The invention discloses a navigation risk assessment and path planning method for a ship in a narrow channel. The method comprises the following steps: solving a safe navigation field of the ship; setting a current concerned area of the ship; acquiring a channel safe driving area; calculating a ship navigation risk; and planning a navigation path with the minimum risk in the navigation channel. According to the method, firstly, the area of the intersection part of the ship safety domain model and the narrow water channel is obtained, then, an area set is obtained by continuously changing the ship position and ship attitude traversal, and finally, the ship collision avoidance path is obtained by continuously searching the position and attitude of the ship when the area is the minimum value in the area set. The method is not limited by a specific ship safety domain model, and a quantitative navigation risk assessment result can be given. Based on the quantitative navigation risk evaluation result provided by the invention, the navigation path in the narrow channel can be reasonably planned, so that the navigation path with the minimum navigation risk is obtained, and the path planning of the safe driving of the ship is realized.

    本发明公开了一种狭窄航道内船舶航行风险评估及路径规划方法,包括以下步骤:求取船舶安全航行领域;设定船舶当前关注区域;获取航道安全行驶区域;求取船舶航行风险;规划航道内风险最小的航行路径。本发明首先对船舶安全领域模型与狭窄水道的交集部分求得面积,然后通过不断改变船舶位置与船舶姿态遍历求出面积集合,最终通过在面积集合中不断寻找面积最小值时船舶的所在位置与姿态来获得船舶的避碰路径,本发明不受限于具体船舶安全领域模型,并可以给出定量的航行风险评估结果。基于本发明给出的定量航行风险评价结果,可对狭窄航道内的航行路径进行合理规划,从而获得航行风险最小的航行路径,实现了船舶安全行驶的路径规划。
