Study of Simulation System of Deep Submergence Rescue Based on Virtual Reality

援潜救生是一项必要而又复杂的系统工程,存在着很多不确定因素,为了对救援方案进行评估、验证,提高救援能力,应用虚拟现实技术,建立了援潜救生仿真系统。系统采用离散调度方法获取初始调度方案,通过人因工程分析、动力学及流体力学计算等反映实体的物理行为,利用人机接口与系统进行交互,验证与完善初始救援方案。构建了数据输入、场景建模与场景驱动的系统框架,并对系统的关键技术进行了详细描述。该仿真系统的实现为海上救援提供了必要的理论依据及直观的视觉表现。

Submarine rescue is a necessary and complicate project with many uncertainties. To evaluate and validate rescue scheme, a simulation system of deep submarine rescue was developed based on virtual reality. In the system, an initial schedule was obtained by applying discrete scheduling approach, physical behaviors of entities were reflected by human factors analysis, dynamics and hydrodynamics calculation, the initial rescue scheme was validated and improved by human- computer interaction. Data inputting, scene modeling and scene driving were established, and key technologies of the system were described detailedly. The simulation system supplies necessary theory basis and direct visual expression for submarine rescue.
