蛟龙号下潜及水下作业过程的交互仿真开发

Development of Interactive Simulation of Dive and Underwater Operation Process of Jiaolong

为解决当前从事深潜工作的实操训练存在实施难、安全风险大等问题,基于虚拟现实技术设计不受时间和地点限制的蛟龙号下潜及水下作业过程的仿真系统。运用三维建模技术构建蛟龙号、支持母船等关键结构的三维模型;建立A型架的运动数学模型,模拟其运动过程;结合三维交互技术、虚拟漫游技术以及碰撞检测技术实现人机交互与漫游;从用户体验角度出发,对实际的下潜及水下作业过程进行仿真实现操纵交互功能。经测试,该仿真系统基本满足目前对载人深潜器潜航员的训练需求。

In order to solve the problems of difficult implementation and high safety risk in the practical training of deep submarine work at present, the simulation system of dive and underwater operation process of jiaolong is designed based on the virtual reality technology, which is not limited by time and place. The 3D modeling technology is used to construct the 3D model of the key structures such as the jiaolong and the mother ship. A mathematical model of A frame motion is established to simulate the motion process. Human-computer interaction and roaming are achieved by using 3D interactive technology, virtual roaming technology and collision detection technology; From the prospective of users＇ experience, actual dive and underwater operation process are simulated to realize the maneuvering interactive function. The test results show that the simulation system basically meets the training needs of the manned deep submersible at present.
