IEEE TITS (In Press, SCI, JCR Q1, IF=7.9, TOP Journal in Engineering Technology) 2024

This paper introduces WHU-Railway3D, a diverse point cloud semantic segmentation (PCSS) dataset specifically tailored for railway scenes. Spanning approximately 30 km and comprising 4.6 billion points, the dataset includes 11 richly annotated categories across urban, rural, and plateau railway environments.

ISPRS Journal of Photogrammetry and Remote Sensing (Under Review, SCI, JCR Q1, IF=12.7, TOP Journal in Geosciences) 2024

This study introduces a superpoint-assisted Neural Radiance Field (NeRF) for point cloud semantic segmentation without requiring additional training data. For a given scene, the proposed method uses point clouds, associated images, and image pseudo-semantic labels as inputs to achieve pointwise semantic segmentation.
