摘要： 在基于图像处理分割机场跑道异物(FOD)的方法中,基于深度学习的方法不能准确感知未经训练的异物。对此,提出基于双通道麻雀改进大津法(OTSU)的分割方法(DS-OTSU)来分割感知异物。该分割方法将麻雀搜索算法与OTSU相结合,在麻雀搜索算法中加入佳点集优化初始种群,同时在双通道中分别加入正反两个方向的扰动,从而改变麻雀搜索算法目标函数的计算方法,通过加入双重动态的萤火虫扰动改变种群更新方式,将双通道的运行结果进行对比融合,将原本只能单阈值分割图像的OTSU优化为可以分割阈值段的方法,滤除图像背景部分,最终得到FOD的分割结果。实验分析表明,所提方法在分割精度和收敛速度上均优于其他方法。

Abstract: In the method of segmenting foreign object debris(FOD) on airport runways based on image processing,the segmentation based on deep learning cannot accurately perceive untrained FOD.Therefore,a segmentation method is proposed in this paper,based on the improved Otsu method of dual-channel sparrow(DS-OTSU).In this segmentation method,the sparrow search algorithm is combined with OTSU,the optimal point set is added to the sparrow search algorithm to optimize the initial population,and the perturbations in the positive and negative directions are added to the dual channels to change the calculation method of the objective function of the sparrow search algorithm.Experimental analysis shows that the detection accuracy and convergence speed of the proposed method are superior to those of other methods.

Key words: Threshold segmentation, OTSU, Foreign object debris on airport runways, Sparrow search algorithm, Firefly distur-bances
