Fully mechanized coal mining face alignment method and device

The invention discloses a fully mechanized coal mining face straightening method and device, and the method comprises the steps: scanning a whole fully mechanized coal mining face through a collection device, and obtaining a working face change curve of the fully mechanized coal mining face; projecting the working face change curve to a two-dimensional plane to obtain a straightness curve of the fully mechanized working face in the propelling direction of the hydraulic support; determining an alignment reference straight line according to the straightness curve; and straightening the fully mechanized coal mining face according to the straightness curve and the straightening reference curve. According to the method, the straightness curve of the whole fully mechanized coal mining face can be directly extracted, the fully mechanized coal mining face deviating from the alignment reference curve is automatically adjusted and corrected, dynamic monitoring of the straightness of the working face and timely and accu
