Abstract
This application discloses a method, device, medium, and product for short-to-medium-term ship motion prediction based on a spatiotemporal fusion Informer model, relating to the field of ship motion prediction. The method includes: acquiring short-to-medium-term ship motion parameters, environmental parameters, and wave spectrum parameters to generate time-series data; performing spatial and positional encoding on the time-series data, and obtaining spatiotemporal fusion features based on the spatial and positional encoding results; constructing a spatiotemporal fusion Informer model by introducing a multi-head ProbSparse attention layer and a Distilling layer; and obtaining ship motion prediction results based on the spatiotemporal fusion features using the spatiotemporal fusion Informer model. This application can improve the efficiency and accuracy of short-to-medium-term ship motion prediction, providing key technical support for intelligent maritime aviation operation systems.
