摘要
针对绝缘子图像,根据其颜色特性,得出HSI颜色空间满足图像分割的要求;并对色调分量所具有的特点,提出了色调直方图折叠法,可以有效减少对背景的误分割。分割方法上选取最大类间方差法的阈值分割。对于单个色调或饱和度分量图像分割结果中的不足,提出将两者的分割结果求交集,经形态学处理后得到的分割结果,为后续的绝缘子故障判断提供了依据。
Based on color characteristics of insulator images,we concluded that the HIS color space satisfies requirements of image segmentation.In addition,we proposed the hue bar-graph folding method based on characteristics of the hue component.The method reduces mis-segmentation of the background.We selected Otsu＇s thresholding method for segmentation.Against the flawed image segmentation results of single components,H or S,we proposed to find the intersection of the two segmentation results.The segmentation result obtained through morphological processing provides the basis for follow-up determination of insulator faults.
