基于虚拟现实的警察“体能+技战术”一体化仿真训练系统设计

Design of police "physical fitness + technology and tactics" integrated simulation training system based on virtual reality

常规警察“体能+技战术”训练会受到外界环境因素的影响,无法满足现今警察的职业需求,故提出基于虚拟现实的警察“体能+技战术”一体化仿真训练系统设计研究。设计系统硬件单元包括3D扫描仪模块、VR眼镜模块、定位器模块、追踪器模块与无线收发装置,软件模块引入虚拟现实技术,设计了视景仿真模块、受训目标检测模块、受训目标追踪模块与总体控制模块。仿真实验结果显示:与现有系统相比较,设计系统的训练场景输出清晰度及帧率较好,线程切换时间与信号量混洗时间较短,充分证明了设计系统运行效率更高,应用性能更好。

Conventional police "physical fitness + skills and tactics" training will be affected by external environmental factors and cannot meet the professional needs of today’s police.Therefore,a design research on the integrated simulation training system of police "physical fitness + skills and tactics" based on virtual reality is proposed.The hardware unit of the design system includes a 3 D scanner module,a VR glasses module,a locator module,a tracker module,and a wireless transceiver.The software module introduces virtual reality technology,and designs a visual simulation module,a trained target detection module,a trained target tracking module,and Overall control module.The simulation experiment results show that:compared with the existing system,the training scene output definition and frame rate of the design system are better,the thread switching time and the semaphore shuffling time are shorter,which fully proves that the design system has higher operating efficiency and application performance better.
