摘要： A navigation supporting display apparatus makes it easy for an operator of ship to navigate with a safe passing distance between own ship and a target by indicating an exact danger area between own ship and the target ship. The apparatus has a collision point calculator which calculates a possible collision point of each of the vertexes of a polygonal safe passing region set around own ship, and the target ship, from a relative position of the target ship, a velocity vector of the target ship and a velocity of own ship. The apparatus has an own-ship-mapping-position calculator which calculates a position at which own ship would be located when each of the vertexes places on the collision point, and defines the position as a own-ship-mapping-position. The apparatus further has a danger area calculator which determines lines joining own-ship-mapping-positions corresponding to the collision points with each other to define a danger area. The relation between connected own-ship-mapping-positions and the own-ship-mapping-positions are output to a display device, and the display device displays the area defined by the lines joining own-ship-mapping-positions as a danger area together with the position and the vector of own ship and the position of the target ship.
摘要翻译：导航辅助显示装置通过指示本船和目标船舶之间的确切危险区域，使船舶操作者能够轻松地以本船和目标之间的安全距离进行导航。该装置具有碰撞点计算器，该目标船舶的目标船舶的目标船舶的相对位置计算目标船舶的速度矢量，其中，所述碰撞点计算器计算在其船舶周围设置的多边形安全通过区域的每个顶点的可能碰撞点，和自己的船的速度。该装置具有自身映射位置计算器，当每个顶点放置在碰撞点上时，其计算自己的船将位于该位置的位置，并将该位置定义为自身船舶映射位置。该装置还具有危险区域计算器，该危险区域计算器确定将与碰撞点相对应的自身船舶映射位置彼此相关联的线，以定义危险区域。将连接的自身映射位置与自身映射位置之间的关系输出到显示装置，并且显示装置将由加入自身映射位置的线定义的区域显示为危险区域连同自己的船的位置和载体以及目标船的位置。
