Abstract

The invention discloses a ship autonomous sailing collision avoidance method based on a safety field, which comprises the following steps: determining an encounter situation between two ships by utilizing geographic coordinates and sailing parameters of the ship and other ships, and dividing collision avoidance strategies of the two ships into three types according to the encounter situation between the two ships so as to perform collision avoidance in different modes. Therefore, intelligent collision avoidance decision of the ship is realized, the ship can sail automatically according to a preset route when no obstacle exists, and energy consumption of the ship is reduced as much as possible.

Description

Technical field [0001] The present invention relates to the technical field of autonomous ship navigation, and in particular to a collision avoidance method for autonomous ship navigation based on the safety field. Background technique [0002] When surface ships encounter static and dynamic obstacles such as islands, ships, and floating objects on the sea during navigation, they can adaptively adjust their course and speed according to the International Collision Avoidance Regulations at Sea (COLREGS) to avoid various obstacles. It can realize the intelligent obstacle avoidance decision-making of the ship; when there are no obstacles, it can automatically sail according to the preset route and reduce its own energy consumption as much as possible. However, the International Ocean Collision Avoidance Regulations (COLREGS) are very vague in dividing encounter situations between ships, and ship pilots can only use the rules to avoid collisions based on their feelings. Conten...
