Collision Avoidance Method for Ships Using Psychological Characteristics of Navigators

摘要

The present invention relates to a ship collision avoidance method using a psychological character of a ship officer that can provide support allowing ships to avoid collision between one another by using the psychological character of ship officers in order to prevent marine accidents. Herein, a ship collision avoidance method using the psychological character of a ship officer may include a first step calculating a relative distance (RD) and a relative bearing (RB) between two ships by using information of a main ship and information of an opposite ship, a second step estimating a collision risk level (or collision level) (CL) corresponding to the relative distance (RD) and the relative bearing (RB) by using a collision risk (CR) perception of the ship officer, and modeling a Collision Risk Estimation Model (CREM) that converts the estimated results to three-dimensional (3D) coordinate data, a third step calculating a distance of a ship domain (DSD) and the collision level (CL) using the modeled Collision Risk Estimation Model (CREM), a fourth step deciding a reference value of a spatial aspect corresponding to a reference distance for determining a presence of a collision risk between two ships and a reference value of a psychological aspect corresponding to a collision level (CL) for determining a presence of a collision risk between two ships, and a fifth step comparing the relative distance (RD) with the reference value corresponding to the spatial aspect, so as to generate a ship domain (SD) warning for notifying the ship officers that the two ships are within a distance of a possible collision, or comparing a collision risk corresponding to the relative distance (CL(RD)) with the reference value corresponding to the psychological aspect, so as to generate a collision risk (CR) warning for notifying the ship officers that the collision level has reached a level of collision risk.
