基于DI-Guy的人体视景仿真研究与应用

Human Visual Simulation Research Based on DI-Guy

本文分析了目前几种典型的虚拟人系统,着重研究了基于DI-Guy的人体视景仿真技术,讨论了虚拟人的开发环境,分析了两种虚拟人生成方法(ACF配置实现及API编程实现),论述了虚拟人实时运动中的若干问题;着重介绍了虚拟人自定义动作实时驱动方法,克服了用动作库中成型动作驱动的缺点,提高了人体视景仿真的真实性;给出了仓库调度仿真系统应用范例。结果表明,包含多个人体实体的虚拟场景在HP6200上的运行帧频大于28帧/秒,而且人体动静态效果逼真,满足一般工程应用需求。

Analyzing some current typical virtual human systems, the paper focuses on the visual simulation based on DIGuy,discusses the development environment, analyzes two methods of virtual man generation（based on Lynx Prime and API） ,and describes some problems in virtual human development. A new real-time driving method is presented to fulfill the requests of complex and precise human motion simulations, it overcomes the traditional method of preform motion driving. The results indicate that the dynamic and static effect of human is lifelike. The operational frame frequency based on HP6200 is no more than 28 frames/sec,which meets the demands of general engineering applications.
