Object Track
Object Track allows users to visualize the entire track of a selected cuboid across a sequence. When enabled, it displays all instances of that cuboid—before and after the current frame—providing a full view of the object’s trajectory. This feature is particularly useful for reviewing dynamic objects and catching inconsistencies in their annotations, such as misalignment, missed frames, or sudden shifts. Object Track is a good and fast review tool that enhances annotation quality while minimizing the time spent scrubbing through frames.
Visualize and verify an object’s full trajectory across frames to ensure consistent, high-quality tracking.
Use Cases
Autonomous Driving – Moving Vehicles and Pedestrians Visually confirm consistent tracking of dynamic objects like cars or pedestrians over time to ensure high-quality training data.
Robotics – Tracking People or Equipment Indoors Use Object Track to validate that moving people or tools in indoor robotics datasets are annotated consistently across frames.
Agri-Tech – Monitoring Moving Machinery or Livestock Confirm that tractors, drones, or animals are correctly tracked over time in long sequences with intermittent motion or occlusions.
Benefits
Good: Increases annotation quality by making it easy to spot tracking gaps, misaligned cuboids, or frame skips.
Fast: Saves time during review by surfacing the full track in one view—eliminating the need to click through each frame.
Lean: Lightweight toggle-based feature that fits seamlessly into existing workflows with no added complexity.
Steps to Use Object Track
Select a Cuboid on the current frame.
Toggle on 'Object Track' by pressing 'T'.
The tool will display all cuboid instances from the full sequence associated with the selected object.
If this object is acting as stationary, then all cuboids will appear at the same location
If this object is dynamic, then all cuboids will appear in the track.
Use this visual context to verify alignment, consistency, and presence across frames.
Make corrections as needed based on visible anomalies.
Tip: Enable Object Track after completing tracking. Any edits made while this feature is active will automatically update the full track, thanks to keyframe interpolation
