摘　　要：运动捕捉技术在电影产业中的应用极大提升了角色动作的逼真度,而运动风格迁移技术则进一步拓展了这一领域的可能性。运动风格迁移能够将特定情绪、年龄、状态等风格特征迁移至现有的运动捕捉内容中。本文提出一种创新的基于运动细节注意力(MD-ATN)模块的风格化运动生成系统,旨在为动画电影的角色运动风格迁移提供一种高效、直观的解决方案。MD-ATN模块整合了运动的浅层和深层特征,增加了动作细节,从而生成表现力丰富的风格化运动。实验结果表明,该系统在保持运动内容一致性的同时,迁移了指定的运动风格,为动画电影的角色动画制作提供了新的技术手段和创意空间,提升了创作效率。The application of motion capture technology in the film industry has greatly elevated the fidelity of character mo⁃tions.What's more,the technology of motion style transfer has further expanded the possibility of this field.Motion style transfer can apply specific emotional,age,state and other style features to the existing motion capture data.This paper proposes an innovative stylized motion generation system based on the Motion Detail Attention Module(MD⁃ATN),aiming to provide an efficient and intuitive solution for the motion style transfer of characters in animated films.MD⁃ATN module integrates both shallow and deep features of motion,and increases motion details to generate expressive stylized motions.The experimental results show that the system maintains consistency in motion content while transferring specified motion styles,offering new technical approaches and creative space for character animation production in animated films,thus im⁃proving the efficiency of creation.
