AI总结:

Video2MR利用AI动作捕捉将2D教学视频转化为3D化身,通过姿势对比、轨迹可视化、时间操控和视角重定位等增强技术,在Hololens 2上提供更沉浸的体育学习体验。

摘要:

本文介绍了Video2MR,一个混合现实系统,能够从2D视频中自动生成3D体育和锻炼指令。混合现实指令在体能训练方面具有巨大潜力,但现有工作创建这些3D体验需要大量的时间和成本。Video2MR通过利用AI驱动的动作捕捉(DeepMotion)将网上可用的任意教学视频转化为MR 3D化身,从而克服了这一限制。然后,它通过以下增强技术自动增强化身运动:1)对比并突出用户与化身姿势之间的差异,2)可视化特定身体部位的关键轨迹和运动,3)利用身体运动操控时间和速度,以及4)在空间上重新定位化身以提供不同视角。该系统基于Hololens 2和Azure Kinect开发,我们展示了多种使用案例,包括瑜伽、舞蹈、足球、网球和其他体育锻炼。研究结果证实,与现有的2D视频指令相比,Video2MR提供了更具吸引力和趣味性的学习体验。

英文摘要:

This paper introduces Video2MR, a mixed reality system that automatically generates 3D sports and exercise instructions from 2D videos. Mixed reality instructions have great potential for physical training, but existing works require substantial time and cost to create these 3D experiences. Video2MR overcomes this limitation by transforming arbitrary instructional videos available online into MR 3D avatars with AI-enabled motion capture (DeepMotion). Then, it automatically enhances the avatar motion through the following augmentation techniques: 1) contrasting and highlighting differences between the user and avatar postures, 2) visualizing key trajectories and movements of specific body parts, 3) manipulation of time and speed using body motion, and 4) spatially repositioning avatars for different perspectives. Developed on Hololens 2 and Azure Kinect, we showcase various use cases, including yoga, dancing, soccer, tennis, and other physical exercises. The study results confirm that Video2MR provides more engaging and playful learning experiences, compared to existing 2D video instructions.
