Simulated Training System of Ship Anchoring Operation Based on Virtual Reality Technology

Abstract

Seldom can trainees be allowed to practice anchoring in current teaching and training for crew. It is quite dangerous, difficult and costly to train and teach the trainees of anchoring operation by using real anchoring equipment. The practical operation teaching and training of ship mooring maneuvers is. In order to improve the training efficiency and save the training cost, an idea of anchoring simulation based on the virtual reality technology has emerged. According to our research on the problems existing in the research and development of the simulation training system for ship anchoring operation. The 3D modeling technology is used to build 3D models of anchoring equipment such as windlass and anchor chains, and the 3D visualization and interactive operation of virtual scene of ships are realized by using Unity 3D engine design. Use inverse dynamics method for virtual human action simulation and A* path finding algorithm for path planning is proposed in the paper, as well as a position-based dynamics (PBD) method to solve the problems of low simulation efficiency and fidelity in the simulation of anchor chains. Besides, a bounding box technology and a continuous collision detection method are employed, respectively, to detect collisions between different objects in a scene. Through the simulation system to carry out practical training for crew, the simulation system can meet the training requirements of ship anchoring.
