| 中文摘要: |
| 提出包覆裸导线的硅橡胶绝缘套管（简称硅橡胶绝缘套管）的绝缘效果图像特征检测方法。首先采用双边-拉普拉斯算法对硅橡胶绝缘套管的图像展开滤波和增强处理；其次建立灰度行程矩阵，以相关系数选取硅橡胶绝缘套管的老化特征；然后基于时域反射技术，通过检测导线中脉冲波的传播特性变化实现硅橡胶绝缘套管的绝缘效果检测。试验结果表明，本方法的图像采集质量高、老化检测精度高、绝缘检测效果好。 |

| An image feature detection method for the insulating effect of the silicone rubber insulation sleeve covering bare wire（referred to as silicone rubber insulation sleeve） was proposed.Firstly，the bilateral-Laplace algorithm was used to filter and enhance the image of the silicone rubber insulation sleeve.Secondly，a grayscale travel matrix was established，and the aging characteristics of the silicone rubber insulation sleeve were selected based on correlation coefficients.Then，based on time domain reflection technology，the insulating effect detection of the silicone rubber insulation sleeve was implemented by detecting changes in the propagation characteristics of pulse waves in the wire.The experimental results showed that the method had high image acquisition quality，high aging detection accuracy and good insulating detection effect. |
