NAVIGATION SUPPORT DEVICE FOR VESSEL

To provide a navigation support device for a vessel capable of performing the determination close to a sense of a ship operator regarding danger of collision between a first vessel and a second vessel.SOLUTION: A navigation support device for a vessel includes: a TCPA regarding a first vessel and a second vessel; an information acquisition unit 301 for acquiring an encounter angle between the first vessel and the second vessel; a weighing coefficient setting unit 303 for setting a first weighing coefficient corresponding to the TCPA on the basis of the acquired encounter angle and the TCPA; and a normalization unit 304 for normalizing the TCPA acquired using the first weighing coefficient and calculating a normalization value for determining collision danger between the first vessel and the second vessel.SELECTED DRAWING: Figure 8 【課題】第１船舶と第２船舶との衝突危険に関し、操船者の感覚に近い判定を可能とする船舶用航行支援装置を提供する。【解決手段】第１船舶及び第２船舶についてのＴＣＰＡと、第１船舶及び第２船舶間の出会い角とを取得する情報取得部３０１と、取得された出会い角及びＴＣＰＡに基づいて、該ＴＣＰＡに対応する第１重み係数を設定する重み係数設定部３０３と、第１重み係数を用いて取得されたＴＣＰＡを正規化し、第１船舶及び前記第２船舶の衝突危険を判定するための正規化値を算出する正規化部３０４とを備えた。【選択図】図８
