蜂巢模型的无限性与无缝隙外扩性,实现蒙皮表面其他基点与主基点的特征对比与匹配,进而完成对飞机蒙皮破损的精确检测。对比实验的结果表明:本文方法具有精度高、耗时少等特点,能有效地实现飞机蒙皮的破损检测定位。
Abstract
A location method for minor damages of aircraft skins based on a marked honeycomb model is proposed. A CCD camera is used to capture the damage location, and the image is processed at sub-pixel level to obtain its coordinates. According to the principles of harmonic conjugation and the invariance of cross-ratios, the actual position of the damage can be determined to achieve accurate positioning. Then, based on this, the base point is transmitted and the infinite and seamless extensibility of the honeycomb model are used to compare and match of main base points and other base points on the surface of the aircraft skin so as to achieve accurate detection of the aircraft skin damage. The comparative experimental results show that the proposed method has high accuracy and less time consuming, and can effectively realize damage detection and location for aircraft skins.
