A custom AlphaShapeclass was used to extract the boundary points of the point cloud data and…
The Open3D library is used for point cloud processing and visualization.
Three functions are defined:
RANSAC plane segmentation and visualization of point clouds using the Open3D library.
Crop a planar point cloud by polygon selection volume and visualize the result.
DBSCAN density clustering and visualization of point clouds using the Open3D library.
This code is used to generate point cloud data for a plane that is described by the parametric equation Ax + By + Cz + D = 0.
