Positioning method and positioning system under fully mechanized coal mining face hydraulic support scene

The invention provides a fully mechanized coal mining face hydraulic support scene positioning method and positioning system, and belongs to the technical field of positioning. The positioning method comprises the following steps: S1, base station data packing: obtaining positioning data of each base station based on a tag card, and obtaining a position set {Xt} with directions; s2, data normalization processing: converting a position set {Xt} with directions into a roadway value set {Rt}, and then removing singular values; s3, data fusion: data fusion is carried out on the roadway value set after the singular values are removed, a predicted value R't after data fusion is obtained, and the value is a positioning roadway value of the label card at the moment t; and S4, area discrimination: identifying the area where the current positioning card is located according to the predicted value R't. The method has the beneficial effect that the 30 cm high-precision positioning under the hydraulic support environment
