Overview: Semantic segmentation allows you to label each pixel of an image with a corresponding class of what is being represented.
Steps to perform semantic segmentation:
Click on Label type and select 3D Semantic painting from the top left menu of the editor.
To Create a Paint Label, Select a class and use left-click to paint on Lidar.
Paint Selection: Click on Paint with Brush using Left-click on the left-hand sidebar. Use Right-Click on the mouse for selecting Painting Mode (Brush or Polygon or Cube or smart brush) to start painting.
Selecting Brush/Polygon/Smart Brush/3D brush from Top Panel: Click on Paint at the top panel and select “Paint with Brush/Polygon/Smart Brush/3D brush”.
To paint another category change category type and paint using left-click.
You can also adjust the brush size. The bigger the brush size, the more surface area it covers.
You can also view the point cloud that is painted in the camera view by clicking on the “P”.
You need to save by clicking on Paint at the top panel and then click on save or use Enable Autosave.
To erase, hold “e” or click on the eraser icon to erase the paint.
