【摘要】 通过动作编辑和运动重用技术为角色添加运动规律,从而形成角色动画,在CAD领域中有着广泛而重要的价值,但这一技术的实现较常应用于卡通动画角色中,缺乏对壁画中的角色动态展现的解决方案。本文提出了一种面向壁画表现的角色动画生成的解决方案。该解决方案的主要贡献在于引入壁画角色动态表现的思想,为壁画角色添加运动规律。系统将美术人员临摹整理完成的壁画序列图像作为系统输入,以输入数据中壁画角色的各个姿态为参考,通过整合和集成已有的关键技术片段,以动作编辑方式得到与壁画角色相关的骨架运动规律。最后为骨架添加蒙皮效果,从而形成一段壁画角色的动画。若将所得动画序列导入模型渲染软件blender中进行风格化渲染,则可获得壁画角色的动画片段。本文针对以上解决方案实现了一个带骨架的壁画角色动画生成系统,该系统的核心技术为动作编辑技术。此外,系统为与辅助软件之间的流程化操作设计了相应接口。然而,本文所实现的系统仅提供了动作编辑功能,对于只存在一幅图像的壁画角色形成动画的可操作性较低,后续工作中可进一步实现运动重用算法,使动画生成系统更为全面。更多还原

【Abstract】 Assigning motion template to characters through motion editing and motion retargeting to generate character animation is of great value in the area of CAD. While the technology is mostly used in cartoon animation, there lacks the solution for animating the originally static characters in fresco paintings.We introduced a system solution for the dynamic display of characters in fresco paintings, the system takes images of fresco paintings copied by artists as input. Then taking the character postures in the paintings as references, the character motion template is generated through motion editing where IK configuration and key frame interpolation technology is used. The character skeleton is then skinned and imported to3D Animation softwares (Eg. Blender) where it will be rendered into the final animation clip with a fresco character.According to the aforementioned system solution, we implemented an frescos style character animation system with basic motion editing functions and designed related software interface to the standard animation pipeline.Motion retargeting methods will be considered in our future work to deal with the problems that may arise in our current system due to the lack of reference images.更多还原
