The invention belongs to the technical field of navigation, and discloses an inland river bridge group water area ship navigation collision avoidance method and system, and the method comprises the steps: carrying out the environment modeling based on an electronic river map; designing a bridge group collision avoidance path planning algorithm; and designing a bridge group navigation mark auxiliary yaw early warning system. An inland river bridge group water area ship navigation collision avoidance system is established, and environment information is obtained based on an electronic river map and processed into an environment model capable of being directly utilized. A ship-bridge group is used as a research object, a ship-bridge group collision-free path is established based on a voronoi method, factor constraints are considered, and a ship bridge group operation collision avoidance strategy is researched. The navigation track of the ship is predicted, navigation mark acousto-optic early warning prompt is supplemented for the ship yawing or having the collision risk, and the bridge group water area ship yawing early warning function is achieved.

    本发明属于航海技术领域,公开了一种内河桥群水域船舶航行避碰方法及系统,该方法包括:基于电子江图环境建模;桥群避碰路径规划算法设计;桥群航标辅助偏航预警系统设计。本发明建立内河桥群水域船舶航行避碰系统,基于电子江图获取环境信息,处理成为可直接利用的环境模型。以船舶‑桥群为研究对象,基于泰森多边形方法(voronoi方法),建立船舶桥群无碰撞路径,并考虑因素约束,研究船舶过桥群操纵避碰策略。对船舶航行轨迹进行预测,对偏航或存在碰撞风险船舶辅以航标声光预警提示,实现桥群水域船舶偏航预警功能。
