The application provides a kind of self-interference continuous elimination method for the cooperative exploration of multiple unmanned ships in unknown areas, belonging to the technical field of autonomous exploration, autonomous positioning and map construction of multiple unmanned ships. To solve the self-interference problem that occurs when multiple unmanned ships cooperatively explore unknown areas, a coordinate relationship established by SLAM and multiple unmanned ship map fusion is used in combination with the iterative closest point registration algorithm to propose a laser radar point cloud method for continuously processing dynamic obstacles, which eliminates the self-interference of multiple unmanned ships in the cooperative exploration of unknown areas.
