Method and system for assessing and early warning ship collision risk

A system for assessing and early warning ship collision risk, comprising:

• an acquisition unit, configured to acquire hydrological information and meteorological information of a position where a designated ship is located, and acquire navigation information of the designated ship and other ships, wherein the navigation information includes navigation speeds, navigation directions, and positions;
• an evaluation unit, configured to acquire real-time collision risk of the designated ship through evaluation of a trained adaptive collision risk assessment model based on the hydrological information, the meteorological information and the navigation information, wherein the adaptive collision risk assessment model is constructed according to a preset near-miss collision database and a water area where the designated ship is located, the near-miss collision database comprises at least one pair of navigation trajectories, and the minimum relative distance of two navigation trajectories in each pair of navigation trajectories is less than a preset threshold;
• a determination unit, configured to determine a risk level of the designated ship according to the real-time collision risk;
• an output unit, configured to output an early warning message associated with the risk level to the designated ship.

A computer-readable storage medium, in which a computer program is stored, wherein the computer program, when executed by a processor, implements the step of:

• acquiring hydrological information and meteorological information of a position where a designated ship is located, and acquiring navigation information of the designated ship and other ships, wherein the navigation information includes navigation speeds, navigation directions, and positions;
• acquiring real-time collision risk of the designated ship through evaluation of a trained adaptive collision risk assessment model based on the hydrological information, the meteorological information and the navigation information, wherein the adaptive collision risk assessment model is constructed according to a preset near-miss collision database and a water area where the designated ship is located, the near-miss collision database comprises at least one pair of navigation trajectories, and the minimum relative distance of two navigation trajectories in each pair of navigation trajectories is less than a preset threshold;
• determining a risk level of the designated ship according to the real-time collision risk;
• outputting an early warning message associated with the risk level to the designated ship.
