Marine operation helicopter pose measurement method and system based on binocular vision

The invention discloses an offshore operation helicopter pose measurement method and system based on binocular vision. The method comprises the steps that a rapid mooring device coordinate system and a deck coordinate system are established; calibrating internal and external parameters of the camera; the camera collects a current image of a helicopter tail wheel motion area in real time and transmits the current image to the data processing module; calculating position coordinates of a tail wheel rotating shaft in the helicopter in the coordinate system of the rapid mooring device; calculating the tangent vector of the tail wheel of the helicopter in the rapid mooring device coordinate system along the ship bow direction; calculating the direction vector of the axis of the helicopter fuselage in the rapid mooring device coordinate system along the ship bow direction; calculating a position coordinate of a helicopter mooring rod in the deck coordinate system, and a fuselage deflection angle and a tail wheel de
