摘要:

针对自主空中加油任务中加油锥套检测鲁棒性不足以及相对定位精度不高问题,提出一种基于近红外视觉的加油锥套检测与定位方法,在加油锥套上安装8个近红外发光二极管作为特征点,在受油机搭载配置有近红外滤光片的相机作为视觉系统。首先,对捕获到的加油锥套图像进行预处理,提取连通区域;其次,提出形状先验驱动的邻域搜索方法,结合深度学习方法对锥套位置进行跟踪预测与锥套椭圆特征拟合;最后,基于透视n点算法解算相对位姿,并进行融合滤波处理。实验结果表明,本文提出方法具有较高的检测成功率、效率与相对定位精度,在实际空中加油任务中具备良好的应用前景。

Abstract:

To address the issues of insufficient robustness in refueling drogue detection and low relative positioning accuracy in autonomous aerial refueling missions, a near-infrared vision-based method for refueling drogue detection and localization is proposed. Eight near-infrared light emitting diodes are installed on the refueling drogue as feature points, while a camera equipped with a near-infrared filter is deployed on the receiver aircraft as the vision system. Firstly, the captured images of the refueling drogue are preprocessed to extract connected regions. Secondly, a shape prior-driven neighborhood search method is proposed, integrating deep learning approaches for drogue position tracking prediction and elliptical feature fitting. Finally, the relative pose is calculated using the perspective-n-point algorithm, followed by fusion filtering processing. Experimental results demonstrate that the proposed method achieves high detection success rate, efficiency, and relative positioning accuracy, showing promising application prospects in practical aerial refueling missions.

Key words: autonomous aerial refueling, visual positioning, near-infrared, refueling drogue detection, ellipse fitting
