- Abstract:
-
The automatic identification system (AIS) data consists of a large amount of information associated with shipping behavior. A wide range of applications in maritime supervision and ship surveys can be made use of by extracting useful ship routes from AIS data. The gate recurrent unit auto-encoder (GRU-AE) is the foundation of a method for ship route extraction that is suggested. First, the GRU encoder is employed to encode the original trajectory data into deep feature information in a unified form; then, deep feature information is clustered using the DBSCAN algorithm; and finally, the deep feature cluster center is inverted through the decoder to produce the corresponding ship route, to achieve the mining of the ship trajectory pattern in the massive AIS data. Taking the Port of Boston as an example, more than 100,000 AIS ship navigation data in one year are examined. Experiments reveal that this technique can cluster and extract route data of various lengths and can support the research of ship trajectory abnormality identification, path planning, position prediction, etc., revealing good application adaptability.
