摘　　要：针对电缆区域多样且数量较多等原因导致各区域难以分割的问题,提出一种基于箱型图与折点阈值边界的电缆分割方法。设计一种HSV空间下的阈值边界分割方法;根据电缆结构特征对各区域进行初步分割,对分割结果进行统计,根据箱型图计算各通道的初始阈值边界;计算折点阈值边界并完成区域的精确分割。实验结果表明,该算法对于不同的电缆区域可以自适应计算该区域的色调中位数以及阈值边界,算法分割效果好,鲁棒性高。Aiming at the problem that the cable area is difficult to be separated due to the diversity and large number of cable areas,a cable segmentation method based on box-plot and turning point threshold boundary is proposed.A threshold boundary segmentation method under HSV space was designed.According to the structural characteristics of the cable,the regions were preliminarily segmented.The segmentation results were statistically analyzed,and the initial threshold boundary of each channel was calculated according to the box-plot.The threshold boundary of the turning point was calculated and the region was precisely segmented.The experimental results show that this algorithm can adaptively calculate the hue median and threshold boundary of the region for different cable regions,and it has good segmentation effect and high robustness.
