采用Unreal Engine的多人在线虚拟驾考系统

Research on Multiplayer Online Virtual Driving Test System Based on Unreal Engine

以Unreal Engine为渲染引擎,构建一个基于多人在线的虚拟驾考系统,研究其中的地形构建、场景渲染、车辆运动工况、多终端中车辆平顺性等关键技术。利用数字高程模型等数据,实现驾考场景的地形构建;利用Unreal Engine为渲染引擎、HTC Vive为头显设备,实现了驾考系统的高质量可视化与友好的交互体验;基于车辆行驶动力学算法,实现汽车运动工况模拟;利用滞后补偿算法,实现多人在线架构下的车辆平顺性需求。系统的测试与分析表明,上述的虚拟交互设计极大地增强了场景真实感和用户体验性。

A multiplayer online virtual driving test system is built to study key technologies such as terrain construction,scene rendering,vehicle motion conditions,and vehicle ride comfort in multiple terminals by using Unreal Engine as the rendering engine.The terrain construction of driving test scenes is realized by using data such as digital elevation models;using Unreal Engine as the rendering engine and HTC Vive as the head-mounted display device,high-quality visualization and friendly interactive experience of the driving test system are achieved;based on vehicle driving dynamics algorithm,the simulation of automobile motion conditions is realized;the vehicle smoothness requirements under the multiplayer online architecture is achieved by using the lag compensation algorithm.System testing and analysis show that the above virtual interaction design greatly enhances the realism of the scene and user experience.
