Multi-model collaborative ship unloading operation method and system

The invention discloses a multi-machine-type collaborative ship unloading operation method, and aims to enable a portal crane and a ship unloader to work collaboratively and improve the ship unloading efficiency. Meanwhile, the invention provides a multi-machine-type collaborative ship unloading operation system, and the technical scheme is that the multi-machine-type collaborative ship unloading operation method comprises the following steps that 1, a portal crane and a ship unloader move to a bulk cargo ship berth preset point, whole bulk cargo ships are scanned, and point cloud data are obtained; 2, splicing the point cloud data, and establishing a whole ship point cloud model; 3, according to the point cloud model of the whole ship, planning the positions of the portal crane and the ship unloader relative to the respective operation cabins, and enabling the portal crane and the ship unloader to move to the planned positions respectively; and 4, according to the positions of the portal crane and the ship u
