Substation scene fusion three-dimensional reconstruction method and system based on digital twinning

The invention provides a substation scene fusion three-dimensional reconstruction method and system based on digital twinning, and relates to the technical field of digital twinning three-dimensional reconstruction, and the method comprises the steps: obtaining a multi-view live-action aerial image of a target substation, and carrying out the preprocessing; extracting scene features in the multi-view live-action aerial image, and constructing an initial scene three-dimensional model; taking an image containing the physical equipment as a candidate image, inputting the candidate image into the image position and attitude prediction model, and outputting a position and attitude result; determining a space range of the entity equipment according to a position posture result, performing superposition fusion on the entity equipment and the scene three-dimensional model based on projection transformation, and constructing a final visual substation scene fusion three-dimensional model; dynamic changes in the transfo
