Problems solved by technology

[0003] However, because the pictures of high-voltage transmission lines are collected by remote monitoring, due to the influence of natural factors, the contrast of the actual pictures collected is not high. The gray value of the transmission line is similar to that of the sky. The influence of external noise will reduce the quality of the picture, which will inevitably increase the difficulty of wire detection

Embodiment 1

[0080] Embodiment 1: The present invention provides a power grid transmission line detection method based on image processing fusion network weights, such as figure 1 shown, including the following steps:

[0081] 1) Read in the images of the power grid transmission line generated during the inspection process of intelligent equipment such as helicopters, drones, robots, and fixed cameras;

[0082] 2) Grayscale processing of the input image, converting the collected 24-bit true color image into an 8-bit grayscale image to obtain a grayscale image;

Abstract

The invention discloses a power grid transmission line detection method and device based on image processing and fusion network weights. Transform a series of image processing methods; use Canny operator edge detection on the processed image; set a region of interest (ROI) in the image; classify the pixels in the ROI; use the deep network model to calculate the distribution map of the power grid transmission line in the picture . The grid transmission line distribution is fused with the classified pixel points. The transmission line is fitted according to the pixel points obtained by fusion, and the fitting result is displayed in the figure. At the same time, the equation of the output line and the number of high-voltage lines can be detected, and the high-voltage line can be detected with certain accuracy. At the same time, it can exclude roads, towers, The interference of backgrounds such as the sky and clouds, and the ability to identify crossed high-voltage lines, and to handle edge detection breakpoints, has certain robustness and practicability.

Description

technical field [0001] The invention relates to a power grid transmission line detection method, in particular to a power grid transmission line detection method and device based on image processing fusion network weights, and belongs to the technical field of image processing. Background technique [0002] With the development of image processing technology in the industrial field and the vigorous promotion of smart grids, remote monitoring has been gradually applied to smart grids. For high-voltage transmission lines in remote mountainous areas or areas with harsh conditions, using machines instead of manual inspections not only reduces inspection costs and management costs, but also reduces the work intensity of workers during inspections and reduces the risk of outdoor operations. [0003] However, because the pictures of high-voltage transmission lines are collected by remote monitoring, the contrast of the actual pictures collected is not high due to the influence of n...
