2021-07-12 The submission on Codalab starts!

2021-07-10 Two benchmarks, Single-View Point Cloud Completion and Partial-to-Partial Point Cloud Registration based on the MVP database have been released.

2021-07-09 An open-source toolbox for Point Cloud Completion and Registration, MVP codebase, has been released.

2021 The MVP challenges will be hosted in the ICCV2021 Workshop: Sensing, Understanding and Synthesizing Humans.


High-Quality Data



Multi-View Partial Point Clouds


Complete Point Clouds

Description


We contribute MVP database, a large-scale Multi-View Partial Point Cloud database, which has several appealing properties:

  • First, MVP contains over 800,000 diverse partial point clouds, which are rendered by uniformly distributed camera poses.

  • Second, MVP provides high-quality incomplete and complete ponit clouds from rich categories. We use high-resolution virtual cameras for rendering partial point clouds, and high-quality complete ponit clouds are generated by Possion Disk Sampling.

  • Third, MVP supports many downstream tasks, such as completion and registration. The two benchmarks, Single-View Point Cloud Completion and Partial-to-Partial Point Cloud Registration, have been released.



Please read Download Instructions below to access the dataset.

Agreement

  • The MVP is available for non-commercial research purposes only.
  • All 3D CADs of the MVP are obtained from the Internet which are not property of S-LAB, The Nanyang Technological University. The S-LAB is not responsible for the content nor the meaning of these CAD models.
  • We use ShapeNet data to generate partial and complete point clouds, and you agree to be bounded by ShapeNet terms of use.
  • The S-LAB reserves the right to terminate your access to the MVP at any time.
