Ship collision avoidance control based on improved velocity obstacle method
Journal of Physics: Conference Series, 2023 Abstract The velocity obstacle method has extensive research in collision avoidance, which uses circles to represent robots or ships to find a collision-free velocity. To better describe the motion characteristics of ships, an improved velocity obstacle method based on elliptical ship domain is proposed in this paper.
