Research On 3D Simulation Technology Of Ship Motion And Attitude Based On Reality Enhancement

With the continuous development of computer graphics and other theories,people begin to simulate the real environment by computer.For the simulation of virtual environment,we need to improve the immersion and reality as much as possible.With the application of virtual reality(VR)technology more and more widely,another technology similar to VR technology,augmented reality(AR)technology brings people another visual experience.It is the trend of teaching reform in the next stage to apply reality enhancement technology to teaching reform.There are many problems in the traditional education assisted reality enhancement system,such as large memory occupation,unable to run across platforms,and difficult to update.On the basis of solving the above problems and web application,this paper studies,designs and implements the ship motion simulation system based on reality enhancement,and the specific contents are as follows:First of all,according to the relevant requirements of the system,the overall technical scheme of the ship motion simulation reality enhancement system is proposed,including the construction of the server,the modeling of the three-dimensional static mesh,the drawing of the two-dimensional map,the construction of the front-end interaction module and the construction of the reality enhancement module.Secondly,according to the rendering problem of the 3D static mesh material in the ship motion simulation reality enhancement system under different illumination,the PBR based material rendering algorithm is studied,and the experimental environment is built to verify and test the rendering effect of the material.At the same time,aiming at the problem of image recognition in reality enhancement system,this paper studies the algorithm of image feature point extraction based on orb,and validates the algorithm with the pictures applied in the system,which proves the feasibility of the algorithm.Finally,the development of the ship motion simulation reality enhancement system is completed.The system mainly includes: upload of server static resources,visualization of 3D scene,realization of 3D interactive module,realization of touch screen sliding effect and Realization of user interface setting.
