About

PointCloud-C is the very first test-suite for point cloud perception robustness analysis under corruptions. It includes two sets: ModelNet-C (ICML'22) for point cloud classification and ShapeNet-C (arXiv'22) for part segmentation.

*Note: Standalone indicates whether or not the method is a standalone architecture or a combination with augmentation or pretrain.

Evaluation

Evaluation commands are provided in EVALUATE.md.

Customize Evaluation

We have provided evaluation utilities to help you evaluate on ModelNet-C using your own codebase. Please follow CUSTOMIZE.md.

Build PointCloud-C

You can manage to generate your own "PointCloud-C"! Follow the instructions in GENERATE.md.

TODO List

• Initial release. 🚀
• Add license. See here for more details.
• Release test sets. Download ModelNet-C and ShapeNet-C from our project page.
• Add evaluation scripts for classification models.
• Add evaluation scripts for part segmentation models.
• Add competition details.
• Clean and retouch codebase.
