This is the official code repository of "Pyramid Semantic Graph-based Global Point Cloud Registration with Low Overlap", which is accepted by IROS'23. Pagor (PyrAmid Graph-based GlObal Registration) is a robust global point cloud registration algorithm for LiDAR. It takes two point clouds and ...
Publication date:September 2015 Abstract This paper addresses the problem of compression of 3D point cloud sequences that are characterized by moving 3D positions and color attributes. As temporally successive point cloud frames share some similarities, motion estimation is key to effective compression of...
Current methods for processing point cloud data are capable of extracting both regional and global feature information; however, the semantic information mining from point cloud data requires further enhancement. Additionally, there is a need to improve the ability to capture correlations between points...
