Matlab point cloud registration: point cloud transformation
Overview:
Point cloud registration is one of the important problems in the fields of computer vision and robotics. It involves aligning multiple 3D point cloud data for subsequent analysis and processing. In this article, we will introduce how to use Matlab for point cloud registration and show some related source code.
- Point cloud data loading:
First, we need to load the point cloud data. In Matlab, you can use the PlyRead function to read point cloud data from a PLY file. We assume that there are two point cloud data to be registered, named cloud1.ply and cloud2.ply respectively.
cloud1 = pcread('cloud1.ply');
cloud2 = pcread('cloud2.ply');
- Data preprocessing:
Before registration, some preprocessing operations are usually required on the point cloud data. For example, you can remove the
