PointNetVLAD: Deep Point Cloud Based Retrieval for Large-Scale Place Recognition

mikacuy/pointnetvlad CVPR 2018

This is largely due to the difficulty in extracting local feature descriptors from a point cloud that can subsequently be encoded into a global descriptor for the retrieval task.

LPD-Net: 3D Point Cloud Learning for Large-Scale Place Recognition and Environment Analysis

Suoivy/LPD-net ICCV 2019

Point cloud based place recognition is still an open issue due to the difficulty in extracting local features from the raw 3D point cloud and generating the global descriptor, and it's even harder in the large-scale dynamic environments.

PCAN: 3D Attention Map Learning Using Contextual Information for Point Cloud Based Retrieval

XLechter/PCAN CVPR 2019

Point cloud based retrieval for place recognition is an emerging problem in vision field.

DH3D: Deep Hierarchical 3D Descriptors for Robust Large-Scale 6DoF Relocalization

JuanDuGit/DH3D ECCV 2020

We generate the global descriptor by directly aggregating the learned local descriptors with an effective attention mechanism.

MinkLoc3D: Point Cloud Based Large-Scale Place Recognition

jac99/MinkLoc3D 9 Nov 2020

Thus, state-of-the-art methods enhance vanilla PointNet architecture by adding different mechanism to capture local contextual information, such as graph convolutional networks or using hand-crafted features.

SOE-Net: A Self-Attention and Orientation Encoding Network for Point Cloud based Place Recognition

Yan-Xia/SOE-Net CVPR 2021

We tackle the problem of place recognition from point cloud data and introduce a self-attention and orientation encoding network (SOE-Net) that fully explores the relationship between points and incorporates long-range context into point-wise local descriptors.

Pyramid Point Cloud Transformer for Large-Scale Place Recognition

fpthink/ppt-net ICCV 2021

In order to obtain discriminative global descriptors, we construct a pyramid VLAD module to aggregate the multi-scale feature maps of point clouds into the global descriptors.

Efficient 3D Point Cloud Feature Learning for Large-Scale Place Recognition

fpthink/EPC-Net 7 Jan 2021

In this paper, we develop an efficient point cloud learning network (EPC-Net) to form a global descriptor for visual place recognition, which can obtain good performance and reduce computation memory and inference time.

NDT-Transformer: Large-Scale 3D Point Cloud Localisation using the Normal Distribution Transform Representation

dachengxiaocheng/NDT-Transformer 23 Mar 2021

Benefiting from the NDT representation and NDT-Transformer network, the learned global descriptors are enriched with both geometrical and contextual information.

MinkLoc++: Lidar and Monocular Image Fusion for Place Recognition

jac99/MinkLocMultimodal 12 Apr 2021

We also identify dominating modality problem when training a multimodal descriptor.
