Three-dimensional live-action twinning method and system based on position intelligence technology

The invention provides a three-dimensional live-action twinning method based on a position intelligence technology, and the method comprises the steps: constructing a Henning twinning body standard model of equipment for typical equipment in a target power grid; establishing a mapping relation between an equipment object and the digital twin standard model; according to the mapping relation, mapping of the equipment real object to the digital twin standard model is achieved; constructing a three-dimensional virtual scene of the digital Lie body standard model by taking a city as a basic geographic background, and displaying live-action information of a target power grid through the three-dimensional virtual scene; providing visual rendering styles of the digital twin standard model under different scales through a distribution network topological graph; and three-dimensional visualization of the distribution network frame is realized through the digital twinborn body standard model so as to reflect the operat
