Multi-source AIS data completeness processing method based on ship messages

The invention relates to the technical field of multi-source AIS data fusion perfection processing, in particular to a ship message-based multi-source AIS data perfection processing method, which comprises the following steps of: receiving current AIS data subjected to pre-fusion processing; judging whether the current AIS data is a dynamic ship message or a static ship message according to the message ID in the current AIS data; when the message is determined to be a dynamic ship message, sequentially performing message time sequence adjustment processing, message field verification processing and position verification processing on the dynamic ship message to obtain output AIS data; and when the ship message is determined to be a static ship message, sequentially performing message field verification processing and information difference compensation processing on the static ship message to obtain output AIS data. By adopting the method, the accuracy, rationality and integrity of AIS data output can be impr
