基于UE4引擎的虚拟训练系统的设计与实现

Design and implementation of virtual training system based on Unreal Engine 4

针对传统飞行训练系统沉浸感不足,训练场景不够真实的问题,系统模拟了某型飞行器及驾驶训练场景。在UE4中还原了1000km*1000km真实训练超大地景,使用GlobalMapper准确选择区域并通过WorldMachine生成了准确地形;在UE4中利用蓝图系统集成并处理模型等各类资源和功能,通过精细贴图实现8K超高清画面;通过共享内存等手段进行仪表盘、飞机驾驶数据的实时交互。设置了多个视角,既提高了驾驶操作的逼真感,又方便用户进行场景漫游,同时支持HTC vive与设备进行VR交互,极大增加了虚拟训练系统的沉浸感。

In order to solve the problem of the lack of immersion and realistic training scenes in the traditional flight training system, this system simulates a certain type of aircraft and pilot training scenes. In UE4, a 1000 km*1000 km real training super-large landscape is restored, which uses GlobalMapper to accurately select area and generate the accurate terrain through WorldMachine. In UE4, the blueprint system is used to integrate and process various resources and functions such as models, and 8 K Ultra HD images are realized through fine mapping. Real-time interaction of instrument panel and aircraft polit data is carried out through shared memory and other means. Multiple perspectives are set, which not only improves the sense of realism of driving operation, but also facilitates users to conduct scene exploration. At the same time, HTC Vive is supported for VR interaction with devices, greatly increasing the immersion of virtual training system.
