摘要
针对专业视频会议和视频指挥业务保障人员音视频设备部署训练手段匮乏的问题,给出了一种基于虚拟现实的音视频设备三维放置模拟训练系统,依托Unity3D等虚拟现实软件,真实还原了音视频设备外观以及设备音视频效果;通过对虚拟世界空间坐标和屏幕空间坐标的计算,结合NGUI中的鼠标控制方法,实现了对设备三维空间的简单控制;深入研究Unity3D角度控制原理,控制四元数和欧拉角间的关系,精确还原了摄像头转动特性和动画;通过塑造碰撞体并结合协程函数进行时序控制,实现了对用户成绩的高效识别和反馈。系统已在相关教学班中运用,用户操作上手快,满意度良好。
To solve the issue that training methods of deployment of AV devices in professional video conference and video commanding service are insufficient,an AV(audio and video)device placement simulation training system based on virtual reality is proposed in this paper.Relying on virtual reality software such as Unity3D,the appearance of AV equipment and the audio and video effects of the equipment are truly restored.By calculating the virtual world space coordinates and screen space coordinates and combining with the mouse control method in the NGUI,a simple control of the three-dimensional space of the equipment is achieved.Considering Unity3D angle control principle deeply,controlling the relationship between the Quaternion and Euler angle,camera rotation characteristics and animation are accurately restored.By shaping the collision body and controlling the Coroutines function for timing,an efficient recognition and feedback method of user’s performance is obtained.The system has been used in the course,and the operation is simple and users have strong willing to use the system.
