摘要
文中提出一种基于黎曼球面投影变换的船舶会遇风险感知模型,将船舶相对运动轨迹投影为黎曼球面上的相对曲线运动,利用黎曼球上船舶的相对速度与相对距离构建会遇风险模型.基于三种会遇局面和实际事故案例进行仿真,并基于案例与传统模糊综合评价模型作对比分析模型可靠性.结果表明:所提模型能有效地评估船舶会遇风险,实时可视化输出更为直观,便于辅助船舶避碰决策.
Abstract
A ship encounter risk perception model based on riemann sphere projection transformation was proposed,and the relative motion trajectory of the ship was projected as the relative curve motion on the riemann sphere.Based on the relative speed and distance of ships on Riemann sphere,the en-counter risk model was constructed.Based on three situations and actual accident cases,the simula-tion was carried out,and the reliability of the model was analyzed by comparing the case with the tra-ditional fuzzy comprehensive evaluation model.The results show that the proposed model can effec-tively evaluate the risk of ship collision,and the real-time visual output is more intuitive,which is convenient to assist the decision-making of ship collision avoidance.
