The present invention addresses the problem of providing a sailing assistance device capable of displaying, with a small calculation load, a collision risk region that matches the sailing feeling of a sailing person. [Solution] A driving assistance device (1) is provided with a risk calculation unit (33) and a display data generation unit (41). A risk calculation unit (33) calculates the risk of the ship on the basis of the distance between the predicted position of the other ship and the correspondingly predicted position of the ship at a plurality of times in the future, taking into account the physical size of at least one of the ship and the other ship. A collision risk value for determining whether or not a collision risk region, which is a region in which a collision between a self ship and another ship is highly likely to occur in the future, is displayed, is calculated. On the basis of a determination using the collision risk value, a display data generation unit (41) generates display data for displaying the collision risk area at the predicted position of the other ship.
课题在于,提供能够以较小的计算负荷显示匹配驾船者的驾船感受的碰撞危险区域的驾船支援装置。解决手段在于,驾船支援装置(1)具备风险计算部(33)和显示数据生成部(41)。风险计算部(33)考虑自船及他船之中的至少一方的物理大小,基于未来的多个时刻的被预测的他船的位置与相对应地被预测的自船的位置之间的相隔距离,计算用于判断是否显示自船与他船的碰撞在未来发生的可能性高的区域即碰撞危险区域的碰撞风险值。显示数据生成部(41)基于使用碰撞风险值的判断,生成用于在被预测的他船的位置显示碰撞危险区域的显示数据。
