PointCloud-C @ ECCV 2022

The 1st Challenge on Point Cloud Robustness under Corruptions


The 1st PointCloud-C challenge is hosted in conjecture with the ECCV'22 SenseHuman workshop. It aims at providing a comprehensive test-suite for point cloud robustness analysis under corruptions. It includes two seperated sets for point cloud classification and part segmentation, respectively. For more details, please refer to our technical reports.

    To participate, please register at the official CodaLab page here.


    Please prepare the data from the following resources:

    # Description Size Number of Items Data Format Link
    1 Classification 0.33GB 1 .zip Google Drive
    1 Part Segmentation 0.76GB 1 .zip Google Drive

    Note: The above data are generated for this competition only. To participate in the official ModelNet-C and ShapeNet-C benchmark, please refer to this page.


    Users are required to use only the official ModelNet and ShapeNet training set during training for the ModelNet-C track and the ShapeNet-C track, respectively. Other training datasets are only allowed when they are unlabelled or used in an unlabelled way. Corruptions that are part of ModelNet-C and ShapeNet-C are strictly NOT allowed to be included as training augmentations. No test-time model ensemble is allowed.


    In this competition, we choose DGCNN (Wang et al., 2018), a classic point cloud recognition method, as the baseline to normalize the severity of different corruptions. We use the mean corruption error (mCE) as the primary metric to measure the robustness of different algorithms. We also report the relative mCE (RmCE) and the clean scores, i.e., clean OA for point cloud classification and clean mIoU for part segmentation. Please refer to our papers for more detailed definitions.


    If you encounter any problems, please get in touch with us at jiawei011@e.ntu.edu.sg and lingdong001@e.ntu.edu.sg.
