A controller (13) of an information processing device (1) functions as an acquisition means, an extraction means, and a straight line calculation means. The acquisition means acquires dot matrix data generated by a lidar (3) provided in a target ship, the dot matrix data being a set of data specified by a group of horizontal numbers that are indexes indicating lateral positions and vertical numbers that are indexes indicating vertical positions. The extraction unit extracts, for each horizontal number, data indicating a point to be measured at a docking location, data indicating a nearest point closest to a target ship for each vertical line from the data indicating the point to be measured at the docking location. A straight line calculation means calculates a shore side straight line (Ls), which is a straight line along the shore site, on the basis of a neighboring point set, which is a set of data representing the nearest neighboring points.
信息处理装置(1)的控制器(13)作为取得单元、提取单元及直线算出单元发挥功能。取得单元取得设置于对象船舶的激光雷达(3)生成的点阵数据,该点阵数据是通过表示横向的位置的索引即水平编号及表示纵向的位置的索引即垂直编号的组而确定的数据的集合。提取单元从表示靠岸场所的被计测点的数据针对每个水平编号、即针对每个纵线而提取表示与对象船舶最近的最邻近点的数据。并且,直线算出单元基于表示最邻近点的数据的集合即邻近点集合而算出沿着靠岸场所的直线即靠岸侧面直线(Ls)。
