The application relates to a ship trajectory
reconstruction method and
system, which comprises the following steps: acquiring a ship trajectory, the ship trajectory comprising a plurality of track points arranged in
time sequence; identifying a stay point in the track points, and determining a stay boundary and a stay time at the stay point, the stay boundary comprising an
arrival time and a departure time at the stay point; and counting time interval statistical features between adjacent two track points outside the stay time, between the stay time boundary and adjacent track points thereof, to identify a missing section in the ship trajectory; reconstructing the missing section based on the type of the missing section by using a corresponding
reconstruction method to obtain reconstruction data, the type of the missing section comprising a first type of missing section or a second type of missing section, the first type of missing section being reconstructed by using a first
reconstruction method, and the second type of missing section being reconstructed by using a second reconstruction method; and filling the reconstruction data into a corresponding missing section of the ship trajectory to obtain a finally reconstructed ship trajectory.
