RIA-Net: Rotation Invariant Aware 3D Point Cloud for Large-Scale Place Recognition

RA-L 2024

Large-scale place recognition based on point clouds remains a challenge due to the geometric transformations in the scene. Among many geometric transformations, rotation is particularly challenging to handle in practice. Only a few works try to encode rotation invariance into learning based place re

SAGE-Net: Employing Spatial Attention and Geometric Encoding for Point Cloud Based Place Recognition

Wen Hao, Wenjing Zhang, Haiyan Jin

RA-L 2024

Point cloud based place recognition remains a challenging issue due to the difficulty in extracting and encoding local features into robust and discriminative global descriptors from large-scale scenes. In this paper, we propose a novel deep neural network named SAGE-Net (Spatial Attention and Geome
