.PCD, .PLY, .LAS, .LAZ pointclouds

Overview

This option allows you to upload point clouds to the platform without any annotations. All items from the input directory and its subdirectories will be uploaded to a single dataset. If you need to preserve the directory structure, you can use the Import Pointclouds PCD application from the Supervisely Ecosystem.

Format description

Supported point cloud formats: .pcd, .ply, .las, .laz. With annotations: No Supported annotation format: Not applicable. Grouped by: Any structure (will be uploaded to a single dataset).

Format LAS/LAZ

During import, LAS and LAZ files are automatically converted to PCD (Point Cloud Data) format.

⚠️ Important: Coordinate Shift

During LAS/LAZ to PCD conversion, coordinate shift is automatically applied to all point clouds. This is necessary to:

• Avoid floating-point precision issues with large geodetic coordinates

• Prevent visual artifacts and rendering problems

• Ensure proper visualization in point cloud viewers

The shift values (X, Y, Z offsets) are logged for each converted file. Look for messages like:

Applied coordinate shift for filename: X=1234567.89, Y=9876543.21, Z=123.45

If you need to use annotations with original LAS files or convert back to LAS format:

• Save the shift values from the logs

• Add these shift values back to your PCD/annotation coordinates to restore original geodetic coordinates:

  original_x = pcd_x + shift_x
  original_y = pcd_y + shift_y
  original_z = pcd_z + shift_z
