Blanking operation method and system of ship loader for bulk cargo wharf

The invention discloses a ship loader blanking operation method and system for a bulk cargo wharf. The method comprises the steps of obtaining initial ship point cloud data; establishing a three-dimensional coordinate system, and obtaining an initial frame cabin center line and a blanking planning point; continuously scanning the ship to be unloaded to obtain real-time ship point cloud data, and obtaining a current frame ship midline and a normal vector of a ship deck according to the real-time ship point cloud data; obtaining a real-time ship body deviation value according to the ship lock center line of the current frame and the cabin center line of the initial frame; obtaining a real-time ship body inclination angle according to the normal vector of the ship deck; the coordinates of the blanking planning point are corrected according to the real-time ship body deviation value and the real-time ship body inclination angle, the coordinates of the real-time blanking planning point are obtained, and the coordi
