Abstract

Embodiments of the present invention provide a method for detecting power transmission towers based on synthetic aperture radar images, by processing high-resolution synthetic aperture radar (Synthetic Aperture Radar, SAR) images to obtain a region of interest (Region of Interest, ROI), and Calculate the semi-variance feature of the corresponding area, and use the neural network to detect the transmission tower. The present invention does not require that the image must be an expensive full-polarization SAR image, and for the same SAR image, especially when the outline of the high-voltage transmission tower on the image is not clear and there are many false targets, the present invention can detect More transmission tower targets, and the detection false alarm rate is lower than the existing technology.

Description

technical field [0001] The invention relates to the technical field of transmission line monitoring, in particular to a method for detecting transmission towers based on synthetic aperture radar images. Background technique [0002] With the rapid development of my country's social economy, the demand for electric energy continues to increase, which makes the scale of my country's power grid continue to expand. As an important part of the power grid, transmission lines are widely distributed in various regions, and the terrain, geology, and meteorological environment of the areas they pass are extremely complex. Events such as extreme weather and geological disasters will threaten the safety and stability of transmission line operation, and even cause large-scale power outages in the power grid, causing serious losses to the national economy and people's lives. Since the operation status of transmission lines and towers determines the stability and safety of the entire powe...
