基于Leap Motion的电影前期预演人机交互方法

随着虚拟现实(VR)技术的发展,虚拟预演逐渐成为电影制作流程中不可或缺的一环,如何使用自然、多模态的交互方式,结合三维实时渲染引擎,提高电影制作人员在前期预演中的参与感,是该领域的重要研究内容.针对当前虚拟预演中使用的交互方式大多为光学运动捕捉系统等,存在价格昂贵、操作难度高、便携性差等问题.提出一种基于Leap Mo...

Human-computer interaction method in previz based on Leap Motion

With the development of virtual reality(VR)technology,previz has gradually become an indispensable part of the film production.To improve the experience of filmmakers in previz,the utilization of natural multi-modal interaction,combined with 3D real-time rendering engine,has become increasingly important.At present,most of the interactive methods employed in previz are optical motion capture methods,which are expensive,difficult to operate,and poor in portability.This paper presented a human-computer interaction method based on Leap Motion.In addition to obtaining accurate captured data,it greatly reduced cost and the difficulty of operation.Filmmakers can interactively control the trajectory and switch between different motion states of virtual characters through gestures.With the help of motion capture data,filmmakers can directly participate in previz.The verification through previz schemes shows that this method is more natural,friendly,direct and efficient.
