Polyline Direction
To make lane annotation more intuitive and accurate, directional arrows now appear during polyline creation.
Helps ensure correct lane flow and orientation, especially for traffic-related annotations.
Benefits
Reduces confusion about line direction.
Improves annotation consistency for downstream models.
Speeds up QA by making intent visually obvious.
Steps to Use Polyline Direction
1
Draw a polyline
As the polyline is drawn, arrows will indicate the direction of the line.
2
Verify orientation
This helps ensure correct lane flow and orientation, especially for traffic-related annotations.
Reverse Direction
After drawing the polyline, right-click to open the contextual menu and instantly reverse the direction. This change will be applied across the entire sequence.
Hide Direction
Once the polyline is created, the same contextual menu lets you hide directional arrows to minimize visual clutter during annotation.
Directional arrows are automatically hidden when the annotation is not selected.
