How to clean point clouds

Modified on Tue, 23 Jan 2024 at 08:01 PM

Our cleaning tool does not support octrees or e57 yet.

Use File > Import to open individual LAS, LAZ, XYZ, TXT, or PTS point clouds.

For terrestrial laser scanner data, we recommend cleaning point clouds scan position by scan position.

Launch the Cleaning tool from the sidebar.

Choose from two brush types: 3D sphere or 2D marquee.

In 3D sphere mode:
- To activate cleaning, click or press & hold C.
- To select points inside the sphere, left-click and drag the mouse.
- To deselect points, right-click and drag.
- To change the size of the sphere, adjust the Size parameter or scroll the mouse wheel while cleaning is active.
- This mode is ideal for selecting specific objects.
In 2D marquee mode:
- To activate cleaning, click or press & hold C.
- To select a rectangular area of points, press & hold the left mouse button to define the first corner, then drag and release to define the rectangle's opposite corner.
- To deselect an area, do the same with the right mouse button.
- This mode helps you quickly select entire regions.
Reset unselects all points.
Delete removes the selection.
Create generates a separate point cloud from the selection.
