Title:
NAVIGATION ASSISTANCE DEVICE AND NAVIGATION ASSISTANCE METHOD
Document Type and Number:
WIPO Patent Application WO/2024/053525
Kind Code:
A1
Abstract:
[Problem] To highly accurately estimate information indicating a ship state until docking. [Solution] This navigation assistance device comprises a host ship state detection sensor, a quay wall information detection unit, a motion state calculation unit, a distance calculation unit, and an arrival state calculation unit. The host ship state detection sensor detects a host ship location, a host ship velocity, and a bow heading. The quay wall information detection unit detects a quay wall line of the quay wall where the host ship is docking. The motion state calculation unit calculates the velocity in the direction of the quay wall on the basis of the host ship velocity, the bow heading, and the line of the quay wall. The distance calculation unit calculates the distance between the host ship and the quay wall on the basis of the host ship location and the quay wall. The arrival state calculation unit calculates an arrival state including at least one among a quay wall arrival prediction time of the host ship, a prediction velocity at the time when the host ship arrives at the quay wall, and a deflection angle at the time when the host ship arrives at the quay wall on the basis of the velocity in the direction of the quay wall and the distance between the host ship and the quay wall line.
