摘要
中小成本影视剧组的虚拟预演环节,通常采用预演软件、关键帧动画、传统动作捕捉以及物理模拟等方法控制虚拟角色运动.然而,这些方法分别存在预演精度不足、耗时耗力、需配备专业设备及制作流程复杂等缺陷.针对上述问题,本文提出一种新的虚拟角色控制方法,利用AI动作捕捉技术实现了虚拟角色的运动控制,并进行了虚拟预演短片制作.通过简化流程,实现了虚拟角色的动作捕捉,从而扩展了虚拟预演的应用范围.实验对比表明,该方法所呈现的数据精度能够满足虚拟预演需求,无需佩戴专业设备即可实现近似实时的效果,同时该方法性价比较高,且场地限制较小.
Abstract
The previsualisation for virtual character movement in limited budget film and television crew normally controlled by PreViz software,key frame animation,traditional motion capture and physical simulation-based techniques,which are respectively characterised by low accuracy,time-consuming and laborious,demands for professional equipment and com-plexity of the production process,and other shortcomings.Aiming at resolving the above problems,this study develops a new method,which realizes the motion control for virtual characters with the help of AI-driven motion capture,and carries out the production of PreViz.The proposed method turns out with better effects through simple processes and expands the scope of application of PreViz.According to the data of experimental comparison,this method can not only meet the re-quirements for production with PreViz to a certain extent,but also presents near real-time effects without wearing profes-sional equipment.Last but not the least,it has the advantages of high cost-effectiveness with small site constraints.
