Comprehensive Dataset for Modeling Interactions Between Multiple Humans and Multiple Objects in Diverse Contextual Environments

Core Concepts

The core message of this article is to introduce HOI-M3, a novel large-scale dataset that captures interactions involving multiple humans and multiple objects within diverse contextual environments, in order to facilitate research on data-driven modeling of complex human-object interactions.

Abstract

The article presents the HOI-M3 dataset, which is designed to capture interactions involving multiple humans and multiple objects within a contextual environment. Key features of the dataset include:

Multiple Humans and Objects: Each sequence involves a minimum of 2 persons and 5 objects, which is the first real-world 3D multiple human-object dataset with accurate 3D motion capture.

High Quality: Sequences are recorded within daily-style rooms with 42 synchronized camera views, and inertial measurement units (IMUs) are embedded in each pre-scanned object to ensure accurate human-object tracking labels.

Large Size and Rich Modality: The dataset records over 20 hours of interactions with both RGB and inertial sensors, providing segmentation annotations, pre-scanned object geometry, and accurate human-object interaction tracking labels.

The authors also introduce two novel downstream tasks based on the HOI-M3 dataset:

Monocular Capture of Multiple HOI: A single-shot learning-based method is proposed to estimate multi-person and multi-object 3D poses from a single image.

Unstructured Generation of Multiple HOI: The authors tailor diffusion models to generate intricate social interactions involving multiple people and objects.

Extensive experiments demonstrate that the HOI-M3 dataset is challenging and worthy of further research on modeling multiple human-object interactions and behavior analysis.
