### Overview - Dataset Name: HumanRig - Paper: CVPR2025 - "HumanRig: Learning Automatic Rigging for Humanoid Character in a Large Scale Dataset" - Authors: [Zedong Chu · Feng Xiong · Meiduo Liu · Jinzhi Zhang · Mingqi Shao · Zhaoxu Sun · Di Wang · Mu Xu] - The HumanRig dataset is introduced in the CVPR2025 paper titled "HumanRig: Learning Automatic Rigging for Humanoid Character in a Large Scale Dataset". This work addresses the critical need for a comprehensive dataset and a robust framework for automatic rigging of 3D humanoid character models. HumanRig is a large-scale dataset of AI-generated T-pose humanoid models, all rigged with a consistent skeleton topology. It significantly surpasses previous datasets in terms of size, diversity, complexity, and practical motion applications. ### Dataset Details - Number of Samples: 11,434 - Data Splits: - Training Set: 0-9147 (80%) - Validation Set: 9148-10290 (10%) - Test Set: 10291-11433 (10%) ### Data Structure Each annotated sample in the HumanRig dataset includes the following components: - Rigged T-pose Humanoid Mesh: A rigged 3D mesh of the humanoid character in T-pose. - 3D Skeleton Joint Positions: The positions of the joints in the 3D skeleton. - Skinning Weight Matrix: A matrix that defines the influence of each joint on the vertices of the mesh. - Front-view Image: A 2D image of the humanoid character from the front view. - Camera Parameters: The parameters of the camera used to capture the front-view image. - 2D Skeleton Joint Positions: The positions of the joints in the 2D front-view image. ### Skeleton Joint Order The skeleton joints in the dataset follow a specific order: ``python ['Hips', 'Spine', 'Spine1', 'Spine2', 'Neck', 'Head', 'LeftShoulder', 'LeftArm', 'LeftForeArm', 'LeftHand', 'RightShoulder', 'RightArm', 'RightForeArm', 'RightHand', 'LeftUpLeg', 'LeftLeg', 'LeftFoot', 'LeftToeBase', 'RightUpLeg', 'RightLeg', 'RightFoot', 'RightToeBase'] ` ### Citation If you use the HumanRig dataset in your research, please cite the following paper: `bibtex @article{chu2024humanrig, title={HumanRig: Learning Automatic Rigging for Humanoid Character in a Large Scale Dataset}, author={Chu, Zedong and Xiong, Feng and Liu, Meiduo and Zhang, Jinzhi and Shao, Mingqi and Sun, Zhaoxu and Wang, Di and Xu, Mu}, journal={arXiv preprint arXiv:2412.02317}, year={2024} } ``
