二三维互动映射的潜望镜视景仿真系统设计与实现

Design and realization of periscope training simulation system based on interaction of 2D and 3D scene simulation

针对常规潜艇航行训练费用高、周期长、风险高等问题,基于虚拟现实技术并结合潜艇操纵运动理论,开发设计潜望镜视景仿真系统。首先阐述了训练系统的框架,并对各功能模块进行描述。基于军用电子海图开发教练员控制系统,可以进行训练环境设置与场景的控制。通过双缓冲技术实现电子海图的绘制,并应用TrueType字体工具建立常用军标库,实现了军标的绘制。通过实拍纹理数据建立海洋场景模型库,并应用Vega Prim e实现了系统的视景渲染驱动。采用DR算法弥补了系统网络通信量的不足,满足了视景仿真的实时性要求。

The traditional submarine voyage training has problems of high cost,long period and high risk.In this paper,a periscope training simulation system was proposed based on virtual reality and submarine control theory.At first,the construction of the system and the functions of modules were described.The coach control system based on digital chart was realized,which can achieve functions of training environment and parameters setting.The model library of virtual ocean scene was built and then the scene was rendered by Vega Prime.In order to remedy the deficiency of the network,a DR algorithm was used,which can satisfy the real-time requirements of scene simulation.
