The method mainly comprises the following steps: S1, acquiring to-be-processed three-degree-of-freedom data of a ship motion attitude, and preprocessing the data, which mainly comprises the following steps: sorting and acquiring the data, intercepting the data size, and performing normalization processing; s2, the best automatic optimization method is provided by using the advantages of a Harris Hawks Optimizer (HHO) and a Sine Cosine Algorithm (SCA), and the best automatic optimization method mainly comprises the following steps: designing a cross parallel optimization method framework, and initializing parameters of the optimization algorithm; s3, performing automatic optimization on parameters of the GRU neural network by adopting an SCA-HHO optimization algorithm, and fully developing the processing capability of the neural network, which mainly comprises the following steps: initializing a GRU network structure, and searching optimal parameters through an HHO-SCA optimization algorithm framework; and S4, assigning an optimal parameter corresponding to the obtained optimal fitness value to the GRU network, and predicting three-degree-of-freedom data of the ship after training. The SCA-HHO-GRU model framework provided by the invention can be used for solving the problems of low precision and large error during ship attitude prediction. By adopting the model provided by the invention, the motion attitude of the ship can be accurately predicted, and the normal take-off and landing of a shipboard aircraft and the safety of workers on the ship can be guaranteed.
