High Voltage Insulator String Automatic Location Method Based on Infrared Image
摘要
Abstract
Insulator string automatic location is an important premise of realizing the intelligent testing of the deteriorated insulator by infrared technology. Aiming at the characteristics of infrared image complex back-ground, this paper proposes an insulator string automatic location method based on gray threshold segmenta-tion and Hough transform. Firstly, the infrared image of insulator string is enhanced by gray level stretching based on Otsu threshold; the gray image open-operation is carried out to denoise the whole image; then gray Otsu threshold method is adopted to segment the image; after the binarization of the image, maximum con-nected region filtration method is carried to retrieve the region of insulator string; at last, Hough transform is used to do the image gradient correction ,achieving insulator string final automatic location. Experiment re-sults show that the proposed segmentation can retrieve the target fast and perfectly; the proposed location method can achieve insulator string location under complicated backgrounds automatically and accurately, and it lays a foundation for the intelligent testing of the deteriorated insulator by infrared technology.关键词
