📝 摘要(中文)

人类与物体的交互建模近年来成为一个新兴的研究方向。然而,由于严重的遮挡和复杂的动态变化,捕捉人类与物体的交互是一项极具挑战性的任务。这需要理解3D人类姿态、物体姿态以及它们之间的交互。为此,本文提出了首个RHOBIN挑战,旨在将人类与物体重建及交互建模的研究社区聚集在一起,讨论技术并交流思想。挑战包括三个轨道,专注于从单目RGB图像中进行3D重建,尤其是在复杂交互场景下。该挑战吸引了超过100名参与者,提交了300多份作品,显示出研究社区的广泛兴趣。本文描述了挑战的设置,并详细讨论了每个轨道的获胜方法。

📄 摘要(原文)

Modeling the interaction between humans and objects has been an emerging research direction in recent years. Capturing human-object interaction is however a very challenging task due to heavy occlusion and complex dynamics, which requires understanding not only 3D human pose, and object pose but also the interaction between them. Reconstruction of 3D humans and objects has been two separate research fields in computer vision for a long time. We hence proposed the first RHOBIN challenge: reconstruction of human-object interactions in conjunction with the RHOBIN workshop. It was aimed at bringing the research communities of human and object reconstruction as well as interaction modeling together to discuss techniques and exchange ideas. Our challenge consists of three tracks of 3D reconstruction from monocular RGB images with a focus on dealing with challenging interaction scenarios. Our challenge attracted more than 100 participants with more than 300 submissions, indicating the broad interest in the research communities. This paper describes the settings of our challenge and discusses the winning methods of each track in more detail. We observe that the human reconstruction task is becoming mature even under heavy occlusion settings while object pose estimation and joint reconstruction remain challenging tasks. With the growing interest in interaction modeling, we hope this report can provide useful insights and foster future research in this direction.
