Ship fire-fighting training system based on virtual reality technique

Abstract

The purpose of this paper is to improve the efficiency and the level of the crew fire-fighting training and save training costs. The whole framework of fire-fighting training system is designed. Fixed water fire extinguishment system, fixed carbon dioxide extinguishment system, and fire-fighting garment model are developed via the three dimension modeling technology. The action of the virtual character is simulated with the method of Inverse Kinematics (IK) applied, which reflects the imagination of the system. The nebulization of the fire and carbon dioxide is realized with utilizing particle system, enhancing the immersion of the system. The collision detection technology improving the interaction of the system is made use of to determine whether an interaction exists between virtual character and equipment, equipment and equipment, carbon dioxide and fire. The prompt information in the process of training can be provided to assist a trainee to accomplish the training. According to the experimental results, the simulation system has a favorable training effect which can be applied to ship fire-fighting training.
