@ -461,6 +461,7 @@ If you already have a calibration file, set `calibration_type` type to `convert`
- Export calibration to `.qca.txt` within QTM.
- Copy it in the `Calibration` Pose2Sim folder.
- set `convert_from` to 'qualisys' in your [Config.toml](https://github.com/perfanalytics/pose2sim/blob/main/Pose2Sim/Demo_SinglePerson/Config.toml) file. Change `binning_factor` to 2 if you film in 540p.
- If you set your cameras vertically and the videos are rendered sideways, you need to rotate them and the calibration file before running pose estimation. [Use this script](https://github.com/perfanalytics/pose2sim/issues/136#issuecomment-2398110061).
- **From [Optitrack](https://optitrack.com/):** Exporting calibration will be available in Motive 3.2. In the meantime:
- Calculate intrinsics with a board (see next section).
- Use their C++ API [to retrieve extrinsic properties](https://docs.optitrack.com/developer-tools/motive-api/motive-api-function-reference#tt_cameraxlocation). Translation can be copied as is in your `Calib.toml` file, but TT_CameraOrientationMatrix first needs to be [converted to a Rodrigues vector](https://docs.opencv.org/3.4/d9/d0c/group__calib3d.html#ga61585db663d9da06b68e70cfbf6a1eac) with OpenCV. See instructions [here](https://github.com/perfanalytics/pose2sim/issues/28).
