基于OpenGVS的分布式虚拟汽车驾驶视景系统设计与实现

Design and Realization of the Scene System of the Distributed Virtual Vehicle Driving Simulation Based on OpenGVS

针对汽车虚拟驾驶模拟器视景系统对“沉浸感”、“交互感”的要求,设计了分布式虚拟汽车驾驶视景系统,以M u ltiG en C reator为建模软件,O penGV S为开发平台,解决了分布式实时网络结构、视景模型区域分割、三维图形模型导入、视点动态控制、碰撞检测等关键技术问题.实验结果表明:所开发的视景系统能够满足分布式虚拟驾驶模拟系统视景对真实性、实时性和交互性的要求,增强了驾驶视景仿真的沉浸感和交互感.

In this paper, the scene system of the distributed virtual vehicle driving simulation is designed to meet the requirements of the immersion and interactivity of driving vehicle in virtual scene. The scene system is developed using MultiGen Creator as the modeling software ,nd OpenGVS as developing platform. Key technology problems such as the distributed real-time network structure, scene model area segmentation, three dimensional figure model lead, view point control, collision check and etc. are solved. The experimental result shows that the system can meet the requirements of the distributed driving virtual scene about authenticity, real time and interactivity. The immersion and interactivity of the visual simulation is enhanced.
