To provide a shore arrival assisting device for a ship capable of accurately acquiring a location of the ship.SOLUTION: A shore arrival assisting device for a ship comprises a location and azimuth information acquisition section, a LIDAR, a map generation and update section, a high place point acquisition section, and a location and azimuth estimation section. The LIDAR acquires point group data 40 indicating an environment around a ship 2 in a three-dimensional manner. The map generation and update section generates a map 41 around the ship 2 on the basis of the point group data 40. The high place point acquisition section acquires high place points equal to or higher than a predetermined height in the point group data 40. The location and azimuth estimation section estimates a location and an azimuth of the ship 2 by matching locations of the high place points obtained by the high place point acquisition section and locations of high place points in the map 41. The map generation and update section updates the map 41 by disposing the point group data 40 on the map 41 with a location and an azimuth of the ship 2 estimated by the location and azimuth estimation section, defined as a reference.SELECTED DRAWING: Figure 2

    【課題】船舶の位置を精度良く取得することができる船舶の着岸支援装置を提供する。【解決手段】船舶の着岸支援装置は、位置方位情報取得部と、LIDARと、地図生成更新部と、高所点取得部と、位置方位推定部と、を備える。LIDARは、船舶2の周辺の環境を3次元的に示す点群データ40を取得する。地図生成更新部は、点群データ40に基づいて船舶2の周辺の地図41を生成する。高所点取得部は、点群データ40のうち、所定高さ以上の高所点を取得する。位置方位推定部は、高所点取得部により得られた高所点の位置と、地図41における高所点の位置と、のマッチングによって、船舶2の位置及び方位を推定する。地図生成更新部は、位置方位推定部により推定された船舶2の位置及び方位を基準として点群データ40を地図41に配置することで、当該地図41を更新する。【選択図】図2
