Auto-Grounding for Cuboids and Polylines

Autogrounding is a feature that automatically aligns cuboids and polylines to the ground in a point cloud environment. This ensures that annotations are accurately positioned on the surface without requiring manual adjustments. By leveraging the sensor data, the tool detects the ground level and adjusts the objects accordingly, improving efficiency and consistency.

Steps to use Autogrounding

1. Select the Annotation

   1. Choose the cuboid or polyline you want to ground.

2. Activate Autogrounding

   1. Click on the Autoground option available in the toolbar.

   2. Alternatively, use the shortcut key (if configured) to trigger autogrounding instantly.

3. System Adjusts the Annotation

   1. The tool automatically detects the ground level based on the point cloud data.

   2. The selected annotation is adjusted and aligned to the detected ground.

4. Review and Fine-tune (if needed)

   1. Verify the positioning of the annotation.

   2. If necessary, make minor manual adjustments to refine the alignment.

5. Save the Changes

   1. Confirm the placement and proceed with further annotations.
