Intelligent collision avoidance system and method for ships based on maneuverability modeling

Abstract: The invention provides a ship intelligent collision avoidance system based on manoeuvrability modeling, comprising a state sensing subsystem, wherein the state parameters of the ship and the positioninformation of an obstacle are obtained; the maneuverability modeling module processes the ship's own state parameters, constructs the sample pairs, carries on the ship maneuverability on-line modeling, and predicts the ship's possible arrival position at the next time under all feasible maneuverability. The intelligent collision avoidance module combines the position information of the obstacle,Binary navigable area information and collision avoidance rules are used to carry out dynamic path planning. In path planning, the maneuverability modeling module predicts the possible arrival position of the ship at the next time as a constraint, outputs a reasonable planning path point sequence, and decouples it into a heading tracking sequence and a speed tracking sequence. Track the planned real-time heading and speed respectively. The invention realizes the intelligent collision avoidance decision of the ship on the basis of the on-line prediction of the ship maneuverability, and realizesthe safe and autonomous navigation of the ship.

A study of sensor fusion technology for collision avoidance system

Abstract: In Japan, development of safety technology, including infrastructure for automobiles, is an important social task as the death toll from traffic accidents exceeds 10,000 every year. To counter the problem, the Ministry of Transport has been carrying out a 5-year program called the Advanced Safety Vehicle (ASV) Program. Under the program, Japanese automakers are involved in the development of an experimental ASV. This paper discusses a foward-looking sensor for an automatic collision-reduction braking system that was developed during the research and development of ASV project. The sensor is composed of two CCD cameras and a millimeter wave radar. The cameras recognize curve radius and preceding vehicles. The curve radius is used to control beam steering of the millimeter wave radar. The recognized distance by the cameras and detected distance by the radar are verified with each other to obstacle detection.

Collision avoidance system using short pulse signal reflectometry

Abstract: A collision avoidance system for rapid transit vehicles employing baseband radar principles in which signals with duration in the order of nanoseconds are transmitted down track along a surface wave transmission line. Reflections from a passive target located on the preceding vehicle are processed to establish the distance between the vehicles to within an accuracy previously unachievable.

Dynamic Collision Avoidance System for a Manipulator Based on RGB-D Data

Abstract: The new paradigms of Industry 4.0 demand the collaboration between robot and humans. They could help and collaborate each other without any additional safety unlike other manipulators. The robot should have the ability of acquire the environment and plan (or re-plan) on-the-fly the movement avoiding the obstacles and people. This paper proposes a system that acquires the environment space, based on a kinect sensor, performs the path planning of a UR5 manipulator for pick and place tasks while avoiding the objects, based on the point cloud from kinect. Results allow to validate the proposed system.

Hybrid air collision avoidance system

Abstract: A hybrid air collision avoidance system (HACAS) is an air collision avoidance system with extended existing air avoidance capabilities and incorporated with new hybrid capabilities to perform hybrid air collision prediction and hybrid air collision avoidance. This system works in collaboration with two other systems, hybrid ground collision avoidance system, and obstacle avoidance dispatcher and resolver module to form a bi-directional feedback network for processing and exchanging of verification and validation collision avoiding data. With the embedded hybrid prediction and avoidance processing capabilities, the system not only can refine air collision avoidance solution to eliminate any induced ground collision situation, but also provide verification for ground collision avoidance resolution in the air domain; and subsequent validate the final avoidance solution.
