摘要
提出了一种新的绝缘子图像提取算法,可用于直升机巡线时获取的航拍图像。介绍了对绝缘子图像特征的分析,说明了绝缘子图像的提取方法。算例结果表明:该算法能够从背景复杂的航拍图像中提取出玻璃绝缘子或陶瓷绝缘子的图像。
This paper proposes an algorithm based on maximum entropy and Hough transform in order to extract insulator image from aerial image of helicopter patrol.The method for analyzing insulator image features and extracting images are presented.Calculation results show that the proposed algorithm can extract both glass and porcelain insulator image from aerial image with complicated background.
