Hello Naveed,
I understand you wanted to extract/access the elements of pointcloud in MATLAB.
To extract or access elements of a point cloud in MATLAB:
  • Location Data: Access XYZ coordinates.
locations = ptCloud.Location;
  • Color Data: Access RGB color values if available.
colors = ptCloud.Color;
  • Accessing Normal Vectors: Normals, if available, are stored in the .Normal property.
  • Loading a Point Cloud and Reading point cloud using "pcread" function.
You cab refer to the below documentation for more information on Pcread:
