Using this feature will mark all frames as not visible if the number of points inside the cuboid is below the configured threshold.
The process of using this feature is different depending on whether the object is considered stationary or dynamic. It is described in the chapters below.
Annotate the object across the entire sequence.
Set the start and end of the lifespans using the trim from the left and right.
If you do not set the start and end of the lifespan unwanted frames may be kept if points earlier or later on in the sequence appear at the last seen location.
Press the button in the left toolbar with a traffic light on it.
Go through the sequence and set properties.
If an error tolerance is configured for the 3D cuboids you may recieve a notification that some frames requires your attention. This occurs when there are points inside the margin, but the 3d box was marked as not visible. The affected frames will be marked in the video bar as seen in the image below.
Make sure the object is stationary throughout the entire sequence. It is recommended to use the aggregate point cloud feature point cloud aggregation feature to check if it's stationary or not.
Annotate the box using the side or center mode while the aggregate point cloud feature is turned on.
Press the button in the left toolbar with a traffic light on it.
Go through each frame in the sequence and set properties.
