摘要
船舶操作复杂程度的增加,对虚拟航海场景提出了更高的要求,常规虚拟航海场景设计系统存在着加载时间过长,显示效果较差的缺陷,无法满足现今船员训练的需求,提出基于虚拟现实的虚拟航海场景优化系统设计研究。设计系统硬件包括视景机优化单元、虚拟控制设备选取单元与虚拟现实装置电路结构优化单元;软件包括图像加速绘制模块、航海场景加载速度优化模块与航海场景显示效果优化模块。通过上述硬件单元与软件模块的设计,实现了虚拟航海场景优化系统的运行。实验数据显示:应用设计系统后,缩短了场景加载时间,减小了场景文件大小,表明设计系统应用性能较好。
With the increase of the complexity of ship operation,higher requirements are put forward for virtual navigation scenes.The conventional virtual navigation scene design system has the defects of too long loading time and poor display effect,which cannot meet the needs of current crew training.Therefore,a virtual realt-based optimization system design for virtual navigation scenes is proposed.The design system hardware includes the visual machine optimization unit,the virtual control equipment selection unit and the virtual reality device circuit structure optimization unit.The software includes image acceleration drawing module,navigation scene loading speed optimization module and navigation scene display effect optimization module.Through the design of the above hardware unit and software module,the operation of the virtual navigation scene optimization system is realized.The experimental data show that the application of the design system can shorten the scene loading time and reduce the size of the scene file,indicating that the design system has a good application performance.
