You can use
register a moving point cloud to a fixed point cloud. The registration
algorithm is based on the iterative closest point (ICP) algorithm.
Best performance of this iterative process requires adjusting properties
for your data. Before using
downsample your point clouds, which improves the accuracy and efficiency
Understand point cloud registration workflow.
Apply rigid registration to align two point clouds.
This example shows how to combine multiple point clouds to reconstruct a 3-D scene using Iterative Closest Point (ICP) algorithm.
