PointPWC-Net: Cost Volume on Point Clouds for (Self-)Supervised Scene Flow Estimation

We propose a novel end-to-end deep scene flow model, called PointPWC-Net, that directly processes 3D point cloud scenes with large motions in a coarse-to-fine fashion. Flow computed at the coarse level is upsampled and warped to a finer level, enabling the algorithm to accommodate for large motion w…
