Point Cloud File I/O

Read and write 3-D point cloud data in MATLAB using Lidar Toolbox file I/O functions, covering PLY, PCD, LAS/LAZ, sensor PCAP, E57, and IDC (Ibeo) formats.

When to Use

• Loading a point cloud file from disk into a pointCloud object
• Saving a pointCloud object to disk in any supported format
• Deciding which reader or writer function to use for a given file format
• Reading LAS/LAZ files with selective filtering (ROI, classification, GPS time)
• Extracting or preserving lidar point attributes (classification, GPS timestamps, scan angle)
• Reading Velodyne, Ouster, or Hesai PCAP sensor recordings frame-by-frame
• Reading multi-scan E57 files with indexed access
• Reading Ibeo IDC sensor recordings with message-based access
• Converting between point cloud formats (e.g., LAS to PLY, PCD to LAZ)
