Request for VRS / calibration files for accurate Aria gaze projection
Hi, thanks for releasing this dataset.
I would like to project the provided EyeGaze CSV data onto the EgoLife egocentric RGB videos. The CSV files provide yaw / pitch / depth values in CPF coordinates, but accurate Project Aria gaze projection should require VRS and/or camera calibration files, including RGB intrinsics and the CPF-to-RGB camera transform.
I could not find VRS files, MPS calibration files, or camera calibration files in this repository. Without them, it seems only approximate projection using assumed FOV is possible.
Could you clarify whether VRS / calibration files are available, or whether there is an official way to map the EyeGaze CSVs to RGB video pixels?
Thanks!
Hi, thanks for your interest on our work.
To be transparent, we are not fully familiar with the exact calibration / projection requirements for Project Aria gaze-to-RGB reprojection. The EyeGaze CSVs in this release were generated internally, but we are not currently sure which specific calibration assets are strictly required on top of the provided yaw/pitch/depth values.
It is possible that the required information (e.g. RGB intrinsics, CPF-to-camera transforms, or related calibration procedures) is already documented in the official Project Aria documentation and tooling.
Regarding VRS files: we may be able to provide selected portions or corresponding metadata if there are specific fields/assets that are necessary for reprojection. However, the raw VRS recordings are extremely large and also contain sensitive information, so we unfortunately cannot release the full set publicly.
That said, we may be able to provide a short segment of VRS data for debugging or validation purposes. Once it is clear what information needs to be extracted from the VRS files, we could potentially process and release only the necessary subset instead of the full recordings.
If you can clarify exactly which components are needed (for example: specific calibration fields, MPS outputs, or particular streams from the VRS), as well as which subject / date / time segment is required, we can check internally whether a limited release is possible.
Thanks again for raising this issue.
