The invention provides a marine ship collision avoidance early warning method and system and a chart plotter. The method comprises the steps: obtaining the navigation information of the ship, and recognizing a temporary navigation obstacle to obtain a recognition result; obtaining at least one early warning point in the current route of the ship, wherein at least one early warning point comprisesat least one of a navigation channel obstacle navigation object position point, a historical collision accident occurrence place and a temporary obstacle navigation object position point; judging whether the distance between the ship and the current early warning point is larger than the early warning distance or not according to the navigation information and the recognition result, and obtaininga judgment result, wherein the current early warning point is the early warning point closest to the ship in at least one early warning point; and if the judgment result is negative, generating earlywarning information, and performing marine collision avoidance analysis according to the current early warning point to obtain manipulation matters needing attention. According to the method, early warning is carried out on known dangers and unknown potential collision dangers, the ship collision accident rate can be reduced, the collision risk is reduced and the cost price is not increased in the aspect of hardware equipment.

    本发明提出一种船舶海上避碰预警方法、系统和海图机,该方法包括:获取本船的航行信息,以及识别临时障航物得到识别结果;获取本船当前航线中的至少一个预警点,其中至少一个预警点包括航道障航物位置点、历史碰撞事故发生地点和临时障航物位置点至少其中之一;根据航行信息结合识别结果判断本船到当前预警点的距离是否大于预警距离,得到判断结果,其中当前预警点为至少一个预警点中到本船的距离最近的预警点;如果判断结果为否,则产生预警信息,并根据当前预警点进行海上避碰分析,得到操纵注意事项。本发明对已知危险和未知的潜在碰撞危险进行预警,可以减小船舶碰撞事故率、降低碰撞风险,且在硬件设备方面未增加成本价格。
