AI Technical Summary
Existing shipborne wave compensation technologies lack a unified planning framework, have insufficient sensing accuracy and robustness, and are unable to meet the real-time closed-loop control requirements under complex sea conditions.
A visual-inertial fusion nine-degree-of-freedom wave compensation method is adopted. Through visual-inertial perception, unified kinematic modeling, end-point compensation target transformation and multi-task planning, the method realizes real-time perception of hull disturbance, generation of compensation targets and multi-degree-of-freedom collaborative allocation.
It improves the compensation accuracy, real-time performance, and engineering applicability of the wave compensation system, enhances the position and attitude perception accuracy and robustness, and improves the docking stability and operational safety under complex sea conditions.
