三维汽车群组动画仿真研究综述

Survey of Three-Dimension Traffic Animation

近年来,随着虚拟现实技术的不断发展,三维汽车群组动画仿真已经成为计算机图形学领域的热点研究方向.文中对三维汽车群组动画仿真涉及的技术进行综述.首先对作为汽车运动发生载体的交通路网建模技术做了全面的分析和总结;其次根据汽车运动建模方法所采用的技术不同,将现有方法分为一维跟车方法、流体方法、介观方法、混合方法、路径规划方法、个体规则方法以及数据驱动方法七大类,并详细阐述了每一类的原理、特点以及优缺点对比;最后结合需求总结现有工作中存在的不足,提出了一些可以继续深入研究的问题.

Recently, as the development of virtual reality techniques, traffic animation turns to be one of hotspots in computer graphics. This paper provides a survey of the methods in three-dimension traffic animations. First,we present a structured review of methods of road networks, which are the carriers of vehicles. Second, we describe vehicle movement simulations from seven perspectives, including one-dimension car-following method,continuum method, mesoscopic method, hybrid method, path-planning method, rule-based method and data-driven method. We detail their principles, advantages and drawbacks. Finally, we point out some open research areas and possible future directions
