CorrI2P: Deep Image-to-Point Cloud Registration via Dense Correspondence [PDF]

IEEE transactions on circuits and systems for video technology (Print), 2022
Motivated by the intuition that the critical step of localizing a 2D image in the corresponding 3D point cloud is establishing 2D-3D correspondence between them, we propose the first feature-based dense correspondence framework for addressing the ...
