Introduction

ScanNet is an RGB-D video dataset containing 2.5 million views in more than 1500 scans, annotated with 3D camera poses, surface reconstructions, and instance-level semantic segmentations. To collect this data, we designed an easy-to-use and scalable RGB-D capture system that includes automated surface reconstruction and crowdsourced semantic annotation. We show that using this data helps achieve state-of-the-art performance on several 3D scene understanding tasks, including 3D object classification, semantic voxel labeling, and CAD model retrieval. More information can be found in our paper.

Acknowledgments

The ScanNet project is funded by Google Tango, Intel, NSF (IIS-1251217 and VEC 1539014/1539099), and a Stanford Graduate fellowship. We also thank Occipital for donating structure sensors and Nvidia for hardware donations, as well as support by the Max-Planck Center for Visual Computing and the Stanford CURIS program.

Toan Vuong, Joseph Chang, and Helen Jiang helped develop the mobile scanning app, and Hope Casey-Allen and Duc Nugyen developed early prototypes of the annotation interfaces. We thank Alex Sabia for scanning and verifying annotations, and Halle Pollack, Julian Massarani and Michael Fang fo checking annotations. Last but not least, we would like to thank all the other volunteers who helped with scanning and getting us access to scanning spaces, as well as all the AMT workers who annotated and gave us feedback on the interface design.
