Progress in 3D object understanding has relied on manually canonicalized shape datasets that contain instances with consistent position and orientation (3D pose).

… ConDor is a self-supervised method that learns to Canonicalize the 3D orientation and position for full and partial 3D point clouds.

… build on top of Tensor Field Networks (TFNs) … method takes an unseen full or partial 3D point cloud at an arbitrary pose and outputs an equivariant canonical pose.

… network uses self-supervision losses to learn the canonical pose from an un-canonicalized collection of full and partial 3D point clouds.

ConDor can also learn to consistently co-segment object parts without any supervision.

… approach outperforms existing methods while enabling new applications such as operation on depth images and annotation transfer.
