A Correction Method for the Motion Measurement of the Ship-Borne Mechanical Platform Based on Multi-Sensor Fusion

In order to perform multi-degree-of-freedom motion measurements of marine machinery, such as ship-borne mechanical platforms, in an absolute environment without a reference, measurement methods using acceleration sensors and tilt gyroscopes are typically employed. However, the influence wave forces on platforms can cause coupling between different degrees freedom, resulting significant disturbances that make efficient computation real-time analysis challenging. To address these challenges, correction method for platform based multi-sensor fusion is proposed by analyzing inclination angle sensor working principles sensor. this article, we first analyzed integral effect heave direction. Then, configuration four groups correct effect. Finally, optimal determined through Kalman filtering measured values estimated from sets. Experiments have proved average error corrected displacement signal 25.34 mm, which better than single At same time, use calculate roll pitch combine it with filtering. This filters out errors caused shaking instability more accurately estimate true platform. Therefore, enhance precision accuracy acquisition, providing valuable experimental data research engineering related fields.
