摘　　要：为了舰艇模拟训练的视景动态跟随三维逼真度,通过对舰艇模拟训练实验室虚拟重建设计,提高辅助训练效果,提出基于VR的动态场景渲染下舰艇模拟训练实验室虚拟重建方法。在多武器平台的模拟海战场景下构建舰艇模拟训练实验室的三维背景场景分布模型,在分布式虚拟训练环境下采用Multigen-Creator三维重构方法建立舰艇模拟训练实验室的三维实体结构模型,通过动态场景渲染方法实现对实验室虚拟重建过程中的分离面裁剪和纹理动画序列重组,构建舰艇模拟训练的三维视景场的VR仿真模型,实现对舰艇、来袭武器、拖曳体以及舰艇尾流的建模和模拟训练实验室的三维虚拟重建。仿真结果表明,重建的舰艇模拟训练实验室具有很好的视景仿真和作战模拟训练的动态数据分析能力。In order to achieve dynamic 3D realism in the visual environment of ship simulation training,a virtual reconstruction design for the ship simulation training laboratory is proposed to improve the effectiveness of auxiliary training.A virtual reconstruction method for ship simulation training laboratory based on VR dynamic scene rendering is proposed.A 3D background scene distribution model is built for a ship simulation training laboratory in a simulated naval battle scenario on a multi weapon platform.The Multigen Creator 3D reconstruction method is used to establish a 3D solid structure model for the ship simulation training laboratory in a distributed virtual training environment.The dynamic scene rendering methods are used to achieve separation surface cropping and texture animation sequence recombination during the virtual reconstruction process of the laboratory.A VR simulation model of the 3D visual field is constructed for ship simulation training,and the modeling and simulation of ships,incoming weapons,towing bodies,and ship wake in the training laboratory are achieved.The simulation results show that the reconstructed ship simulation training laboratory has excellent dynamic data analysis capabilities for visual simulation and combat simulation training.
