Geological disaster-based power transmission line digital twinborn modeling method and system

The invention discloses a power transmission line digital twin modeling method and system based on geological disasters, and relates to the technical field of power line modeling, and the method comprises the steps: carrying out the flight collection through employing an unmanned plane, and obtaining the image data of a power line region; processing the acquired image data to generate a three-dimensional scene, and correcting the three-dimensional scene in combination with geological and topographic maps; the method comprises the following steps of: acquiring an oblique picture by using an unmanned aerial vehicle five-splicing oblique camera, generating three-dimensional model data and true orthophoto data by control point information, and acquiring two-dimensional vector data with high current potential from the true orthophoto data; and integrating various data, and constructing a refined power line digital twinborn model. The method is of great significance to digital upgrading of the power line, the intel
