Research And Development Of Visual Simulation System Of Ship Based On Virtual Reality Technology

The development of navigation industry plays an important role in promoting the development of a country.Seventy percent of the earth's area is covered by sea water.With the rapid development of Global trade,it is very important for us to strengthen the maritime defense forces of the super power.Ships,as an important pillar of trade and maritime defense,have become more and more extensive in recent years.With the rapid development of information technology and VR technology,the ship simulation system based on virtual reality technology has become a hot topic.Since ancient times,people have been working on the research of ships.In the aspect of ship motion,the motion equations of the motion of the particle motion of the ship to the 3D motion are generated.In the actual research work,it is commonly used in the pool experiment method,which is to reduce the size of the ship in accordance with the proportion of the relevant research in the pool.The same can be designed and analyzed by using the ship model and the theoretical calculation in the laboratory.These two common methods are the same problem,that is,the research funding is higher,demanding on the experimental site.In the traditional ship simulation test,the application of virtual reality technology in the simulation of-the ship is still very narrow,mostly for pipeline simulation,the rudder cabin simulation and other hardware in the loop simulation for students to learn and use.Based on the analysis of the development and application of virtual reality technology at home and abroad,this paper selects the virtual reality software unity,and the research and development of the visual simulation system of the shipis carried out.Which contains three systems:according to the ship's attitude change,the simulation system of ship motion is established;the simulation system of damaged water immersion in the cabin;the virtual cabin roaming system.And realize the function of real-time simulation and interactive control.
