Design And Implementation Of UUV Visual Simulation System For Exercise Training

Visual simulation technology is usually regarded as one of the key technologies for unmanned,intelligent and other high technology fields of military exercises and counter training,with the advantages of low cost,low risk and high security,so it is increasingly concerned and valued by scholars at home and abroad.Currently,with the rapid changes in artificial intelligence,unmanned equipment and other cutting-edge technologies,the maritime warfare model gradually presents the development trend of unmanned,networked and intelligent,and the underwater unmanned equipment represented by UUV is the main combat force in the future underwater battlefield.In view of this,this paper focuses on the future unmanned marine battlefield,for the UUV underwater activity state is difficult to observe and the needs of naval warfare simulation exercise training,proposed based on the view simulation technology to build underwater unmanned view simulation training system,the specific research content is as follows.1.For the needs of the UUV training system on the virtual environment of the real sea,research on the construction of three-dimensional spatial model and visualization technology of environmental elements.Firstly,based on the actual undersea terrain data of Xi Sha Antelope Reef,the undersea terrain simulation model is constructed using computer graphics technology,and the undersea virtual simulation scene is constructed by combining with the actual geological and geomorphological textures;secondly,the wave spectrum modelling method based on FFT is adopted to construct the surface wave simulation model;finally,virtual simulation technologies such as sky box,fog effect and sound effects are integrated to realize the simulation and visualization of the UUV virtual environment of the real sea.2.In order to achieve the goal of driving the UUV vision simulation system in real time,the UUV 3D geometric model construction method and UUV kinematic model are studied.The simulation results show that the simulation data of the motion model can simulate the actual UUV sensor data to drive the view simulation system.3.The process of implementing the UUV visual simulation system is studied for the functional requirements of UUV exercises.The online and offline data-driven UUV 3D geometric model motion reproduction in a virtual 3D environment is realized using network communication and database technology;the logic control of Unity3 D components is used to realize the functions of 2D geo-mapping display and perspective switching;the collision detection and particle system is used to simulate the sonar detection effect and underwater explosion effect;the interaction between the system and the operator is realized through the interactive event mechanism;The system is connected to the HTC Vive VR device for multidimensional scenario access and is used to train the operator on the UUV anti-mine mission.The results show that the system is able to train the UUV during the mission while ensuring real-time and interactivity.The Unity3D-based UUV visual simulation system in this study improves the fidelity and interactivity of real time compared to traditional visual simulation engines and underlying graphics engines.The system is designed to meet the operator’s needs for UUV mission training.
