1. Vehicles Annotation: Annotate all vehicles that possess at least one LiDAR or radar point, ensuring reasonable determination of their location and shape. Exercise your judgment to accurately size, position, and orient them.
2. Accuracy of LiDAR View: Objects should be faithfully represented in the LiDAR view. In most cases, confirm that the cuboid encompasses all LiDAR points associated with the object.
3. Priority given to LiDAR View: Correct annotation in the LiDAR view takes precedence over appearing accurate in the camera view.
4. Consider Discrepancies in Camera View: Remember that the camera view may exhibit distortion while the LiDAR view remains reliable.
5. Primary Source: Rely on LIDAR point clouds as the main reference for annotation. Utilize CAMERA images to aid in determining the object.
6. Use of Camera Images: When objects have few LIDAR points, consult camera images to ensure accurate sizing of the bounding boxes.
7. Consistent Object IDs: Maintain consistent object IDs throughout the task. If an object disappears and reappears, continue annotation using the same cuboid rather than creating a new one.
8. Uncertain Object Continuity: If uncertain about whether it is the same object (e.g., occlusion with a group of birds, a vehicle disappearing and reappearing), exercise your judgment and try to assign the appropriate object ID. If impossible, using an alternative object ID is acceptable.
9. Compact Cuboid Size: Ensure the cuboid tightly fits around the object. The cuboid should closely align with the object's edges without excluding any LiDAR points.
10. Stationary Cuboids: Do not label any cuboid as "STATIONARY." This option is not enabled for this project.
11. Tag Attributes: All tags, except FREESPACE, come with associated attributes. Fill in the attributes for each object in every frame.
12. Detailed Instructions: The Jackrabbit LiDAR instructions contain comprehensive information. Most of the material covered in this course is included in those instructions.

Please note that annotation instructions for project batches may change based on customer requests. Always refer to the To-Do List after receiving a task in the queue for the most up-to-date instructions.

Project Guidelines LINK

• All labels except for FREESPACE have their own unique attributes, including visibility.
• FREESPACE labels have no attributes.
• Most of the attributes that can be configured on the lower part of the sidebar are self-explanatory, but some are a bit more complex, like the visibility attributes.
• Adding attributes must be done EVERY FRAME the object appears.
• When double-clicking on attributes, make sure they are the same across all frames where the object is present.
• You can also use shift-clicking on the frame bar to select multiple frames, from the current one to the one you clicked. This is useful for changing attributes in multiple frames at once.

Workflow
Annotation workflow:

Scan the scene.
Assess and identify the objects to annotate quickly.
Start annotating from the nearest side of the SDC. Begin with frame 1 and annotate everything up to the last frame. Do not proceed to the next frame(s) until you are confident that everything is identified and will be annotated. Repeat this method for the other side and into the middle.
Review and attribute if everything is annotated. This is a good practice to re-evaluate your annotations and ensure that no objects are missed. Although time-consuming, it is efficient, especially for beginners or cautious individuals.
Attribute right after annotating each object. This speeds up the process and keeps you focused on the area. However, it is important to double-check your work. Always review all available cameras for each frame the object is present and confirm if the DAPC (Data Acquisition Point Cloud) is accurate.
Annotate everything in the Drivable space first. By focusing on the road at the beginning, ensure that any objects that may pose a hazard to vehicles or the SDC are identified and labeled as part of the Other label group. It is critical not to miss this step.
Include at least 3-5 cuboids of Freespaces per frame.

Other workflow instructions:

Regularly sync your work to save everything.
Address any linter warnings and do not dismiss them. Always investigate and resolve them.
As a reviewer, fix only what are necessary, obvious, and critical errors.
Provide constructive feedback or information about mistakes. Consider providing screenshots to help others learn and improve their work.
Submit complete and high-quality output. Avoid having others fix your tasks. Aim for a customer-ready task at all times.
