2 weeks ago hello,
Thank you for your inquiry.
To clarify, the object_lidars directory is indeed not optional, it is a necessary component of the standard dataset structure. This contains each objetcs lidar pcd and can be generated from the raw lidar pcds. This involves using the object tracklets to accumulate lidar points within bounding boxes for each object from all frames, followed by a transformation to the object frame.
Due to other commitments, I am unable to publish the full preprocessing pipeline at this time. However, I can share the preprocessed data for the three scenes we utilized, along with the script we used to generate them if need be.
I hope this helps.
Best regards,

Dear sntubix, I hope this message finds you well. I am writing to seek clarification regarding the KITTI-MOT dataset organization as described in your documentation (attached screenshot). Specifically, I noticed that there is no mention of any lidar data within the specified directory structure.
As per the diagram provided, the expected structure includes directories such as calib, completion_02, image_02, and others, but it does not explicitly show where the lidar data (object_lidars) should be located. The diagram indicates that object_lidars contains files like object_id.ply.
Could you please provide more information on how the lidar data should be organized within the KITTI-MOT dataset? Additionally, could you confirm if the object_lidars directory is indeed part of the standard dataset structure?
Your insights would be greatly appreciated as they will help me better understand the correct way to organize and utilize the lidar data from the KITTI-MOT dataset.
Thank you very much for your time and assistance.
