Provided are a device and a method for assisting in safe navigation 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 position and a moving direction of the moving body; an obstacle information acquisition unit that acquires obstacle information including a position and a movement direction for each of the plurality of obstacles; a collision risk value calculation unit that calculates a collision risk value on the basis of the moving body information and the obstacle information; a maximum collision risk obstacle selection unit that selects a maximum collision risk obstacle corresponding to the maximum collision risk value from among the obstacles; a congestion risk value calculation unit that calculates a congestion risk value indicating the degree of simultaneous approaching for one or more obstacles including/excluding the obstacle having the maximum collision risk; and a risk evaluation unit that determines, on the basis of the congestion risk value, that the vehicle travels along a route that is different from the planned route.
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辅助装置以及方法。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,获取包括移动体的位置和移动方向在内的移动体信息;障碍物信息获取部,针对多个障碍物的每一个获取包括位置和移动方向在内的障碍物信息;碰撞风险值计算部,基于移动体信息和障碍物信息计算碰撞风险值;最大碰撞风险障碍物选定部,在障碍物中选定与最大的碰撞风险值对应的最大碰撞风险障碍物;拥堵风险值计算部,针对包括/排除最大碰撞风险障碍物的一个或多个障碍物,计算表示同时接近的程度的拥堵风险值;以及风险评价部,基于拥堵风险值决定航行在与所述计划航路不同的避航路径。
