We propose a method for generalizing deep learning for 3D point cloud registration on new, totally different datasets. It is based on two components, MS-SVConv and UDGE. Using Multi-Scale Sparse Voxel Convolution, MSSVConv is a fast deep neural network that outputs the descriptors from point clouds for 3D registration between two scenes. UDGE is an algorithm for transferring deep networks on unknown datasets in a unsupervised way. The interest of the proposed method appears while using the two…

Self-Supervised Point Set Local Descriptors for Point Cloud Registration
TLDR
The capability of the self-supervised local descriptor to achieve even better performance than the supervised model, while being easier to train and requiring no data labeling is demonstrated.
The Perfect Match: 3D Point Cloud Matching With Smoothed Densities
TLDR
This work proposes 3DSmoothNet, a full workflow to match 3D point clouds with a siamese deep learning architecture and fully convolutional layers using a voxelized smoothed density value (SDV) representation, and shows that 3DS moothNet trained only on RGB-D indoor scenes of buildings achieves 79.0% average recall, more than double the performance of the closest, learning-based competitors.
PointNet: Deep Learning on Point Sets for 3D Classification and Segmentation
TLDR
This paper designs a novel type of neural network that directly consumes point clouds, which well respects the permutation invariance of points in the input and provides a unified architecture for applications ranging from object classification, part segmentation, to scene semantic parsing.

TLDR
This work proposes a learning-based method, titled Deep Closest Point (DCP), inspired by recent techniques in computer vision and natural language processing, that provides a state-of-the-art registration technique and evaluates the suitability of the learned features transferred to unseen objects.
End-to-End Learning Local Multi-View Descriptors for 3D Point Clouds
TLDR
This work proposes an end-to-end framework to learn local multi-view descriptors for 3D point clouds by using a differentiable renderer, which allows the viewpoints to be optimizable parameters for capturing more informative local context of interest points.
D3Feat: Joint Learning of Dense Detection and Description of 3D Local Features
TLDR
This paper proposes a keypoint selection strategy that overcomes the inherent density variations of 3D point clouds, and proposes a self-supervised detector loss guided by the on-the-fly feature matching results during training.
Self-Supervised Pretraining of 3D Features on any Point-Cloud
TLDR
This work presents a simple self-supervised pretraining method that can work with single-view depth scans acquired by varied sensors, without 3D registration and point correspondences, and sets a new state-of-the-art for object detection on ScanNet and SUNRGBD.
DeepVCP: An End-to-End Deep Neural Network for Point Cloud Registration
TLDR
DeepVCP is presented - a novel end-to-end learning-based 3D point cloud registration framework that achieves comparable registration accuracy to prior state-of-the-art geometric methods and the low registration error and high robustness of the method make it attractive to the substantial applications relying on the point cloudRegistration task.

TLDR
A new convolutional neural network (CNN) to classify 3D point clouds of urban or indoor scenes that beats the state of the art of point classification methods (those not using a regularization step).
PointNetLK: Robust & Efficient Point Cloud Registration Using PointNet
TLDR
It is argued that PointNet itself can be thought of as a learnable "imaging" function, and classical vision algorithms for image alignment can be brought to bear on the problem -- namely the Lucas & Kanade (LK) algorithm.
