Inaccurate 3D bbox annotation

[yizhou-wang]

Hi team,

Thanks a lot for the valuable dataset!

However, we found many FPs and FNs annotations in the dataset:

Not sure if it is a dataset annotation issue. Could you please help check the problem?

Thank you so much!

Hi,

Thanks a lot for your interest in the dataset and for taking the time to look into it.

Yes, we are aware that there are inaccuracies in some of the annotations. Due to resource limitations, we were only able to manually clean the annotations for the first 8 cameras of the first sequence, and we recommend using those cameras for evaluation.

The annotations for the remaining cameras and sequences were generated automatically by aggregating detections from a 2D detector, and they are therefore noisier. Please keep this in mind if you plan to use them for training.
