The invention belongs to the technical field of track monitoring, and provides a digital twinning state monitoring method for a maglev line track fusing air-track-ground multi-dimensional information, and the method comprises the steps: building a three-dimensional model of a segmented line track based on the aerial photography information of an unmanned plane and a BIM technology; acquiring surface feature data of the selected segmented line track by using a section scanner, and reconstructing a three-dimensional model of the selected segmented line track by combining attitude and position information of an inertial navigation system; and finally splicing the reconstructed three-dimensional model and the non-reconstructed segmented line track model to obtain a line track geometric model, improving the modeling precision, constructing a database based on the qualified holographic state data, and constructing a behavior and rule model of the magnetic levitation line track digital base in combination with the constructed geometric model. Information fusion is carried out on isomorphic and heterogeneous holographic state data by using a Kalman filtering fusion algorithm, and diversified intelligent monitoring of the magnetic levitation line track is realized.
