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.

A Dynamical Perspective on Point Cloud Registration

CoRR, 2020
We provide a dynamical perspective on the classical problem of 3D point cloud registration with correspondences. A point cloud is considered as a rigid body consisting of particles. The problem of registering two point clouds is formulated as a dynamical system, where the dynamic model point cloud translates and rotates in a viscous environment towards

Point Cloud Registration Algorithm Based on the Grey Wolf Optimizer

IEEE Access, 2020
In view of the long computation time and low registration accuracy of the current point cloud registration algorithm, a point cloud registration algorithm based on the grey wolf optimizer (GWO) is proposed, denoted PCR-GW.
