The invention discloses a ship collision risk degree judgment method. The method comprises the steps: acquiring ship navigation data to be processed; performing data preprocessing on the to-be-processed ship data to obtain processed data; identifying the ship navigation features through a nonlinear support vector machine decision tree model, and determining the collision risk degree of the ship and the target ship. The invention discloses a ship collision risk degree discrimination system. The ship collision risk degree discrimination method and system can be applied to mass data while improving the classification precision.
