Disaster monitoring and early warning method for extra-high voltage dense power transmission channel

The invention discloses a disaster monitoring and early warning method for an extra-high voltage dense power transmission channel. The method comprises the following steps: S1, obtaining multi-source remote sensing image data of landforms, terrains, roads, buildings and power transmission channels in a certain area through a Beidou satellite and an interference radar; S2, unifying the multi-source image data to the same coordinate system for spatial registration; and S3, carrying out information fusion on the multi-source remote sensing image data after spatial registration, and constructing a three-dimensional visual model of the power transmission line in a certain region by applying AI image recognition, artificial intelligence and refined modeling technologies. S4, establishing and training a disaster early warning model according to the earth surface data and the historical disaster data; and S5, carrying out surface area deformation analysis and suspected disaster point identification.
