When labeling a static object in 3D point cloud sequences, a single frame might not show the object in full detail. It can thus be difficult to assess the full dimensions of an object.
To solve this issue, you can toggle a merged point cloud view.
This video shows how you can use the merged point cloud view to draw a perfect cuboid around a static object.
Toggle the merged point cloud view
Click on the merged point cloud icon () in the right toolbar to toggle the merged point cloud view on/off.
