How to download data without video? Just IMU and keystep annotated.

[qingxinxia]

Hello

Thank you very much for your excellent work.

Could you give me advice about how to download the IMU data that has keystep annotated?

It seems the download tool does not offer such a command to filter video.

Thanks very much for your help!

Best

Hi @qingxinxia

To access IMU stream, you can download the VRS files without image streams (video data). Unfortunately we do not have the IMU pre-extracted, so you will have to use aria data tools Python API to extract it yourself.

You can filter the takes by benchmark via the --benchmarks flag, i.e. --benchmarks keystep

For example here is what your command would look like:

egoexo -o <out-dir> --parts take_vrs_noimagestream --benchmarks keystep

The size of this set is 434.0GiB. Does this work for your use-case?

You can see other file size breakdowns and CLI flag options here: https://docs.ego-exo4d-data.org/download/

Kind regards,
Miguel.

I'm waiting for the access key to download.

Hopefully, everything goes well.
