NuScenes Tracking: GT and Prediction track matching #331

Open sfxsalem opened 2 years ago

sfxsalem commented 2 years ago

I successfully ran tracking for the nuscenes dataset. I want to re-identify the tracked objects also by the original Instance_token that exists in nuscenes instead of the numerical tracking_id (Sort of matching between predicted and GT tracks/objects).

Could a distance comparison work in this case (similar to the tracking evaluation in nuscenes-devkit) or is it better to perform a bipartite matching between GT and Prediction ?

maybe distance based matching? Currently it seems to have a lot false positive boxes if we use low score threshold.
