The icing-thickness detection of high-voltage transmission line based on machine vision

In order to detect the icing thickness of High-Voltage transmission lines, this paper proposes a new method based on machine vision. Firstly, the hardware device is calibrated to find the relationship between the distance from the observation point to the object and the geometric size of each pixel on the image. Then, it extracts the edge of the image, and the number of pixels is calculated. Finally, the paper also verifies the validity of the method by the simulation experiment, and realizes the automatic detection of the icing thickness, which improves the work efficiency and reduces the labour intensity of workers.
