Abstract:
To estimate specific marks related to a navigation of ships such as quays and jetties with high accuracy. The navigation supporting device (10) is provided with a candidate generating unit (30), a selecting unit (40), and a shape estimating unit (50). The candidate generating unit (30) generates a plurality of candidate line segments for constituting a target based on point cloud data including a plurality of point clouds obtained by detecting surroundings of a ship. Based on a positional relationship between the ship and the plurality of candidate line segments, the selecting unit (40) selects an estimated line segment constituting the target from the plurality of candidate line segments. Further, the shape estimating unit (50) estimates the shape of the target based on the selected estimated line segment.
