To estimate a specific target at high accuracy regarding navigation of a vessel on such as a barge or a pier.SOLUTION: A navigation support device 10 includes: a candidate generation unit 30, a selection unit 40, and a configuration estimation unit 50. The candidate generation unit 30 generates a plurality of candidate line segments for composing an estimation object target based on point group data composed of a plurality of point groups obtained by detecting periphery of the vessel. The selection unit 40 selects a plurality of estimation material segments composing the estimation target object based on physical relationship between the vessel and the plurality of candidate segments. The configuration estimation unit 50 estimates configuration of the estimation object target based on the selected plurality of estimation material segments.SELECTED DRAWING: Figure 1

    【課題】岸壁や桟橋のような船舶の航行に関する特定物標を高精度に推定する。【解決手段】航行支援装置10は、候補生成部30、選択部40、および、形状推定部50を備える。候補生成部30は、船舶の周囲を検知して得られた複数の点群からなる点群データに基づいて、推定対象物標を構成するための複数の候補線分を生成する。選択部40は、船舶と複数の候補線分との位置関係に基づいて、推定対象物標を構成する複数の推定素材線分を複数の候補線分から選択する。形状推定部50は、選択した複数の推定素材線分に基づいて、推定対象物標の形状を推定する。【選択図】 図1
