The Application of Improved RHT in High-voltage Transmission Lines Detection

The detection of high-voltage transmission lines was one of the important part of Smart Grid.The image was acquired by the industrial cameras set up on a high-voltage transmission line towers.The algorithm was proposed based on improved Randomized Hough Transform (RHT).According to the particularity of the collected images, image enhancement,filtering and edge detection preprocessing was needed before detection.And,cause of the linear characteristics of the high voltage transmission lines and angle characteristics,we used improved RHT combined with the angle to complete transmission line detection. Compared with traditional Hough Transform, the algorithm could save testing time,improve the detection accuracy, laid the foundation for real-time detection.Through processing pictures, it was well improved that the algorithm can detect the high-voltage transmission lines effectively.
