Modeling of Ship Encounter Risk Perception Based on Riemann Sphere Projection Transformation
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.
