一种基于聚类分析的输电线路覆冰检测方法和系统
摘要：
1、一种基于聚类分析的输电线路覆冰检测方法，其特征在于包括下列步骤：（1）从视频监控终端或视频录像中提取相邻帧图像；（2）对提取相邻帧图像进行图像的预处理；（3）利用基于聚类分析理论，对输电线路图像进行图像分割；（4）与无覆冰输电线路进行对比，判断输电线路是否覆冰；（5）根据输电线路在图像中的特征，采用连通区域标识来定位输电线路的位置。本发明从视频监控终端或视频录像中提取相邻帧图像，然后对提取相邻帧图像进行图像的预处理，利用基于聚类分析理论，对输电线路图像进行图像分割，根据输电线路在图像中的特征，采用连通区域标识来定位输电线路的位置，最后与无覆冰输电线路进行对比，判断输电线路是否覆冰。该方法无论从检测时间还是检测效果上都取得了较好的结果，能满足实际应用需要。
摘要（英）：

The invention provides a method for detecting icing of a transmission line based on clustering analysis. The method is characterized by comprising the steps of (1) extracting adjacent frame images from a video monitoring terminal or a video record; (2) preprocessing the extracted adjacent frame images; (3) segmenting a transmission line image based on the clustering analysis theory; (4) comparing with the non-icing transmission line to determine whether the transmission line suffers from icing; (5) locating the position of the transmission line through a communication area mark according to the characteristics of the transmission line in the image. According to the method, the adjacent frame images are extracted from the video monitoring terminal or the video record and then are preprocessed, the transmission line image is segmented based on the clustering analysis theory, the location of the transmission line is located through communication area mark according to the characteristic of the transmission line in the image, and finally the comparison is performed with the non-icing transmission line so as to determine whether the transmission line suffers from icing. With the adoption of the method, both the detection time and detection effect are obvious, and the actual application demand can be met.
