摘要
在近期如俄乌冲突等多起局部战争中,巡飞弹发挥出了机动灵活、精准打击等战场优势,受到越来越多的关注,但在城市环境中使用巡飞弹,易受到各种各样建筑物的阻挡,影响操作员对战场的研判和对巡飞弹的精准控制。为使操作员快速掌握大规模复杂城市作战场景中的任务环境,辅助操作员高效指挥巡飞弹,从提高操作员态势感知能力的方向对巡飞弹控制站展开研究,设计了一种基于三维动态场景重构和虚拟现实的控制站系统态势显示方法,基于OpenSceneGraph(OSG)开源可视化引擎,采用四叉树管理、金字塔结构的PageLOD动态加载方法,进行巡飞弹任务场景要素管理及建模显示;基于无限串流虚拟现实渲染技术,构建了沉浸式控制站验证系统;设计巡飞弹引导控制试验,通过对任务完成时间及碰撞次数进行客观测试、统计问卷调查表进行主观分析,并对比有无沉浸式的试验效果,验证了该方法易于学习使用且有效提高了操作员的态势感知能力。
In many recent local wars, such as the Russian-Ukrainian conflict, the loitering munition is paid more attention because of the battlefield advantages of mobility and flexibility, precision strikes, etc.However, the use of loitering munition in the urban environment is vulnerable to the obstruction of various buildings, which affects the operator’s judgment of the battlefield and the accurate control of the loitering munition. In order to enable operators to quickly grasp the mission environment in large-scale complex urban combat scenarios and assist operators in efficiently commanding loitering munition, the loitering munition stations is studied from the direction of improving operator situational awareness and a control station system situational display method is designed based on 3D dynamic scene reconstruction and virtual reality(VR).Based on the OpenSceneGraph(OSG) open-source visualization engine, the PageLOD dynamic loading method with quadtree management and pyramid structure is applied to manage and model the elements of the loitering missile mission scenario;an immersive control station verification system is built based on the infinite streaming virtual reality rendering technology;and the loitering munition guidance control test is designed by conducting objective tests on the mission completion time and the number of collisions. By conducting objective tests, statistical questionnaires for subjective analysis, and comparing the effects of the tests with and without immersion, it is verified that the given method is easy to learn and use and can effectively improve the operator’s situational awareness.
