Zusammenfassung:The invention provides a ship collision avoidance method based on real-time risk assessment and switching control. The ship collision avoidance method comprises the following steps: acquiring first navigation information of a ship and second navigation information of a navigation obstacle; determining a collision risk index according to the first navigation information and the second navigation information; and if the collision risk index accords with a preset threshold value, making a collision avoidance strategy, controlling the ship to execute a collision avoidance decision, selecting a collision avoidance path and tracking the collision avoidance path. According to the method, collision risk indexes are defined, whether risks exist in the ship navigation process or not is judged according to the collision risk indexes, collision avoidance strategies are formulated, when the ship encounters the risks, related collision avoidance operation can be automatically executed, the risks of the ship are avoided, an
