Abstract:

In maritime search and rescue, customs anti-smuggling and other scenarios, it is often necessary to forecast vessels' trajectory. In order to improve the accuracy and efficiency of the prediction, a method for vessel trajectory prediction based on recurrent neural network is proposed. The method includes data preprocessing and neural network prediction. In data preprocessing, a data preprocessing method based on symmetric segmented-path distance is designed to eliminate the influence of a large number of redundant data and noise. In the prediction of neural network, the model of recurrent neural network with gated recurrent unit as the core is constructed to realize the accurate and efficient prediction of vessels'position information. Comparative experiment is made through a large number of data from the automatic identification system, and experiment results prove that the proposed method is practical and effective.

Key words: trajectory prediction, automatic identification system, symmetrized segment-path distance, gated recurrent unit
