The invention discloses a ship yaw early warning method and system based on a laser radar, and the method comprises the steps: obtaining a first navigation obstacle according to a first predetermined navigation route of a first ship; detecting the first navigation obstacle according to a laser radar, and determining a first ship passing space; obtaining first real-time navigation information of the first ship; inputting the first real-time navigation information into a navigation route prediction model to obtain a first predicted navigation route; judging whether the first predicted navigation route is in the first ship passing space or not; if the ship is not in the first ship passing space, obtaining first early warning information; and according to the first early warning information, generating first adjustment navigation information to adjust the first ship. The technical problems that in the prior art, when a ship passes through a bridge space, collision danger is easily caused by yawing, early warning is not accurate enough, and therefore safe driving of the ship is affected are solved.
本发明公开了一种基于激光雷达的船舶偏航预警方法及系统,所述方法包括:根据第一船舶的第一预定航行路线,获得第一航行障碍物;根据激光雷达对所述第一航行障碍物进行探测,确定第一船舶通行空间;获得所述第一船舶的第一实时航行信息;通过将所述第一实时航行信息输入航行路线预测模型中,获得第一预测航行路线;判断所述第一预测航行路线是否处于所述第一船舶通行空间中;若不处于所述第一船舶通行空间中,获得第一预警信息;根据所述第一预警信息,生成第一调整航行信息对所述第一船舶进行调整。解决了现有技术中存在船舶在通过桥梁空间时容易因为偏航而带来碰撞危险,且预警不够准确,从而影响船舶安全行驶的技术问题。
