| 摘 要： | 针对高铁接触网绝缘子破损的不良状态图像检测问题,提出一种利用曲波变换的绝缘子不良状态定位检测方法。先通过Radon变换实现绝缘子角度的确定,接着运用曲波变换对系数矩阵进行统计处理,最后实现绝缘子的角度调整、定位和破损情况判断。该方法能够精确定位绝缘子,并给出不良状态的判断,可以为工程应用提供技术参考。 |

| Abstract: | Aiming to the insulators of the High-speed railway breakages,this paper presents a method based on curvelet transform to solve it.First,the insulators’ angle is determined by Radon transform.Then,the paper makes use of curvelet transform to deal with the coefficient matrix.Last,the insulators’ angle adjustment,location and breakages are correctly found.The fact proves that this method can accurate locate and judge the adverse state of insulators.It can offer the technical reference for engineering application. |
| Keywords: | insulators curvelet transform radon transform adverse state detection |
