The invention discloses a ship trajectory prediction method and system, computing equipment and a storage medium. The ship trajectory prediction method comprises the following steps: acquiring ship trajectory information within a preset time based on AIS data to generate a training data set and a prediction data set of a ship trajectory; constructing a trajectory prediction model of a bidirectional gating recurrent neural network based on an efficient attention mechanism, and training the trajectory prediction model through the training data set; and inputting the prediction data set into a pre-trained trajectory prediction model to obtain ship trajectory prediction information. According to the method, after ship trajectory information is input through the trajectory prediction model of the pre-constructed and trained bidirectional gating recurrent neural network, a more accurate ship trajectory prediction result can be output, and the real-time performance is higher.
