Ship route extraction method and system based on ship behavior mode

The invention discloses a ship behavior pattern-based route extraction method and system, and the method comprises the steps: carrying out the data classification and screening of AIS data through employing a ship behavior pattern as a classification standard, and obtaining the AIS data corresponding to a berthing mode and a turning mode; aIS data corresponding to a parking mode is processed through a DBSCAN algorithm of self-optimization parameters, a parking area is determined, AIS data corresponding to a turning mode is processed through a sliding pane technology, and a waypoint is determined, so that the parking area and the waypoint related to the determined route are obtained, screening of the AIS data is achieved, and the screening efficiency of the AIS data is improved. The subsequent data processing amount is reduced; furthermore, data processing is performed on the waypoints and the parking areas by constructing a rasterization route extraction model based on semantic analysis, so that the target ro
