MULTIPLE TLS POINT CLOUD REGISTRATION BASED ON POINT PROJECTION IMAGES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 In this paper, an efficient and robust registration method of multiple point clouds is proposed. In our research, we assume that point clouds are acquired by Terrestrial Laser Scanning (TLS) systems, and the scanned environments have a relatively flat ...

Partial transport for point-cloud registration
Sampling Theory, Signal Processing, and Data AnalysisAbstract Point cloud registration is an important task in fields like robotics, computer graphics, and medical imaging, involving the determination of spatial relationships between point sets in 3D space. Real-world challenges, such as non-rigid movements and partial visibility, including occlusions and sensor noise, make non-rigid ...

Rethinking Rotation Invariance with Point Cloud Registration
Proceedings of the AAAI Conference on Artificial Intelligence, 2023 Recent investigations on rotation invariance for 3D point clouds have been devoted to devising rotation-invariant feature descriptors or learning canonical spaces where objects are semantically aligned. Examinations of learning frameworks for invariance have seldom been looked into.

The Improvement of Iterative Closest Point with Edges of Projected Image
Virtual Reality & Intelligent Hardware, 2023 Background: There are many regular-shape objects in the artificial environment. It is difficult to distinguish the poses of these objects, when only geometric information is utilized.
