从演示视频中估计运动代码

Estimating Motion Codes from Demonstration Videos

University of South Florida(南佛罗里达大学)

Maxat Alibayev, David Paulius, Yu Sun

摘要:

运动分类可以将操作编码为二进制编码表示,我们称之为运动代码。这些运动代码本质上表示嵌入空间中的操纵动作,该嵌入空间描述运动的机械特征,包括接触和轨迹类型。使用运动代码进行嵌入的主要优点是,可以使用机器人相关特征更适当地定义运动,并且可以使用这些运动特征更合理地测量它们的距离。在本文中,我们开发了一个深度学习管道,以无监督的方式从演示视频中提取运动代码,以便这些视频中的知识可以正确地表示并用于机器人。我们的评估表明,运动代码可以从EPIC-KITCHENS数据集中的动作演示中提取。

英文摘要:

A motion taxonomy can encode manipulations as a binary-encoded representation, which we refer to as motion codes. These motion codes innately represent a manipulation action in an embedded space that describes the motion's mechanical features, including contact and trajectory type. The key advantage of using motion codes for embedding is that motions can be more appropriately defined with robotic-relevant features, and their distances can be more reasonably measured using these motion features. In this paper, we develop a deep learning pipeline to extract motion codes from demonstration videos in an unsupervised manner so that knowledge from these videos can be properly represented and used for robots. Our evaluations show that motion codes can be extracted from demonstrations of action in the EPIC-KITCHENS dataset.
