Provided are a route planning device and method for sailing safely while avoiding collision between a moving body such as a ship and an obstacle such as another ship. The present invention is provided with: a planned route acquisition unit that acquires planned route information indicating a planned route of a moving body; a moving body information acquisition unit that acquires moving body information including a moving body position and a moving direction; an obstacle information acquisition unit that acquires obstacle information including a position and a movement direction for obstacles in the vicinity of the moving body; a voyage avoidance path acquisition unit for acquiring voyage avoidance path information different from the planned route by using the voyage avoidance starting point as a starting point; a collision risk value calculation unit that calculates a collision risk value between the moving body and each obstacle on the basis of the moving body information and the obstacle information; the maximum collision risk value comparison part is used for calculating and comparing maximum collision risk values for the planned route and the voyage avoiding path respectively; and a route change signal output unit which, when the maximum collision risk value of the voyage avoidance path is lower than the planned route, instructs a route change signal to change the voyage avoidance path.
提供避免船舶等移动体与其他船等障碍物碰撞并安全航行的航路计划装置以及方法。具有:计划航路获取部,获取表示移动体的计划航路的计划航路信息;移动体信息获取部,获取包括移动体位置和移动方向的移动体信息;障碍物信息获取部,针对移动体周边的障碍物,获取包括位置和移动方向的障碍物信息;避航路径获取部,以避航开始点为起点,获取与计划航路不同的避航路径信息;碰撞风险值计算部,基于移动体信息和障碍物信息,计算移动体与各障碍物的碰撞风险值;最大碰撞风险值比较部,分别针对计划航路和避航路径计算最大碰撞风险值并比较;航路变更信号输出部,避航路径的最大碰撞风险值低于计划航路时,指示向避航路径的航路变更的航路变更信号。
