Calculation of Unbalanced Tension of Transmission Line by Image Recognition Method of Insulator Deflection Angle

摘要

With the development of the transmission line, it is more and more important to analyze the unbalanced tension of the tower. The non-contact method of measuring the insulator deflection angle uses image processing techniques, and the experimental results show that this method has better recognition speed and accuracy. First, we capture insulator image by using a camera fixed on the tower; then use image filtering, image thinning techniques for image pre-processing. Finally, we extract the central axis of insulator using Hough transformation, get the insulator deflection angle and analyze the unbalanced tension. It can be worked out by the corresponding computer program.
