Document Type and Number:
WIPO Patent Application WO/2023/286825
Kind Code:
A1
Abstract:
Provided is a navigation assistance device with which it is possible to determine a navigation obstacle zone by taking into account a margin. This navigation assistance device allows for determination of a navigation obstacle zone based on the relationship between one vessel and another vessel. The navigation assistance device comprises: a margin extent acquisition unit that acquires a margin extent indicating the extent of a margin; and a computation unit that determines a margin position, which is a position away from the position of at least one of the bow or the stern of the other vessel by a distance determined according to the margin extent in a target occupied space set with respect to the position of the other vessel, that determines a collision course on the basis of a position determined according to the motion vector of the other vessel with respect to the margin position, and that calculates the navigation obstacle zone on the basis of the thus determined collision course.
