Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line inspection, and in particular to a method for enhancing ice and snow coverage content of an image of a power facility. Background Art

[0002] When transmission lines pass through high-altitude, high-humidity, and low-temperature mountainous areas in winter, overhead wires are easily covered with ice and snow. In severe cases, the mechanical and electrical performance of the transmission lines may deteriorate sharply, causing very serious accidents such as power line tripping and tower collapse. Therefore, it is necessary to identify and discover the ice and snow coverage in power facilities. Due to the huge amount of power facility image acquisition, the color and background of the transmission lines in winter are relatively simple, so the patrol personnel are easily tired when inspecting the power facility images and thus miss the ice and snow coverage. Therefore, the enhanced expression of the ice and snow coverage content of the power facility image makes the ice and snow content more obvious, which is very important for the ice and snow coverage inspection of transmission lines.

[0003] At present, the main methods used to enhance the snow and ice content of power facility images include: 1) Using edge detection methods such as the Candy operator to draw the edge conditions in the image. This method is relatively easy to calculate, but under some weather conditions, power transmission equipment is prone to produce rime ice forms, and the boundaries of these forms will be similar to the image background (such as a mountain covered with stones), which will make the new boundaries more chaotic and reduce the recognition effect. 2) Using texture calculation formulas to identify based on a certain threshold. A typical feature of this method is to lock the results of specific distances, positions, and lighting, so that the results of experiments and papers with ideal conditions for this type of method are better, but in practical work, the conditions of cameras and drone lenses for power transmission equipment are often more variable, and texture efficiency is often extremely low. 3) Introducing artificial intelligence algorithms, such as convolutional neural networks and U-Net neural networks for deep recognition. This type of recognition relies on samples, and ice cover is often more common in some areas and less common in others. This makes it very easy for these neural networks to overfit to specific areas or morphological directions, resulting in a method that works well in one area being unable to be used in other areas. At the same time, deep intelligent methods often require more computing power and network data to implement, which will become a major obstacle to the edge deployment of algorithms and implementation in remote areas. In actual work, the implementation is often costly and has a low return rate.

[0004] Therefore, it is necessary to propose a simple and easy enhancement method specifically for the ice and snow cover features of power facilities, which can directly identify possible ice and snow features in an image and enhance their expression. Summary of the invention
