Method for monitoring underway ship in real time based on AIS and VTS information integration

The invention provides a method for monitoring an underway ship in real time based on AIS and VTS information integration. The method comprises the steps of collecting signals; acquiring AIS static information, AIS dynamic information, information related to the voyage number and information about the security of a target ship through an AIS; detecting VTS dynamic information of the target ship through a VTS, and reflecting information about the size and the shape of the target by using VTS radar target echoes; building a D-S evidence theory identification framework through analyzing the difference between the AIS dynamic information and the VTS dynamic information acquired by the AIS and the VTS radar respectively; and constructing a focal element confidence function based on a Kalman prediction algorithm, carrying out evidence synthesis within the D-S evidence theory identification framework, and judging monitoring results. The method provided by the invention is based on the two existing real-time monitoring modes for ships, utilizes the D-S evidence theory identification framework, and constructs the focal element confidence function based on the Kalman prediction algorithm so as to achieve more accurate monitoring results.
